Hello
Thanks in advance for reading and possibly assisting in some advice.
I have a '84 70 hp evinrude my grandfather used to own, I've used it for two seasons now. The first season, it had been sitting a bit, so I cleaned all the carbs with fishing line, replaced plugs, gear oil, new battery, adjusted cables. The engine always started and ran fine, a little sluggish from idle to WOT, but considered that normal for the age of the engine.
Season 3 - changed out gear oil, got to the lake and started and ran normally for about 3 hours. Nearing the end of our day, near the ramp, the engine just quit. I checked the gas tank it was on, and it was basically empty. Attached the second full can of gas and tried to start. It didn't even sound right. The starter would push the flywheel one revolution and then stop. Sometimes, if holding the ignition key to start, I would get one revolution, pause, and maybe a second. Got a friendly tow the last 200 yards to the ramp.
Pulled the battery and had it checked - store analyzer stated it was bad, so got a fresh battery. Hooked it up, same problem. When I tried to manually start the engine with a pull rope, it seemed very hard to pull, but I could give it a spin. Again, after one spin, it would stop. The flywheel seemed very hard to turn, but I never tried manually turning the flywheel before.
Searching websites, reading manuals, etc. Would just like any feedback. My fear is the lower unit is seized (prop spins easily, so no entanglement there) or one of the coils under the flywheel is bad. No warning, though. My understanding is that one coil starts the flywheel/driveshaft spinning, then the other coils take over during ignition. I really don't think it is the starter, but that seems to me the next logical thing to test/replace. Thanks for any advice.
