OK Thanks. Should I lower the engine first? I am about a fuzz below the jackplate mount (at the first notch) with the motor mount. Can you give me some idea of the RPM and speed I should expect for a fairly loaded boat. Say regular gear and 500 lbs in human weight (say not all mine). If I know about what to expect I can see results the next time I open up. Like I mentioned before, I am getting more use to chine walk. In fact, I was showing my son how to handle it. By the way,I have just about given up on the Yamaha speed gauge. The inlet in the motor keeps getting stopped up. The low 70s is by GPS. Any help is appreciated. Maybe the motor is about right, huh?
