Treasure Coast Propeller came highly reccomended. I now have to highly reccomend them. Finally after the trip and then our storms got to do the performance sea trial last Saturday. We made 2370 and 2380 RPMs WOT. Seems to be a bit higher on cruise speed but need more time to decide if that is real or in my head. But given the factor of M-15's high speed spinning the wheels, going from 3 to 4 blade, and old school hull they nailed these on size, pitch, and cup to make the transition. Boat planes off great and one of the biggest benefits is much less loss of speed going against the current on plane. End of the day no need to take them back for tuning (included in purchase price if needed).
Also the sea trial was not without other events. After reaching full RPM long enough to take valid temp readings (turned out perfect) port engine lost RPM and eventually stalled after rolling coal. Tried to start but each time only ran for a couple seconds at very low RPM and then stalled again. Limped back to the dock and discussed possibilities of what could be wrong. Flapper was open so mechanic was guessing fuel pump or maybe blower not turning. But back at the dock he started with basics to rule them out. Used a pump to prime the injectors to try a restart. Wasn't building pressure. Turned out to just be a leak at a loose fitting so injectors were not getting proper pressure. Got us up and running.
So shout out to Paul at TC propeller and Wayne at Anclote Diesel. These are the go to guys for sure.
