What is the height of your drives off the bottom of you boat? I am trying to do some home work but can not get any measurements. ? Botttom of hull to center of prop shaft. Mine is 4". If I had a 35 with 502mpi's I would put pro chargers on and hang on. we have guys running them here and love them.

Your numbers suggest that the drives are 1.5:1. You would be running in the high 90's with 1.36:1. I would not be surprised if Leon rebuilt or swapped the upper gears out of your drives and replaced them with a 1.5 set.

I bet you are right about the ratio on the drives, the boat just dont feel like it is slipping , I need to turn the engine over 1 full revolution and see how far the prop turns

I have 1:36 gears in mine and all calculations say near 90 but I am at least 9 off. I know the motors are fine , the loss in speed must be in the drive. I want to try -2 and this will put the prop shaft two inches up. ???????????????? Another thing If I took all the stuff that my wife puts inthe boat out, it might run 100.
