    1992 Sport Nautique high temp

    I bought this boat for my niece a couple of years ago. It started running hot and they have had to a couple of local non-Nautique dealers and no one can resolve. Changed out temp gauge, hoses, etc. but problem has not been resolved. They are in NW Wisconsin, live in Minneapolis area. Can anyone suggest a repair shop good with inboards or should we just take it to dealer. Unfortunately, the water has gotten so low on their lake, they haven't been able to launch for 2 years, so they are going to fix and sell. Or if anyone wants to buy it as is, will consider that too! Thanks!

    Impeller? Thermostat? Temperature sending unit?

    If a previous impeller came apart, there could be pieces stuck in cooling passages that can cause high temps.
