When I bought the Vashon, she had a 16x12 four blade Nibral prop, which I replaced with a 16x10 three blade. WOT RPM specs for my MD2030 Volvo is 3200-3600 and I was at 3150 RPM. Over the months, barnacles, running gear fouling, and added weight dropped my WOT RPM to around 3000 RPM. I installed a new three blade 16x8 high thrust prop and RPM at WOT is now around 3400 or so (within Volvo's specs). Mechanic noted that I have a large prop shaft (1.25" diameter) for my trawler's size.
Also added a manual "emergency" pump as a back-up to my two electric bilge pumps and the bottom was pressure washed.
I will be taking Sherpa on a cruise to Tarpon Springs next month so I wanted this addressed beforehand.
