Ok we had our new tritoon out yesterday to put some hrs on the motor after 3 hrs I started to open it up at 3/4 it took off like a scared rabbit and hit 36 MPH trimmed I looked down at the tach and it was over 7000 RPM I know this cant be true as it had a lot more to go. It is a 150SHO running a sds 14.5x15. Is it possible the dealer set it up for a different motor. It seems fine at idle 900 RPM I have not checked the back of the tach yet.
