I bought my boat this spring, and it had a bit of vibration when accelerating. It also had a worn out cutlass bearing and bent strut... I've replaced the strut and aligned the drive and still have the vibration, though it is now in a narrower RPM range.
Boat is a '92 PS190 with the stock 351w HO -- 285hp and 1.52:1 Powerslot. Current prop is the original OJ, which looks to be in good shape but does have a couple nicks on it. I reached out to OJ, and Eric recommends their #454, 13.7 X 17.5 LC 1 1/8” 4-blade. I reached out to ACME, and they recommend their 381.
Anybody with first hand experience on either of these, or have one laying around they'd like to sell?
