About 5 years ago I repowered with a Yanmar 3YM30AE which is a 30 HP engine and weighs much less and is quieter than than the previous 3HMF. I changed to a 3-blade fixed prop (16 x 13) and it is a good match. I would make the same change all over again if I was faced with the same situation. Good luck!
