Just bought a 2007 Rinker 192SE with Mercruiser 5.0MPI 260HP. It came with 14.5X19 aluminum 3 blade prop. Rinker tech rep tells me it is the correct prop for the boat. I believe I should be getting better performance across the spectrum. The hole shot is OK but but the boat labors to get on plane with a few passengers and a skiier. It's diffucult to keep it on plane below 20mph. The tachometer says RPMs are 5600 and the GPS speed is 50mph at WOT when just me and the wife are on board. It turns a few less RPMs with 3 kids along. Specs say WOT should be between 4600 and 5000 RPMs. I never hit the motor's rev imiter so I assume the tach is incorrect. I want to try a different prop but don't want to hurt the holeshot or hit the rev limiter. Gas consumption is good so far (~5gph) but I have not run it hard for too long yet.
I've been told to do almost everything from adjust the pitch, to add trim tabs, to add a whale tale to the drive, or to add cupping to the current prop. Dealer wants to sell me new prop. He's not much help. Any input will be appreciated.
