  • over heated my motor, please help!

    hiya all
    i have a 115hp. 2 stroke- 1987 model
    got some kelp around my inlet ports today- she got hot- i shut it downbefor the warning buzxzer went off( i dont know if the warning buzzer is working correctly or not)
    i let it cool down, restarted and it started fine and ran fine- but one of the cylinders seemed hotter than the others- so i limped home with the kicker.
    it is the upper cylinder on the starboard side of the boat.
    i did ask the mechanics to do the thermostats when it was in there a few months ago.
    i have only had this motor for a short time and it has run well up till now- but i cant say for sure whether that cylinder was running hotter than the others or not up till now- but it never overheated befor!!
    i flush the motor for about 20 mins after everytime i have it in the water.
    i know this is an old motor- but it is the only one i have-
    is it save-able??
    many thanks

    For one cylinder to run hotter than the rest, that cylinder is either running more lean or there is a blockage. You may need to replace the water pump impeller.
