went very well. That 18 footer with the 150 hp Yamaha is a screamer, but I
only got it up to 3900 RPM. The day turned out beautiful, if a little cool
and breezy. The boat handled the small (one foot) chop in the Rappahannock
River with ease, and I was very impressed with the engine. The engine
rocks, almost noiselessly. At 3500 rpm I could carry on a conversation
with
the maintenance guy in a normal tone of voice.
Congrats!!!

Why only 3900? Is that a Yamaha break-in suggestion or are you overproped?
I just repowered my 17 whaler outrage with a 150 opti and had to play some
games with pitch and diameter before I got to 5400 RPM. Just curious..


I hadn't read the manual yet, so don't know the break in procedures. This
was just a test run. I'll save this post and try to remember to get back to
you once I've read the manual and taken it out for a longer workout.


Your dealer didn't go over break-in procedures for the new engine?
