I hear that Ferman, that is the cause of a lot of P/H failures of all brands, truth be told. You know Bajamerc/ Kevin from the deisel forums. He is the owner of the tunnel boat mentioned. He and his brother put an E-tec on a short 15" midsection and grafted a sportmaster to it. The Lake Tarpon Boys gotta E-tec fetish. LOL He can still turn the RPM, the boat is a lot lighter so he isn't really taxing the motor and lugging it per se. He just wants to be able to cruise 80 at 4000 rpm and go all day on 25 gals of fuel. Currently averaging 6 MPG as I understand it..
Plus he added I-command gauges.. Which I like better than the SmartCraft..
