As an EX. yammie techie I can say you have been "HAD". The dealer will
put
the correct prop on it (he has dozens of extras for just such a need) and
charge you for water in the gas He probably put in the boat. If it was
not
mis-firing-it did not have water.

Didn't the original post say that he was originally getting 4400 (or so)
rpms,
and that after a couple of trips the rpms dropped to around 3200. I'd say
something was misfiring.

And I can assure you that on a fuel injected engine small droplets of
water can
be mixed with the gas and get through the filter can and will cause
premature
fouling of the plugs. It doesn't take much for a new lean burn engines to
not
properly fire. Not usually a problem on carb'ed engines where fuel /air
mixture
is not so critical.

If they change the plugs and clean the fuel tank and them tell him he
needs to
go down in size on his prop, I'd say he probably hasn't been "HAD".

His Reply:

So I went down to pick up the boat. Aside from doing the 10 hr
checkup and the "water in gas" problem. He had not even put the boat
in the water!! We took the boat out and sure enough was only able to
run 4600. He says "well we might have to check that prop size" I
knew it!!!! Two smaller prop sizes later and she was up to 5500 right
where she should be. Then this guy had the audacity to say after he
has had the boat for two weeks " I should have done this earlier in
the week" Do you beleive that?????!!!!! Needless to say I will never
put another penny thru that guys shop. Thanks to all who posted
advice and comment. It was a 175$ lesson to learn.





Just out of curiosity, what was the diagnosis of the rpm loss that was
originally mentioned. I think you mentioned when your father used it he could
only get about 3200 rpm from the original 4600. Did that just disappear when
you went out with the mechanic?

He probably changed plugs with the 10 hour service.

Other than taking too long to look at your boat, how did the mechanic screw
you? What was the $175 charge? You got the 10 hour maintenance. And what? A
new prop? Or 2 hours of his time to change props a couple of times and go for
test rides? I didn't think that was all supposed to be free.

No offense meant but I'm missing something here. Unless you're saying it's his
fault that you had the wrong size prop.......But even then, you should have
known from the first day you went out and got 4600 rpm's that you were
overpropped. You wouldn't have needed to take the boat back for service. Just
change props. I've never seen your boat and I could have told you to go down 2
sizes in pitch.
