Im having issues now with engine overheating. I replaced the waterpump impeller a year or two ago and it seems to still be working since is squirting water out and all of that. It heats up when going through no wake zones at low speeds and the gauge reads 3/4 when at full throttle/plane going down the lake. It used to stay at 1/2 on the temp gauge whether at full speed or not...i'm' stumped as to what it could be. Before i replaced the impeller it would overheat when going at low speed or if it idled for a while but go back to the half way point when at full speed. Help?
