I have a 98 Mariner 200 hp 2.5 L Magnum EFI on a 98 Bass Cat Pantera 3. My boat came with a 23p Tempest plus 3 blade and I’m getting 57 mph gps running 5,800 rpm but I’m also only at about 3/4 throttle. So after doing some research I’ve been told I need to run a 25p fury or trophy 4 blade. After talking with some buddies I got 2 25p trophy 4 blades to try out. Both of them are a lot smaller diameter that the prop I have now. I did try one of the props but was getting serious cavitation around where it meets up at the lower unit. I’m assuming there’s no way I can do anything to make them work?
