I have repowered my 21' 1981 Mako with 1998 225 hp two stroke EFI Yamaha...I boat on Lake Erie....I am trying to get some feedback re: what size & pitch I should use on this to get best performance...I am looking for the best size to use to get a good hole shot and not necessarily looking for top end speed, just best economy with the hole shot...I thank anyone that can give some good info on this so I don't have to try many props to get the results I need....Thanks to all.....Big Bill

Can't help on the prop question, but curious where you run on Erie?

We usually run out of Conneaut, OH or Walnut in PA.

Email Ken at Propgods. Tell him the boat, engine, prop and performance of the old engine.
When I changed engines on my 201 he nailed it with a Mercury Enertia. It is a much better prop than the Yamaha I had been using.

When I first got my 21 it had a 98 225 Optimax. It was spinning a 15x19 prop but I was not making top rot so I dropped down to a 15x17 and that brought up my rpms and reduced my fuel burn a little and I actually picked up some speed since the engine could wind up more. The 21 is a deep v hull not a bass boat. It takes a certain amount of forward momentum and speed to get the hull up and out of the water. If you are trying to get a quick hole shot, your just beating on your engine and wasting fuel. I repowered with a 200 Yamaha hpdi and I think that was spinning a 14.75 x 18 prop. I have this all in spread sheets, but I have to find the flash drive with that on it. As for the Propgod...he has a website..look him up. He has helped me too.
