Thanks Don. You woukd think the water separators came with the fully rigged bass boats. I will check mine out on Monday.

Ship.....most but not all of the new boats come with them. The older boats do not have them unless someone added it on. With todays ethanol gas it is very important to have one.

Mine is a 1981 Venture Bass Boat.

I was introduced to Seafoam through my marine mechanic in Florida name of Bill Yates. Small shop with a strong following because he didn't waste his time or your money. He told me of his introduction to it and it went something like this; He was brought a 20hp tiller handle Mercury that and older gent liked to slow troll with. It just wouldn't behave, running rough and cutting out. Bill was the second tech to try and solve the problem. With the owners blessing he went through the carbs, twice, and the ignition system from top to bottom, changed nothing. One of the fellas that hung around from time to time came in and after learning of all the head scratching going on, he went to the parts house and came back with a can. Doing the choke and soak thing, Bill let it sit for a few hours while he tended another motor. He added some more fuel to keep the mix strong and fired it up in the test tank. He had to back away from the tank for all the smoke and black soot coming out of it, and had to change the water when finished. Seems the trolling had built up carbon and ash deposits and wouldn't let the motor breathe as it should. The motor went back to purring as it had before and the man paid his bill with a big smile. I don't use it every tank but run a can every few months in about a half tank of fuel and have no fuel related problems. I do run Marine Stabil religiously with every tank. My Jimmy's intake gaskets failed in a water jacket and the Nephew changed them. When he lifted the intake off and turned it over he couldn't believe what he was seeing and asked how I kept the injectors so clean. Motor had 153,000 and they were perfect. Stuff was developed in the 40's for marine applications and after talking to every mechanic I could find I have yet to hear a bad word about it, and that in itself speaks volumes. I'm as sold as I could be on the product. Like your new boat Mike, looks like a charm. Good luck with it.

Skeetbum's post reminded me that I have (somewhere) the procedures for doing a de-carb using Sea Foam. It does an excellent job when done right. When a motor is left sitting and not ran for a very long time it is fairly common for 1 cylinder to have low compression. This would be the one at the top of it's stroke and rings will stick from carbon and being compressed for a long period. I have seen this stuff free the rings and restore compression. It can get very messy from cleaning the motor out and is not something you would want to do on a nice clean driveway.

Thank you my friend. It has a 90hp on the rear end.

You are the first one to say "Don't do this on the driveway." I appreciate that tidbit of information. I guess I will just have to mess up the back yard. LOL

In case you don't have it, here is the procedure I use to use when I was working on motors.

+1 on everything said. Seafoam goes in everything I own. Do the decarb procedure mentioned. Its the best way and what I have always done. I bought a small jug for just seafoam decarb procedures.

There is another product that was mentioned earlier. Seafoam Deepcreep, it is a penetrating oil by nature. But is used the same way seafoam is used, just in aerosol form. Pull plugs and spray in, let set overnight...will loosen all the carbon from your rings and combustion chamber.

Like Bill said...NOT in driveway....or around any houses or people. It will SMOKE....ALOT...and leave a trail of black gunk.

One other thing...when doing any decarb on a boat motor...the chance is always there to foul a plug. Have a set with you when you do the decarb. That way you have them if needed. If you dont' foul any and they have any age on them I would go ahead and replace after the decarb. I always made a point to do this after the full on decarb.

Another tidbit...you can use it the same way in your vehicle. Ecspecially if you run an older carb or throttle body injected engine. Carb engines will surprise you at the gunk that comes out...due to the fact they never hold their mixtures right...and are normally not touched enough. Pull the Big vacuum tube off the brake booster. This is the big round thing on the firewall that attaches to the master cylinder..where you add brake fluid. With engine running you'll feel a vacuum (sucking) from hose...that leads right into the intake manifold. Slowly pour seafoam into that hose with engine running until it nearly dies...have engine warm when you do this. Allow to sit for 15 minutes...then drive the hound out of it. Do this a few times, put the rest in the tank if you have any left. You'll clean your intake, valves, pistons, combustion chamber and such. Normally add some milage back if its down.

Point being...you didn't go wrong buying it...nor will you ever go wrong using it. Great stuff!
