228 Repower

I don't think you would regret going with yammy or moving to Mercury.

If you get a 4 blade prop you will get better Low speed performance and you will get better lower planning speed, better cruise performance too. You loose top end though.

Well said on both accounts Smoky.
I have a 4.2 Yam and DTS , I love the DTS I could never go back to cable.
 
Not sure you can necessarily go wrong with any of the brands right now. I repowered my 1984 model Seafarer with a Mercury Verado L6 300. I went all digital and have power steering. It's awesome. If you want some videos...let me know.
