I have a Johnson 1960 75 horsepower outboard. I rebuilt the entire engine over the winter. Pistons rings gasket seals etc. Started it up a couple of weeks ago and it seemed to be okay although I didn't have time to adjust the carburetors. I went to start it up today and the starter doesn't seem to turn the engine over fast enough to get it started. I Checked all of the connections and and the voltage at the battery and everything seems to be fine. The starter is original and I did not rebuild it. What direction should I be looking? Brushes? Also, why would they even put a pull starter on a motor like this. I can turn it over easily if I don't have the plugs in. Once I put the plugs in it's almost impossible to turn over.

Well----1960 was a different era.----Electric start was " expensive "--Many folks were able to start those 75 HP motors with the recoil !!!------I remember stating a 1966 model 100 HP Johnson one weekend with rope around the flywheel.----Electric starter was broken.----Heck not to long ago they marketed a 125 HP " commercial " motor with a manual starter.

Try jumping it from your truck or car. If it cranks well, the problem is likely your battery, However, a good cleaning of the starter and perhaps new brushes can work wonders.

Sandpaper all connections until bright. When jumping, connect the pos cable to the lug on the side of the starter, neg to the starter bracket.
