Trying to decide on a new prop.

[Angelo23]

Hay fellow Parker owners. I'm trying to decide on a new prop for my F250 Yamaha my parker is a 23 foot walk around. I now have a 3 blade SS with a 17° pitch. At wot I do 38 mph at 5900 rpm this seems to be about right. My problem is at 4700 rpm I only do about 22-24 mph depending on water condition and weight. This seems a little slow to me I am wondering if a four blade prop will help the problem. Appreciate any input. :?:

I was told 4 blade is good for staying on plane and quicker out of the hole. Speed is reduced with 4 blade

38mph top speed seems slow.
Check with your dealer if the prop you have is for a 250.
I had a friend with a slow boat with correct rpms but the prop was for a 200hp.got the right prop and gained 8mph
