gas on water

[rubennh]

Hi everyone, I am new in the forum and i have a little problem with my 1988 125hp Force , i went to the lake yesterday and i noticed gas around the engine while in the water. I really do not have a lot of experience with boats, this is my first one, after a while the engine died, my questions is, what are the most common places to find gas leaks, what should i replace? (sounds simple, but i really wanted one good advice from one the professionals here at the forum)


Thanks so much!

Re: gas on water

Check the gaskets on the carb bowls. Also check all of your fuel lines, if they are original it might be a good idea to replace. Fuel line and hose clamps are cheap. The gaskets on the bowls to go bad and that could be the source of your leak. A rebuild kit will have the gaskets in them.

My old O/B did the same thing. Carb rebuild, new fuel lines, new bowl gaskets = no more gas in the water.

It would be a good thing to go ahead and replace them anyways, whether they are leaking or not. If you have owned the boat and not replaced fuel lines and done a carb cleaning/rebuild, it won't hurt to do it. Cheap Insurance!!

Re: gas on water

Go to the store and buy some Simple Green and a smaller scrub brush.

In your driveway spray down the whole motor and surrounding areas. Brush what looks grimy. Hose off. Once you got it all cleaned up. Take it out on the water for a while. (have fun too.) then once you get it back home, pop the coewl off and see if you can see any oil/gas leaks around.

This "Gas leak" you see around the motor in the water, this wouldn't just be the unburned fuel from the exhaust would it?

But cleaning everything up should narrow it down. especially if you see the oiliey mess over most of the motor and cowel.

Re: gas on water

Are you going by what the water looks like around the engine? Do you smell gas? It could also be a leaking lower unit maybe leaking gear oil. It gives the same appearance as fuel in water.

Re: gas on water

Unfortunately, two strokes are not the cleanest of motors[emissions wise] and will leave a streak due to the exhaust outlet being under water,and this is normal,unless your fuel economy just sucks or you see an obvious fuel leak you may not have any thing wrong. I would check to see if any fuel is leaking into the lower power head area,or an oil leak from the lower foot, otherwise keep on boating
