I think I have the wrong pitched impeller in my new jetboat. I'm not getting the performance that I expected.
I have a 24 ft Weldcraft with the 454 and a 2.4 TBO impellar. I'm only running about 24 mph at 3600 rpm, takes 4300 to get up to 29 mph. I'm thinking I need something more aggressive.
Any one have any insight? Idealy I'd like to see if someone has a 3.4 that I could try out without having to buy one.
