Going to walk you through the events and symptoms to see if maybe any one has any ideas what is wrong. My buddy and I are at a loss.
We got a 1983 grady white with a 2003 evinrude 250 last year. The boat was bullet proof with zero issues except some times after running it then turning the engine off, the engine would not turn over. We had power but nothing would crank. We would wait a few minutes and jiggle the throttle, thinking it was neutral kill switch, and it would eventually start and run great. We lived with this for most of the season.
In June, I was running home from surfing and while cruising at 4300 rpm the engine shut off. There was no misfire or anything. The engine then would not start and same as before, if we waited and jiggled the throttle it would start, except this time the issue occurred while under power.
This is where it gets bad, the following we weekend we took the boat out in some rough waters and the engine shut off under power. No misfires or weird sounds, just shut off smoothly. We then had issues getting the boat in gear and it was running strange. Upon getting back to the dock we realized we had sheered the upper control arm bolts!!! WE GOT VERY LUCKY!
So for the last 3 months we have pulled the power head, replaced the upper control bolts, also replaced the lower crank shaft seal because we had a minor leak. We then re-installed to spec from the manual. We then also had to re-bend the shift rod because it had been bent from the angle of the outboard with out the upper control bolts. Upon further investigation we found the metal plate where the shift linkage is welded too had broke. So we welded that back on. After some adjustment of shifter linkage it was shifting.
Digging around on the forums we found these engines are known for issues with a relay that can cause the symptoms we are seeing. So we replaced all 4 relays to be safe.
And so finally after being out of the water for the majority of the fishing season we finally got her back in the water. She ran great and sounded amazing. However, we had the same issue. We would have to wait approximately 5-10 minutes and jiggle the shifter after turning the engine off to restart the engine.
After pulling the boat out we checked the neutral kill switch for power and it had voltage. Weirdly though, if we unplugged the neutral kill switch the engine would not turn over while in gear. I would think it should turn over if it is not plugged in?
What else should we look into? Computer issues? Should we get a computer reader?
Thanks
