Thread: Not getting listed max rpm

Yes

On 2 standards I get 57-5800 and performance I get 6000-6200 depending on trim.

Cray, why do you suggest a 3 blade over 4? Most toons I've helped power we have put 4 blades on for more lift and better steering at slower speeds. Helps with steering at idle speeds too. Is there something good I'm missing with the 3 blade?

I was speaking more to your oil temp, especially if you have 25w40 in there.

I've been looking at that for a bit shows that all the time . Might not have a oil tem sensor..

The only thing I could see not using 4 is in reverse as the more blades less control going backwards.

call power tech props. They will fix you up
