Motor probably needs a stainless impeller to put down the power. The used aluminium has trouble handling the power, that and it was sharpened bass ackwards when we bought it. It wil launch with a stainless and I think it will be around 38mph on the lake when it's put together with a stainless. I had it up to 37mph on the lake last year once we'd broke the motor in. We can probably put a stainless in it and let you see how it'll run with it if you come to look at it. He's just been thinking about selling it for a while and didn't want to buy the stainless right before he sold it.
