Apologies if I didn’t mention it earlier, but I did adjust the high speed needle at WOT. I’ve basically done all the prescribed treatments, and like I said, the motor is running like a champion. It still can’t push the boat though – the prop is just too high in the water. It sounds like like a modern i/o if you forget to lower the trim. My extension kit should arrive today and I should be back on the water tomorrow with an update.

As you leaned out the HS needle at WOT, did you notice improvement in power with the increased rpms?
