Model 175TXRR (1993) Yamaha outboard on Grady. Never a problem with many hours of operation in ocean, including past several months. Went out for day, engine ran fine for about 6 hours, with no problems whatsoever.
Brought home, flushed engine, put boat away. Engine left in "down" position on trailer.
Went away for week. Came home, found about 1+ gallon of engine oil on driveway. Oil was running out of carb intakes then down and out of cowling. The main oil reservoir on top is full, to the line. No leaks there. No leaks on any hoses or fittings. Oil was only coming out of the Carb intakes.
Not all of the oil was pumped out of the reserve, and, the main oil tank on top was full. The engine tilt did not work, indicating that the battery had also died, which may explain why not all of the oil was pumped out.
Found that I had left the key "ON" and battery "ON", which I haven't done before. Put charger on battery, with switch and key turned "off".
Reserve tank in bilge area was down more than 1 gallon. Added 1+ gallon oil, hooked-up water, started engine. Wasn't too difficult to start. Of course, lots of smoke. Ran for about 10 minutes. Excessive smoke, and, unburned oil coming out through prop exhaust. Engine was loading up with oil and finally died. Did not want to restart due to unburned oil coming out with water in exhaust and mess to clean up.
I'm pretty sure that this is related to the oil pump but not sure if there is a actually a problem with the pump system itself, or, did leaving the key and battery on simply lead to this problem?
Does this sound like a clean-up (carbs, etc), or, a repair issue (pump, o-ring, etc)? If not too time consuming or difficult, I might do this myself. I'm somewhat mechanically inclined. Otherwise, I could take to a mechanic.
