Here's the deal.
My project 65hp T-Crate came with a Senci 74-46
The tip has a little damage so I'm going to cut off an inch to become a 72".
My motor has larger venturi, jets & timing change.
Would like to think it's in the 75hp range at 2,400rpm.
I'm want to put on Lotus floats in the spring (no it's not in a Certified class) but it's on ski's right now.
I swapped a 74-42 McCauly onto it to try.
It's a sweetheart with the 74-42 on it, in fact I'm thinkin it almost doesn't have enough pitch. It really climbs out at 2450rpm but you have to watch the throttle to keep the revs under control. I'm thinkin a 74-43 would be about perfect for a seaplane prop for it, then again...maybe it won't pull as hard come warm summer months
Can one directly compare Sense props to McCauly as far as pitch & performance goes?
Since I'm trimming the Sensi to 72" should I add another inch to the pitch eg 72-44 to equal the performance of a 74-43 when I get it repitched?
Just how much does 2" overall length affect pitch required?
I guess one will always second guess decisions like this but it sure can't help to hear from those with MUCH more experience than I!
