prop for 23' Sceptre

[Bushwacker]

Sounds like you might want to get that tach checked before doing any prop trials! Doesn't sound like computer will let it wind up that fast!

You might want to consider a 4 blade stern lifting prop. When I added bracket (and a new 427 lb motor), boat would NOT plane below about 18-20 mph with a 3 blade prop! With the old 300 lb motor hung on transom, I could easily plane at 12 mph. Now with a 4-blade prop, it will again plane at 12 mph no sweat, even with a very heavy load!
