Unfortunately I don't know the performance with the old prop because the boat's been set up that way forever... I believe the old prop was likely correctly sized however. I will be trying the 14.5x19p aluminum prop this weekend, and likely buy another 15x17p if the RPM's are lower than they should be.
I'm curious Frank, wouldn't your 14.5x15 prop increase the RPMs over the 14.8x17? Is it the diameter difference that accounts for this instead of the decrease in pitch?
I did go to the Marina yesterday... he wanted $350 for a used Viper 17p and 550+ for a new OEM ss prop. Also went to the marine consignment shop and although there was only one close one (same diam and pitch, but had fairly aggressively cupped edges), or a prop that need a separate hub which he didn't have in stock... I passed on all options. Also checked FB marketplace, ebay, and craigslist. Might buy something locally...
