Re: Need some infor on turbo hot shot
If the 15" aluminum prop gets you in the right rpm range then the 15" HS will too but will allow you to raise the motor some for improved efficiency. However, if the 15 aluminum isn't in the right rpm range, the HS won't (most likely) be either.
If the 15 aluminum is in good shape and puts you where you want to be, the 15 HS is a good choice.
