Welcome aboard. I was curious as well. I saw it was answered in another thread.
Trip to the lake was a huge disappointment, 96 degrees, no wind, too much prop, motor too high, less top end and the motor malfunctioned.
It would only turn 5400 trimming to the moon. I had a rider that saw 52 mph on the gps. The motor will need to come down two holes. The center of the gearcase is now 2" below the bottom of the boat with the 30" setback. On plane I can see the water 2" below the ventilation plate and at this height the prop is surfacing with trim at wot although water pressure was always good. The prop is ventilating somewhat in the turns. The setup was not right and going to the 21p Thunderbolt was too much prop. I will have to send it off to be re-pitched since I bought it.
The motor dropped off about half way thru the test session. Something crapped out with the fuel system or the ignition. It wouldn't even get on plane. I don't think I hurt it too bad, it still has a good smooth idle. I am happy it died in the lake instead of the Gulf of Mexico but
NOW WHAT?
