Anyone have info on a red & white 1991 33' Powerplay from South Haven MI area. 650hp blower motors?

It sounds like you're describing Greg's 1990 33' Power Play. Not sure if he owns it anymore. He actually boated out of St. Joseph, MI. Doctor Dave built the 565" engines with Stainless exhaust manifolds. The engines probably make a little more than 650hp---I think it's more like 750-800hp. That thing hauls the mail! I considered it before I bought my A/T.

Doctor Dave knows that boat inside and out. You can call him at 269-944-0214

Thanks for the phone # I will give him a call. Anyone know the value of this Powerplay???

Give the factory a call...Ask for "Gar"...Very knowledgable guy & will help you with the value on that Powerplay. He's helped me before. Their number is 954-733-2500.
