    Have 14x19 4 blade on 4.3 GXi. Upgrade to Stainless Steel worthwhile?

    Thank you to everyone that has taken time to reply - lots of helpful ideas. I should have clarified that my main goal is to improve the hole shot for getting slalom skiers out of the water and I don't care if the Vmax drops from 48mph down to the low 40s.

    Circa 2008 4.3 GXi (SX-A) Possible to increase power/performance?

    On a 2008 (could be an '07 or '09, can't recall) Stingray 195X bowrider with a Volvo Penta 4.3 GXi-J and SX-A 1.66 outdrive, are there any simple ways to improve engine output and performance? The throttle response off-idle is quite soft and the boat struggles to pull a ~200lb slalom skier out...
