Thanks!! Took out the boat tonight with two people, a good amount of tackle between both of us, and 3/4 tank of gas. I saw right at 50mph, water pressure was between 15-20. The tach was at 5300 and it wanted to keep going but i held it there cause redline is only 5250 on this motor. Not sure how accurate the factory tach is?? Have not measured exactly how high the motor is but eyeballing it seemed like the plate is about 2in above the bottom of boat , maybe a touch higher.
