    I Just Purchased A 1974 Sleek Craft Jet Boat And Over Hauled The Motor
    New Head Gaskets ,intake Manifold And Gaskets, Exhaust Gaskets
    Pan Gasket Etc. When I Run The Boat Throught The Hose Outside The House The Temp Will Increase From 120 To 220 In About 2 Min
    Changed Thermostat 160 Mabye Ill Try Lake Test Still Same Thing
    I Have Hardin Marin Exhaust My Question Is Can Those Exhaust
    Be Pluged Up From Sitting And Possible Restricting Water Flow
    I Even Pulled The Thermostat Out And Ran It And It Still Got Hot
    Any Answers Would Be Of Help
    Thanks Brando

    is is definitly a water restriction. check your water pump, or the lines. occasionally they get clogged. it may be hard to find, but it'll happen. good luck.
