Hey guys,
So, to start I need to tell you guys that I have just bought my first boat. its a 1990 Arriva speed boat with a 150 hp Force outboard motor. I bought it from a guy on my fire dept. who assured me that when the boat was last used (2 year ago) It ran perfectly was then winterized. He didn't want it anymore, so he gave me a great deal. My dad has been helping me a little bit. I am sorry for my terminology as I am still learning. We replaced the lower end gear lube. It was black but there was water in it. I have been doing as much research as I can trying to filter out what I need. I put some fresh fuel in the tank after draining out the old little bit of fuel and there was almost nothing in the tank, hooked my hose to the motor to see if it would turn over. The motor backfired once during the initial first 2 cranks then it started right up ran for a few then died. I am happy that it started. There was no water coming out from the top 2 holes. I think they are called the pisser? I also didn't see any water coming out of the exhaust. Now where I live the water pressure sucks. so some advice please. Should I attempt to replace the water pump and reseal kit or test it out first. I am pretty mechanical. I needed a project because my wife made me sell my car I worked on a lot. It was fast enough to mandate a roll cage at the drag stip. Anyway what should I do before I take it onto the lake?
The motor is the original motor that came with the boat. I could not find any info plates. I will attach a few pictures of the motor tomorrow when I can. Its a 5 cyl. 150 hp Force. It says US Marine on the plate. If you could tell me more about it that would be great.
Please help me if you can.

Thanks,
Kris

Here are some photos of the motor and boat. I figured out how to post them and the file size limitations for the site.
Thanks,
Kris

Re: New to boating

First thing you should do is a compression check. Replace the water pump impeller and both of the fuel pump diaphragms. If the impeller and diaphragms are marginal and you take it out and they fail, you are dead in the water. Water in the lower unit could be the lower unit seals or the washers under the fill and vent plugs. Make sure the lower unit is filled to the very top so the the upper drive shaft bearing get lubrication. You might have to let it set for a while after you fill it up to let all the air bubbles rise to the top. Then top it off again. Also get rid of the loose pieces of foam. Don't want any of it to get sucked into the carbs. Install an inline fuel filter between the last fuel pump and the carburetors.

It has the Prestolite ignition system which is around 1989ish - 1991ish.

Re: New to boating

That sure is a clean and great looking motor. But since it hasn't been run in years first things first: You already changed the lube oil on the LU which is good. Next, as previously mentioned you need to change the impeller, for the non-experience that is virtually the water pump located on the lower unit. Next is to install a clear fuel filter between the fuel pump outlet and the carbs' inlet, this is more of a troubleshooting aide than anything else. Replace the spark plugs. Replace the primer bulb. And finally, do a test ran with the cowl off and watch everything to make sure the carbs are not overflowing. And finally, make sure you know proper starting procedures for this Force motors. If you don't it will frustrate you and give up what seems to be a very good motor.

Re: New to boating

I already removed all of the loose foam from the cowl. I figured that was bad news. Do you have a few links to for the fuel filter or is a universal style fuel filter. I have a new fuel hose that I am going to install because I heard they go bad every few years if you don't use ethanol free fuel and since I have no idea the fuel used before I figured that it was better to replace now and avoid the headache. I was looking up an impeller kit but I am still not sure exactly which kit is right for my motor. I am fairly sure its an 89 but I have no idea if its an A or B motor. What does the L driver refer to? If you could post some links to help me that would be great and thanks for the advice already and the more to come in advance!

Re: New to boating

Here's the impeller for your boat, available right here at iboats.com They come in two makers, I always get the Sierra for it seems to be made better although it costs about $0.50 more. I change mine every two seasons, since I ran my boat only like 30~50 hours a year. I order two units at a time just to make sure I have spares on hand.

Re: New to boating

Being an "A" or "B" model in your case is virtually indifferent although you can figure that out referencing the serial number which is located on the left hand side of the transom mount. As for the "L" drive, (I believe this is what you are referring to) this is an entirely different model which is basically an outboard motor configured as an inboard and uses an "L" drive shaft to drive the prop.

Re: New to boating

This all depends on the state of the wash plate and gasket. Personally, I only replaced the impeller since the wash plate (water pump plate) seems to be in good shape although they do have dirt built up on them. You might want to try replacing the impeller first since storing the motor doesn't necessarily wear out the wash plate or gasket.

Since the foams already fallen.
Take the covers off the carbs and check out the throats of the carbs.
If the ID sticker is gone? You can tell what year by taking off the bracket that holds the electronics.
On the top cylinder should be a foundry stamp. The center of the stamp is a number. Usually the year it was made.
If your boat is a 90 the motor's probably a 90.
Take a few pics of the fuel pumps and hose routing.
Filling the lower: I fill from the fill/ vent then switch to the vent/ fill until it comes out both holes.
Arriva is a Bayliner with a different name. Same company.
If you send an e-mail to Bayliner with the hull ID# they can tell you what model and serial # motor came with your boat.
They even have owners manuals.
The water pump probably doesn't need a new housing. Post a pic.
My twin 88/85's use the same pump as yours and they are original and have been used in salt water since new.
I buy filters from Wally world Fram G-2 or G-12 depending on fuel line size.
Install it after the last pump before the carb.

Re: New to boating

Ok guys So checking the boat out a little bit. I have been really busy with overtime and very cold and rainy around me lately add the honey do lists and spending time with my 2 young sons, I don't have too much time at the moment. But, I did take the motor of the transom saver and hooked up the battery again and noticed that they hydraulics on the power trim are not holding. while in the half way up to travel height the hydraulics the motor will slowly sink back down to the bottom and sit straight up and down. I do not see any leaking around the pump seals or around any of the lines. Any advice?

Re: New to boating

Either the seals ("O" rings) in the Tilt or Trim cylinder need to be replaced, or the seals in the valve body where the metal hydraulic lines hook up under the pump are bad.

Hey guys,
I bought it from a guy on my fire dept. who assured me that when the boat was last used (2 year ago) It ran perfectly was then winterized.

We replaced the lower end gear lube. It was black but there was water in it.

Make sure you go over your rig with a fine toothed comb before getting it out on the water. If it was properly winterized, there should've been no water in the lower end. About the only real maintenance item to do on an outboard for winterizing is tilt the motor down to drain the water, and then change the gear lube so that if there is water in the gearcase, there is no danger of it freezing and cracking said gearcase. Not to question the honesty of a fireman, but water in the gearcase of a supposedly winterized boat would be a red flag for me.

Re: New to boating

As for the tilt and trim problem, search the forum for previous threads. There are test to confirm if it is the cylinders needing new O ring or the spool valves in the valve body. It is really an easy fix either way, although personally, I find repairing the spool valves easier.
