    I think we all know and realize that the angle would not be correlated with any internal gear ratio.

    But if you reduce the ratio, you’re gonna want to take advantage of its benefits by ramping up the prop diameter, and that has challenges when it comes to a thrust vector and a forward moving boat coupled with adequate hull clearance.

    Again, all heresay. But I like the belligerent BS call! Makes others feel good. 🤣

    Yes. With Mastercraft now running a 20” prop on the X-star, then that requires a steeper Driveline angle to for more hull clearance, unless they change the hull design instead.

    The other thing is that with lower ratios and bigger props with more pitch (as a consequence) the torque on the Propshafts has seen a major jump, with boats moving towards a 1-1/4” shaft instead of the regular 1-1/8” shaft. This increase in diameter although not trivial, is also questionable whether it is sufficient as there are numerous reports of people shearing the shaft right off with these higher ratio setups.
