The engine runs great after just being rebuilt. Recently though it
would run hot while running on plane. I then noticed that it was not
peeing when on plane. The impeller has 25 hours on it. Owned the
boat and engine for 8 years and it never had this problem before and
the engine and boat were sold together new. The first time I remember
it happening was just after I had gone through a weeded area. Maybe
something clogging somewhere? Any ideas on flushing it out? Thanks.
