Outboard boat taking on too much water in splashwell

Re: Boatt

Re: Boatt

You have a short shaft engine mounted on a transom meant for a long shaft engine. Somebody did a "hack" job on the transom that not only looks like s---t but is dangerous. I would suggest either using a transom bracket and repairing the transom at least to it's original configuration or again restore the transom (probably by replacing it) and installing an engine of the correct shaft length.

As it is, I think your boat, with "no foam" is a future dive site.

Re: Boatt

After looking at pics again I wonder why the waterline is so high on a 18' boat.Is there a built in fuel tank in the stern area.I know it is a deep v but something is out of whack.Without that heavy I/O setup I would think it would float like a cork.The waterline should be a couple inches at the most above the stern chine line.[Where the sides meet the bottom at a right angle]If you have a 20" leg it should work with a bracket or JPlate.

I suspect that the CB (center of balance) of the boat has changed significantly. The off shore bracket with a sponson is now sounding like the best cure other than putting a I/O back in it. When I was building a tinny from Glen-L plans, the difference in the I/O and Jet version was significant when compared to the outboard version.

If you read the whole thread you will realize that the original configuration was inboard/outboard.... we started with "junk it" but now it looks like a SLIGHT chance that it should be built.... At some point geography can make logs and coconuts lashed together with vines (MAN did giligan's island have an endless supply of those) a seaworthy vessel.....

Re: Boatt

the weight of my engine is 320 .lbs kicker 9.9 65 lbs plus batt.6 gall fuel tank.could all this weight factor in why water is level with transom.boat is v hull.would adding more weight to bow,compensate for this problem.just curious.guys you all have been great.

Re: Boatt

Re: Boatt

a mercruiser 260 complete with the outdrive weighs close to 1000 lbs.... On my old 20' cuddy, two guys over 200 lbs each on the swim platform only dropped the stern a couple inches....You could try pulling the outboard off and floating it but I think there will be very little change.... you could also put a couple of fat friends in the bow but again I doubt you'll see any real gain....
sure you have weight further back but you also have quite a bit less weight than you could have with a v8 i/o which that hull should be fine with
I think that transom needs to be a foot taller

Adding weight to the bow would compensate a bit but it's kind of like building a brick wall to shield yourself from a fire in your kitchen instead of putting the fire out. Sooner or later the fire's gonna burn the house down.

Re: Boatt

Re: Boatt

this is the third bad i/o to ob conversion i have seen today.

The biggest reason for the conversion was the omc stringer drive....the thought was......just plug the hole and hang a big ol ob off it.
The conversion rarely works. the owners are not satisfied with the results.

As mentioned above......do not use this boat on big water.....small calm lake at best. you are at any time a second from sinking.

But im curious.......how do you KNOW no foam?

there is another fix.......you can get a conversion kit to a long shaft, and repair/replace the transom. if you do this.....There is a bit more work to do.....and you will still have a conversion......the owners rarely like the results. but i have heard of 3 successful conversions.

the cost for a long shaft lower for your motor. is about 500 bux used.
the transom dyi is 800 max.

i like the free hull idea.......but you will still have a short shaft in big water! not a good thing to have.

you have lots to think about.
sorry you got soaked.

Whoah ... sneaking up on "bad to worse." Can you see the stringers?

 

[ringo111]

Re: Boatt

Re: Boatt

i dont see stringers .boat is ribbed in fibreglass moulding/on each side fm bow to stern everything looks solid and dry.i have decided to sell my motor and put on 70 hp.

 

[oops!]

Re: Boatt

Re: Boatt

we still have to fix your transom bud.

even if you go with a new to you long shaft.......you will need to build up that transom..

can you post pics?....lets look inside that puppy and see what we can come up with for you

will do

Re: Boatt

Re: Boatt

Here are some pics for you to look at. Pics are of the transom inside and the bottom of the boat. Also motor and transom.

That second pic is gonna make me lose sleep.

Re: Boatt

Re: Boatt

what did you notice

 

[oops!]

Re: Boatt

Re: Boatt

well ringo......you will have some work ahead.

its not hard work....but its at least 40 hours.

the transom was not properly sealed....it looks like rot has started. in the second pic there is leakage coming from the lower open hole. im betting there is rot in there....
but no matter....this was looking like a full transom any how.

what you will need to do....is remove the top half of the boat....(or just cut the back section) remove the old transom by cutting/prying/grinding....but leaving the outer skin.
and replacing the wood with new wood that is taller. then we have to re build the splash well area to accommodate the new taller steering system.

this sounds like a lot of work....because it is....but the guys here do this stuff all the time.

if you are willing to do this......we are willing to walk you right thru it.

the cost will be around 500bux....possibly 800.....
we can help you with the materials....the tools.....the proper "how to's. but the elbow grease must be supplied by you.

for a quick reference.....click the link im my sig....the first few pages are on the transom removal/ replacement.
there are also other links about outboard transom removals in the restoration forum here.

we are more than willing to help....but the choice is yours.

cheers...keep your chin up
oops

btw......by the time you are done.......you will be able to go as high hp as a 200 if you wish, without worries

Re: Boatt

Re: Boatt

the water you are seeing at bottom hole.is rain water.that never completly drained through hole, i tapped all a round transom it is solid no soft spots what so ever.i have taken motor of now ,and will send more pics with it off,a few posts back it was mentioned about installing a transom bracket.and fill or glass in back.what do you think.

 

[ringo111]

Re: Boatt

Re: Boatt

Here are the pics.

 

[oops!]

Re: Boatt

Re: Boatt

lol....sorry ringo....i didnt mean the drain....i ment the motor mount hole on the right side lowest.

even tho the transom is rot free.....im worried about just adding another chunk of ply on top of where the transom was cut lower...then glassing that in.....ypu will still have weight and thrust hanging off the back of a non structural part......i suppose you could if you put a big ol piece of metal across the whole area.. but thats hack.

the top cap will still have to be modified to accomidate the new taller position steering rod....but that is no big deal....

so...the question is up to you.....

do you just want to get out on the water asap?

do you want to fix this thing semi properly to last for a while.

or do you want to fix the boat so its right because you are going to keep it for a decade or so?

whatever you choose.....its ok.....its your boat.....you can fix it the way you want....we just have to kow how to proceed with repairs.

cheers
oops

Re: Boatt

Re: Boatt

even if it IS actually solid, unfortunately, it still needs to come out if you want to make it into a safe dependable boat.... It's cut too low.... This is why we were steering you toward a whole new boat..... It CAN be rebuilt properly but there is just no easy bandaid fix.
