Got a pretty basic outboard with a jon boat I just bought. Was told it is a 7.5 hp Sears (wizard) outboard. Put it in a bucket and the motor ran fine. Never saw any water coem out of two ports have way up the shaft- only exhaust. Any way to tell if this is a water cooled motor or air cooled? If it is water cooled, where is the pump? Also, any intel on locating a service manual would be helpful. Thanks |

There should be fins on the block like an air cooled lawnmower engine.I have a 5hp air cooled j9 clinton. |

There is a water pump in the lower unit for cooling the lower unit. I replaced mine.Still didn't see much difference after.Read here that with most sears engines very little mist will be seen, and most of these engines only pump water when in gear.My impeller was missing two fins, so it needed replacing, but i also had a gasket leaking under engine(deflector plate) so I figured that was why i wasn't seeing water at the exhaust ports like I should.Water was comming out on bottom of engine at that little port so i guess the pump was working.Good Luck.. |
