Wanted to share my 1st boat buying experience. Has definitely been a learning experience!! Hopefully some of the things i've learned over the last 4.5 weeks will keep others from having the same problems!!

It started with doing a lot of searches on craigslist in all the major cities around where i live in southern ohio. It's amazing how many people won't call you back or even respond once they list something for sale on craigslist. Anyway, after sending out probably 20 emails, texts and phone calls, only 2 people contacted me back.

I decided to go look at a boat on the west side of dayton, about 1.5 hours from my house and at least an hour from the nearest body of water. With that being said, kind of precluded a water trial which would have kept a lot of my problems from happening. I had tapped lots of resources to ask questions about what boats are worth, engines that are reliable and the ones to stay away from (OMC) so when i go there i thought i had a decent grasp of what i was looking at.

1 big thing to consider when buying on craigslist, price is negotiable!! The price started at $1800 on craiglist, had him to $1500 before i left the house, final price after seeing the boat was $1100 for boat and trailer.

The boat is a 1985 Sea Sprite 185XL with a 3.7L Mercruiser and an Alpha 1 sterndrive. Single axle trailer with surge brakes. Outside of the boat is in pretty good shape, the interior and floor was awful as it had been left sitting outside uncovered. I knew the seats and floor were a loss and factored that in. I knew enough not to start the motor without a pair of muffs on it, i did turn it over to make sure it wasn't locked up. Crawled underneath it to inspect the hull, put my full weight on the stern drive to see if there was any flex in the transom which is solid. Thank god!! So i decided to give it a shot!!

So i buy the boat, PO hands me the title and i start home with my new toy, i'm a proud new boat owner!! Couple things to note here, in Ohio, the bill of sale is a one way ticket to get the trailer home without registration on it!! Not for sure how it is in other states. Was pulling the boat with a Ford Explorer Sport Trac, knew the boat was back there but the truck pulled it home just fine and at interstate speeds!! Was not use to pulling a trailer and curbed a tire on a turn in a small town. Busted a cord in the sidewall, expense number 1 and hadn't even got it home yet!! LOL

Got the boat home and stop at the state BMV the next day, more lessons learned. The title is for the boat, not the trailer. Got the title transfered into my name. The trailer is considered a non-comm trailer in ohio so to get plates the state of ohio wants to know the EMPTY weight of the trailer. Yep you guessed it, have to figure out a way to get the boat off the trailer, take it and have it weighed, then get the boat back on the trailer and take the weigh ticket with you to get the plates. So far so good!!

The PO had told me the starter needed replaced. The positive battery terminal would get extremely hot to the touch when you turned the motor over. From talking with mechanic friends and such, this means there's a dead short somewhere. The current is going straight to ground and pulling a lot af amps which builds the heat.

So my next stop was dropping the boat off at Francis Marine @ Rocky Fork Lake. In my grand scheme i figured it was most important to make sure the power plant was sound before i started the resto of the seats and floor. No since in having a pretty boat with a ****ty motor!! I checked with friends that own a boat at this point again to find a decent boat mechanic, which is few and far between out here!! Hindsight here taught me to use a established mechanic because problems found with the motor and stern drive were caused by somebody taking the stern drive apart and not putting it back together right!!

So, we're now 4 weeks into having the boat looked at. The battery has been moved closer to the starter to fix some of the overheating battery issues, the heat exchanger was dropped to put the new starter on. New starter ($206) installed and a crack was found in the heat exchanger, PO didn't winterize the boat correctly, water was left in the heat exchanger which froze over the winter and cracked the copper housing. Heat exchanger new price = $700, part found from a boat salvage yard on ebay, $176 with shipping. Gotta love ebay!!

The 1 time the mechanic had the engine running, yes the motor runs!! YEAH!! Heard a knock in the stern drive. Mechanic was scheduled to drop it anyway as when it was running it was pumping no water. We had already discussed replacing the impellar and gear oil in the stern drive so he was going to go all the way through it while he had it apart. After pulling it apart we have found that an oversized seal was used and lake water had gotten into things it should'nt have inside the stern drive. $123 in bearings later and the stern drive looks to be ok from here. Another point of note, when the stern drive was taken off, they put no spline grease on the shaft when they put it back together!! Its now started to round off the tops of the splines. Gonna have to replace it within a couple years according to the mechanic, chose not to do it now as the engine would have to be pulled out of the boat to facilitate it!! U-joints were ok, some wobble in the gimbal bearing, gonna go ahead and replace it while we're there as a gimbal bearing going out can destroy the gimbal housing which is an expensive repair!! About $25 for a new gimbal bearing!

I think the mechanic has grown weary of my questions but he has tolerated me!! LOL, i'm the type of person that just doesn't want it fixed, i want to know how it's supposed to work and how to take care of it so it doesn't go out again, hence a million questions. So i guess i tried to write this so that maybe other 1st time owners/buyers may avoid some of the pitfalls that i have run into. According to the mechanic, the boat should be ready for a water test by this wednesday (8/17/2011). Repair bill with all parts and labor so far is going to be between $500 and $750, i'm ok with this as blue book on the boat once the resto is done is in the neighborhood of $3500. As i continue on my journey i'll try to update this thread as i move through the seat project and redoing the floor.

Hope this will help others and feel free to comment with anything you think i should be aware of or have missed!!

Re: My 1st experience!!

Well an update.

Had a fair amount of pitting on the lower unit due to the anode being broke and not replaced by the PO. Replaced that anode and added a 2nd one. Also more bearings replaced behind the prop due to poor maintenance. Found pieces of the impellar near where you put the muffs to run it out of the water, replaced the impellar and gaskets. Lower unit is now in tip top shape and back on the boat.

Pulled the exhaust bellow as it had a bad spot in it, the flapper inside was in good shape but in checking the exhaust, found a crack in the exhaust manifold, thank god it didn't go anywhere. Mechanic says we can slap some jbweld on it and it'll hold till i have the cash together to convert from a closed cooling system to an open cooling system.

What is everyones thoughts on open vs closed cooling systems??

Anyway, almost 6 weeks in now, boating season is almost over in southern ohio but should have the exhaust manifold back otgether tomorrow, put the heat exchanger back on and we should be good to go from there hopefully.

After the engine work is done, on to rehabing the floor and redoing all the seats. Didn't really want a project boat but it has helped me learn so much more about my boat and what to make sure is taken care of!!

Happy Boating all

Re: My 1st experience!!

Interesting experience. I have also purchased my first boat about a month ago, for 400$. With a few repairs and some regular tuneups I have splashed and very happy with the investment.

Good luck on your restoration, and trust me, you will learn a lot about boats meanwhile.

fwiw, i'd not be impressed if i had a 'mechanic' (using that term loosely) that said something like that. bum manifolds and risers cost owners new engines due to water intrusion into the engine. how do you know the manifold isn't cracked inside too? i think the recommendation should have been get a new manifold, riser too while your there. + not use it till ya do, unless ya want a different engine.
to convert from a closed cooling system to an open cooling system.

you have a 3.7 mercruiser engine. it's got a alum. block and a iron head. from what i understand, these dissimilar metals expand and contract at different rates when they get warmed up. the closed system you have is the way mercruiser kept everything at a constant temp. i don't believe that it is recommend to convert to raw water cooled on a 3.7 engine.
everything i've ever read leads me to think that fresh water cooled is better than raw water. ya got anti freeze in your block. corrosion resistance. raw water cooled don't. closed is better, specially if your boating is salt. while i'm no pro and don't know all the ramifications. i've read enough to know that the 3.7 must have a closed cooling system.
i think maybe ya need a different 'marine tech'. these two recommendations from him lead me to think he's not hip. for sure he don't read iboats. at least not often enough.
that's my shade tree (non schooled, opinion) marine tech thoughts.

glad yer having fun with her though. that's most important..

Trying to keep it positive for you, so I recommend you do searches here for the Merc 3.7 . There are 2 or 3 key upgrades to keep it from becoming a troublesome land-locked money pit. Those have over-achieving type power for their size but have some kinks that put it into the "Use Caution Before Purchasing" list. Good luck on your project!

Thanks for the info on the cooling system. As for the manifold, had it off the boat at the time, mechanic filled the water passages with gasoline and let it set for 24 hours to see if it whicked into the exhaust passages. No moisture in the exhaust side after 24 hours. Have since splashed it for a check ride. Mechanic on board, hit about 40mph at WOT. Repair bill was already approaching $900, didn't like the price of replacing that manifold as well.

Can you direct me towards the threads your referencing. Would love to do those upgrades!!

Re: My 1st experience!!

Well. the enthusiasm is starting to wane. Almost $1000.00 in engine, lower unit & carb repairs and i took the boat out this morning with my wife and son.

Needless to say was not overly impressed about having to paddle the last 100 yds back to the dock!! Managed to get it done and winched it onto the trailer.

It ran fine for about 1 pass of the lake then started running rough. Limped it back towards the boat dock but you could tell the engine was struggling, would rev up then back down. 100 yds from the dock, died and wouldn't restart. Strong odor of gas.

It's back at the mechanic now, thinks it might have water in the fuel tank!!

Re: My 1st experience!!

What was the condition of the gas? If it had been sitting for a while and not stabilized like it should have been (since it was not winterized like it should have been), then it may be old gas. I would flush it, add fresh gas, and replace the filter (maybe twice).

Re: My 1st experience!!

How long did this boat sit? Could be bad gas/water in gas and your carb is most likely gummed up and needs a rebuild. Get yourself a good manual and you can do a lot of maintanance yourself and save big bucks. You got that boat for pretty cheap and the fact is you've done pretty well only having to put $1000 into it so far. As others have stated have your mechanic do the correct repair and replace the manifold with a new one. You mentioned the floor was bad. Are we talking soft spots? If so you really need to check the condition of the stringers before dropping more money into this boat. Often times when the floor is soft the stringers below are mush. Hopefully thats not the case.

Re: My 1st experience!!

Me1st, just do searches here or the entire web for Merc 470 or 3.7LX and you will find the problems with this engine and what changes need to be made to get them more reliable.


This is what I remember, and my terminology may not be corrects in all items.


Too small heat exchanger, needs to be 4" model. Early 470's had a 3" model. Again, don't quote me on the numbers but there is a too small one that needs to be upgraded if you have that one.

Add more typical external alternator to replace internal stator/magneto style device, remove glued on magnets from flywheel. If the magnets come off they will take out other stuff inside.

Cam sealing, needs to be some machining mods to prevent water coming in from the pump thru the front of the engine here.

Head gasketing is tricky, there are no dowels for the head to mat to on the block. Head gasket composition is very specific too I think. This is related to the heat exchanger causing overheats then the head gasket goes or head or block warp.

Re: My 1st experience!!

They run those 470's in sprint cars down here. I had a pair in a 23 Nova 11. Guess I was lucky the boat sank before I ran into these issues. My understanding is that was a Ford head and a Mercury block.

Actually already took care of this issue. Part of the repair process has been to replace the heat exchanger, put a 4" model on it as had read that it wasn't recommended to use the 3" due to the overheating issue!

Did some research on this one, cheapest i have found is almost $600, is that accurate or am i searching for the wrong thing?

Wow, sorry to hear your boat sank!!

Found the Mercruiser #8 manual on another thread, is that the one i would need?? From glancing at it, i think it is??

The PO took horrible care of this boat!! I rescued it and gonna give it a new lease on life. There was a little gas in the tank from the previous season. The mechanic had it started several times on muffs and it idled fine. We took it out for a check ride and it died on us once at WOT. Started right back up though and the mechanic adjusted some screws on the carb. Seemed OK. I put $25 in gas in it thinking it would freshen what was in the tank and allow me to flush it though. guess not!

Ok guys. Really, really need some advice. Drained the fuel tank today. About 9 gallons of gas.

Seemed ok to me but didn't have the strong gas smell. Smelled kinda weak if that makes sense. Ordered a carb rebuild kit and a fuel / water separation kit.

My question is feeling real unsure of myself at this point. Not for sure if I'm getting in way over my head.

What r your experiences with rebuilding the carb etc and what was your skill level when u started??

Don't want to screw it up worse than it already is!!

Re: My 1st experience!!

With the service manual and some basic skills it can be done by the boat owner. I recommend you take several pictures of the system before you tear into it. If you are not comfortable, have your (new) mechanic do the job. Old fuel will cause all kinds of issues, while the carb rebuild is a good start; the entire fuel delivery system needs to be inspected and possibly updated. That includes a clean fuel tank, with new fuel lines, and filters that will not rot due to the new fuel we are forced to use. I would bet once you get that fuel system in good shape, you will enjoy the boat, and gain some confidence when using. All the other stuff you have been fixing is really critical stuff too.
So the big question is what would have done differently in buying this boat, knowing what you do now? A sea test, or at least starting the boat, is an absolute must IMO. The next thing to consider is taking your mechanic with you when looking at a boat. Lots of people get surveys to ensure they don?t buy a lemon, or at least know what the boat will need to be water ready, the cost of the survey is nothing compared to one major issue, or several small ones.

A good used boat is often the best, for a first boat, because you are learning, and there are bound to be mistakes, I know, I made many of them. Hope you are able to get back out this year, but if not, you will have all winter to get her running the way you want.
