hi this is my first post i'm new to boating and I bought a 1989 Bayliner Capri with a 3.0 OMC motor the boat sticker has a date of 2003 but the guy I bought it from said he had it in the water one time last year about a week before I bought it it rain enough to fill the back of the boat and water ran down the carb i drained off two and a half gallons of water out of the oil pan but nothing was in the pistons I installed new plugs in it and new gas but still no start Did I buy a lemon here or is this boat worth saving thanks for your help.

Re: 3.0 under water

Is the engine froze up, or will the starter spin it ?

no the engine spins over a little slow but not fast enough to start

There are 3 things needed for a motor to run. Air, fuel, and spark. If you can breath, you have air. If the plugs are wet with fuel, or you can see the jets squirting when you take the spark arrester off and look down into the carb, you have fuel. Pull the coil wire and make sure you have spark by letting it sit about a quarter inch from a good ground. If that works, pull a plug, leave the wire on, let it sit against a good ground (the block) and see if you have spark there as well. If all that is there, it will fire.

Re: 3.0 under water

Did you drain the carb? Did you clean the points in the ignition?

Re: 3.0 under water

Start with the basics...get an owners manual and go through the basics of normal maintenance and then hit the trouble shooting section for how to start your engine. Check your battery to make sure its fully charged and all connections are good. Clean and gap your plugs. Drain out the old gas, put in fresh gas and a can of carb cleaner/HEAT. Check your oil level and that all belts/hoses are hooked up and fine. Be sure your water drains (block, manifold) are closed. Hook up the muffs and try to start it up. Make sure the laynards attached, in neutral, etc, etc... What does it do?

Make sure you battery has a good charge. If it is turning to slow I would imagine the battery is low or bad. Unless of course the engine has that much friction from rust that it is having troubles turning over.

Did you put any penetrating oil (PB Blaster is my fav) in the cylinders. That might help free things up.

Re: 3.0 under water

One other consideration. you say the starter turns slow. If the batteries check out and the cables are in good condition, clean tight....the starter may have gotten submerged. If that happened it will have to come out. Take a light and a mirror and take a look. It will be obvious if its all rusted up.

Re: 3.0 under water

one rain was enough to fill the back of the boat high enough to run down the carburetor?

quite a rain......were the animals pairing up? d:)

just kiddin...I'll bet you don't have severe damage. My boat had the same thing happen to it before I got it and I can't tell any ill effects. It supposedly sat with the engine submerged for a week before anyone noticed. I had to replace the alternator but when I took the starter off to check it, I really couldn't see any sign of water damage. That was in April 05 and it still seems fine.

Re: 3.0 under water

Sounds like you just learned that the water in the pan didn't come from the rain. Time to track down where it's coming from...

Re: 3.0 under water

but wouldn't it show up at the repair shop that something was wrong they ran the motor to operating temp. the flush the motor and it ran for about 5 minutes when i picked it up they had the water ears hooked up does that also supply water to the engine. When I picked the boat up the motor runs better than the one in my truck. I saw i little water dripping off the intake manifold or was coming from the top right side on the motor i think.

Re: 3.0 under water

OK, you really have three options here and they are independent of each other 1) Assume everything is working correctly and in good shape because the repair shop said it was 2) Begin your own investigation 3) Take it back to the repair shop and inform them you still have the water problem, but it's not from rain like you originally thought.

Number 1 and a good tow line will get you out on the water, i.e. it's out, because you know you're stil getting water in your engine. If you told the tech that your engine flooded due to rain, they cleaned it out for you and probably did not go into too much detailed troubleshooting for the source of the water as you told them where it came from. If you had told them you were getting water in your engine from an unknown source your results (and bill) would probably have been different.

Number 2 is what the people on this board can help you with. Somewhere in the archives there is a diagnostic list for water ingestion. You need to go through it step by step until you find your problem. If you don't want to spend the time diagnosing it and working on it, then

Number 3...

I suggest number 2. The faster you de-mystify marine engines the more money you will save and the more confident you will be going out.

The muffs you saw do in fact supply water to the engine. A small leak may not show up in 5 minutes of running on the muffs. Find the dianostic, or maybe someone will post a link to it.
