Greetings my friends. Can anyone tell me how to test the temp probe on my project ski.Its running good except overheating in water. Have been taking breaks letting it cool down. I may modify an all stainless or is it aluminum tuned pipe I got from ebay. modifying to fit. We burned through the short hose in rear of exhaust. went to home depot today. I used the split rubber hose with a metal peace of exhaust pipe for 2 weeks of rideing on the patapisco River. I have been doing lots of experimental stuff to add cooling water flow and have learned alot. Please someone make me feel welcome here and give me a quick answer to fkrst question? thank you.
