Johnson 48 hp spl hard to turnover

[wodalton]

Hello,<br />My 1988 Johnson failed Sunday. I was running <br />real slow and it clunked (sorry for the term)<br />and quit. I tried to crank it and it would<br />not even turn over. I had to keep bumping the <br />starter for it to get to a point so it would <br />turn over. It would then start but would not <br />go when put in gear. I then had to bump it many times again to get it to even turnover. Finally,<br />got to start again and limped back to dock very<br />slowly. At home, I changed plugs and battery, still it will not turn over. I have to bump the <br />starter and then after several tries it does try <br />to run but dies. Any Clues?

Sounds like your engine is trying to seize.<br /><br />Cooling?<br /><br />Sufficient lubrication?<br /><br />Maybe you also have a connection problem in the large guage wires for your starter.<br /><br />Good luck.

Hello,<br />I put the called amount of oil in (50:1)<br />when I last got gas. When I finally got it to <br />restart Sunday water was coming out of the jet<br />so I assumed it was fine. What you say sounds<br />close, it sounds like its trying to seize.<br /><br />What can I do?

Sounds like it's overheating. Change the impeller in your water pump. Run a tank of 32:1 or 40:1 through it then go back to 50:1. I think this might cure it's "seizures".
