Re: Video of 1957 35 hp please help

[Monte NZ]

After reading all the posts and watching and playing the video several times, during which I listened very carefully to the sound of the motor, I feel too, that the motor was seizing at the end of the video. I feel too, that it’s got to be lack of lubrication or a cooling problem.

I had the misfortune to have my 1963 40hp Big Twin seize years back. This was caused because the young chap at the garage forgot to put any oil in the tank. As luck would have it, it was the only time I had not done the fueling up myself. The sound the video brought back unhappy memories of that experience…….the sounds on the video are very familiar!

One thing I did and you might like to do, is to put a small torch bulb soldered to some fine wire, down through each of the spark plugs and slowly turn the flywheel. It won’t cure anything, but I found it helpful in showing the damage to the bore.

In the OMC workshop manuals they mention using Thermomelt sticks to check if the motor was operating at the correct temperature…….it might be worth giving them a go……..I have used them successfully.
