I have this really nice Pontoon boat with a Yamaha 50hp motor on it. Or rather my wife does, I have a bass boat. The boat is not real fast and not sure if it will pull grandkids on a big tube or something like that. I have inspected the prop several times and there are no numbers stamped on it...
I have a Johnson 115hp Sea Horse, either a 1978 or 79 model. I'm fixing to change the plugs and nned to find out the correct gap for the plugs.:confused::confused:
