Overheating 1984 DT75

[CalebWindham]

New to iBoats!
Thanks in advance for the help!!
I have a 1984 15' Skeeter Strada with a 84 Suzuki DT75 as my power plant.
The motor is throwing the temperature sensor at higher rpms. When I plain the boat the sensor will sound the alarm. I changed the impeller, thermostat and temperature sensor today, I took it to the lake and the new sensor sounded the alarm. I noticed the telltale discharge had a little steam today when the alarm sounded. I kill the motor at the first sound of the alarm each time to prevent further damage. Could this be a head gasket? I plan on doing a compression test and spark plug check tomorrow. I understand it could be blockage of water passages even though the telltale stream is VERY strong. What are the best ways to clean these passages?
Any other advice???


The fishing condition down here on the gulf of Mississippi are going to be ideal next week! Hope to be on the water tearing them up!!!

You definitely meed to use a different Font, that is hard on these old eyes.
You can try salt away or a few other products, but may need to pull and manually clean passages
