Too much oil will foul the plugs and will not give you optimum burn rate
which provides optimum performance. It can also cause excess carbon buildup
in the engine and over time can cause heat buildup and detonation to occur.

I never saw a response to my other question - how do you use the engine.
Lots of top end running, lots of idling?

Can burning too much oil hurt anything? It's hard to get anyone to
look at anything in the summer.

Yes, I think it's burning too much oil. I'd expect 2 per 100 - or less.

NO you don't wanna screw with it. A 225 Opti is *far* too expensive a
motor
to repair to risk "fiddling" with such a critical system as the oil
injection.

That's one problem to take to a competant mechanic and have checked out.

Change your own plugs, do your own waterpump and lower unit lube, but
don't
go sticking the "golden screwdriver" into an Opti.

The boat I just bought has a Merc 2000, optimax 225 engine, it seems
to burn too much oil. It seems to use about 3 gallons of oil for
every 80 gallons of gas.. Is there an adjustment or some likely
thing to check.

Thanks,
Jon
