I recently bought a 1994 Johnson 65 Jet Serial # 3888196 outboard that doesn't seem to be pumping water at least there is no water coming out of the smal port located on the bottom of the motor, left side. Should this port be pushing water all the time? Whe I was running the motor, it didn't seem to be geting hot? <br /><br />My questions are as follows:<br /><br />Should it be pumping water out of that port, or does the water get expelled elsewhere?<br /><br />Does this motor have a thermostat? If so Where is it located?<br /><br />Is the impeller difficult to change? <br /><br />Any help is appreciated.<br /><br />Fishburn
