ocean runner cranking issue

tried starting up my johnson 200hp ocean runner today and the only thing to turn over was the starter. the pendix would turn but the gear would not jump to spin the flywheel. took the pendix apart and oiled with 3n1 oil and moves smooth on the worm gear. checked my voltage on all areas, cleaned all terminals and connections even though they didnt need it and tried to get an extra turn on all connections. could this be a solenoid issue or possibly a kill switch issue

Check battery and grounds.

Re: ocean runner cranking issue

have you load tested your battery?, how long are the battery cables?, DC motors by nature are high current high torque, a starter needs a large amount of current right off the bat to create that sudden impulse to start the pendix gear to jump, any kind of resistance ie...cables to long, corrosion on termination points, Battery terms not tight enough, and yes the solinoid can build up carbon from arching just like old points did, carbon is a primary source of resistance, I would bypass your solinoid take your battery leg staight to the starter becareful not to damage the theads from arching, if no go, load test your battery or try a known good one, or you may just have bad brushes, you may try disaasembling stater examine the brushes if worn replace, if you notice pitted areas in the copper base of the armature unit you can jig it up in a drill press like a lathe and turn it down with a fine file.... to remove pits

yes actually used a brand new battery. two weeks ago she cranked right over. went to work on tug for two weeks, got home and now nothing. ive never had any issues with this motor in the two years ive had it. its very frustrating. im going to try running it straight to the starter from the battery. thanks for all the input

If you let it sit for two weeks you may have something draining your battery.
