I just had the 20 hour check done, I have only had the boat out once since..
One thing they did during the check was switch the prop out to keep the
rpm's in the right range.. When I hear the noise is sounds as though
something is skipping off a gear! I also noted it seemed to shift in to
reverse very hard. Thanks Tom

I would also be suspicious of computer problems.... since this is
intermittent, it may be detonation and/or misfiring....

if there is any detonation involved, you'll *really* want that paper
trail when the engine comes apart.... notice I didn't say "if."

That's a good point - didn't think of that.

Sounds like practical experience.

Later,
