New-Used Boat Question

[yrsfather]

New to the forum. Just bought a used 2002 Crest 20Ft Sport. It has a 40 horse 2 stroke which has a built in oil mixing tank. My neighbor recommended to still mix the gas/oil for the first tank of the season. This would insure that the mixing injector is working(level will go down). He said there will be no engine damage if the gas is oil rich. Does this seem to be the correct thing to do? Any other tips would also be appreciated. Thanks.

Sounds reasonable to me.

I burned up a new jet ski motor once because the oil pump was not working. I bought a couple skis from a friend, one had a blown engine. Turned out the reason for the blown engine was the oil pump was not working. I put a new engine in and premixed the first tank per break in procedure. First tank of gas all was good. Filled up the second tank of gas without premix and the engine siezed in about 3 minutes. Luckily the reman engine company's warranty covered it no matter what. Put a second engine in and ran premix all the time with no problems.

Mine was unhooked when I got the boat so I have premixed all the time, but I read where the other side was the fuel pump and they say it should quit all the way or nothing.

But I haven't even tried to use the oil pump or checked to see if it was working, but premix and check to see if pumping oil too, just make sure your low oil alarm is working if you start using it.

Welcome to the forum yrsfather!

That sounds like good advise your neighbor gave you. You do the same thing when you breakin a new outboard. The worst thing that would happen is maybe foul a spark plug. I always keep a new set of pugs on the boat with a ratchet just in case I foul one and it starts to run rough. It takes seconds to change them out.

Have heard the same thing years ago. Far as I know still good advice. Get some type of measuring cup if you have the gallon size of oil. It will help pouring also. My old toon had the tank inside the cowl with a flip up door to put the oil in. I picked up a small watering pitcher with a long spout an it was perfect for filling the tank without spilling. Think I would back off a little on the recommended mix. That way it would protect the engine and reduce the chance of fouling if the pump is working correctly. Good Luck

you will contribute to global warming but you won't mess up your motor that way.
