hey guys i currently have 260 twin merc engines with alpha drives...they have clever props and the boat runs good on top end but out of the hole they suck..i know thats how they are designed...i want to tube and ski with my kids and want to know what size and pitch anyone has used that works really well with my engine horsepower and drives......with the clevers i can run 58 to 61 on gps at 4600 rpms....just want a really nice holeshot for the toys and was hoping for any help...thanks...impulsive1
