I installed the 2419 prop on my Supra SC350 and was delighted with the results.
Acme 2419: 15" dia X 12" pitch
It only has about an inch of clearance from the hull but three is no gel burn or negative effects.
Before I had the 2079 which was an improvement over the ACME 1235 (stock prop), but it cannot compare to the 2419.
