Re: 2 blade or 3 blade propeller
I'm a new member. I'm buying a new Marshall Sanderling and am deciding on a two blade vs three blade prop for the 10 hp Nanni 2.10 diesel. Is there more drag with the 3 blade? Is the three blade quieter with less vibration? I am interested in getting max thrust in a tidal outlet to the Atlantic.
That's a small diesel, it certainly will work fine with a suitable size 2 blade. I would doubt they make a 3 blade to deliver so little thrust...
Certified...in several regards...
