Looking for help. I had motors rebuilt winter 10/11. also had like new used drive installed, mine was shot. after replacing throttle possitioning sencors, MAP sensors, and changed gear in drive supposedly it was mis-labeled.
I have tested both units to make sure they are the same, and they are 2.0 to 1. bravo 3 drives with 24 pitch blades.
If we trim the motor out at speed it comes up on rpm. What should I check next?
