fuel in oil

[joni]

Hi,

I have 2 boats. In each both there's 3 bf 225.
In one boat the engines did 1000 hrs and the other did 1300 hrs.
The problem is that theres fuel in the oil in all the engine's.

What seems to be the problem?

Most likely it is something that is making your motor run rich, the motors were not properly broken in, or you are using incorrect oil (synthetic).

At the top of the list to make your motor run rich is the motors are not coming up to temperature.

You could have bad thermostats or stuck bypass valves. Those are probably the most likely place to look. Chawk seems to be the one with the most practical experience on these.
