Try calling quality performance marine in corona or a merc only type sevice shop like them, and see if he can register the engine and get it fixed up for you. They MIGHT be able to do that, If any thing it is worth the call. Good luck with it. 735-5503. Was the old impeller bad at all?Anyone have issues with a newer 496?My buddy had his overheat,so he changed the impeller took it out did the same thing, so eddie marine says the housing was bad so new impeller with housing and same thing happens. so 1300 bucks later,now they think its a head gasket issue, motor has 50 hours and is 2 years old.Another problem he bought it from warlock and carter reed so the motor was never registered with merc when sold.So the 3 questions i have is how much to change a set of head gaskets on a 496?Anyone seen carter reed?What are the chances of merc paying for it?
