Tedious,
Thanks again for much good information. My last question would be about trim. I might of forgot to mention it up front, but the 5000 RPM was at between 3/4 down and 1/2 trim on the trim gauge. I didn't notice a significant rpm increase while trimming the motor up as on past boats I have owned if memory serves me right. How high do you trim to get max rpm's while not porpoising or robbing the motor of the ability to pump water? On older 2 strokes I have owned I have really never went too much higher than I did on my test run with the Yamaha.
