Cool Chuck. I love a simple problem. I try real hard to keep my 4 hp 4 stroke functioning well and keep a mental file of what fixed various problems. I am a technical trainer for a company that manufactures automotive training aides and a retired automotive electronics instructor and have seen many really tough and strange problems, so it is great to see a simple fix that works.
I had an interesting encounter yesterday regarding my old motor. During the summer I am in a marina that is pretty tight, so the owner requires that motor NOT be left tilted out of the water. So for years my motor has sat in the relatively stagnant water. The cover is really sun faded, and the lower end has stains from the water BUT, it runs well. I have done all the maintenance on it including synthetic oil, plugs, water pumps, etc and I only use non-ethanol fuel. As I was flushing the salt water out of the motor, someone, that I do not know walked up with his dog. He looked at the boat, looked at the motor and announced that he would not go out into the Gulf with a motor that looked that bad. And this is while the motor is purring along at a fast idle. I decided to NOT let him hear a word out of me and continued to wash the salt off the hull. After letting his dog pee on my trailer tire, he walked off. Surrounded by experts, I somehow continue to sail without killing myself. Just luck, I guess. LOL
Have a great sailing season and Sail On.... Al
