I got a 225G yesterday with same problem. Wont go to high speed under load when on turtle. Runs fine if left on rabbit.
Duane, I did all these checks and everything checks good except on the ICM, pins G-E measured 2.5mvAC no load. I know you say 0 vac so does 2.5mv mean its bad?
Also where to buy the icm if it is bad. M4less wants $236. Seems a little high to me?
Thanks to all for giving this info
