has anyone ran a 35 gtr on a lowe roughneck boat? i currently have an outboard and was looking to make a switch. not really interested in buying a new boat though. what kind of performance can i expect out of this motor on a 1756 roughneck?

I think you will run 28 MPH with a stock 35.

Rudy how did u come up with that speed? Do u know someone with A similar setup?

Some of the guy’s hunting Lake O have the 1754 running the 35 MB. I raced them back with my tin can. I was doing 26-28 alone. Both doing about the same speed.
Not sure if they had work done on the motors.
