    1981 OMC 800 Reverse Gear and Prop Shaft

    All, I am replacing the clutch dog and reverse gear on my 800. Two questions: 1. Are OMC part numbers unique to themselves? 2. Both the new and old reverse gears ride loosely on the prop shaft. I would expect there to a bearing system between the prop and gear. How does the reverse...

    OMC 800 Shift Detent Spring and Balls

    I am replacing the clutch dog on my 1981 OMC 800. The Seloc manual I am following indicates that some models (1978-1981) did not include a detent spring and balls in the shift shaft. My assembly does not have them. Why would I not have them in mine? Why the alternative?

    Low Voltage Charging and Hot Wires

    Boat Brains, I am troubleshooting why my boat is not getting 13.4V at the alternator. I ruined a battery last year that got really hot and would barely turn over the 1981 5.7L/350CID/OMC260. That may have been because of the wires from the Battery Pos to the Starter Lug that went through a...

    Alternator Rebuild

    All, I have a marine alternator that I have disassembled and am replacing a potentially bad rectifier. I found one, but also purchased an auto alternator to see what the difference is and if I could use parts from it. From what I see, there is not a difference on the internal parts, just the...

    External to Internal Voltage Regulation

    All, I have an alternator and regulator that may need to be replaced. Can, or should, I replace it with an alternator with an internal regulator? Something like this? http://bpi.ebasicpower.com/mm5/merchant.mvc?Screen=PROD&Store_Code=eBasicPower&Product_Code=MES3140M-D&Category_Code=OMC9B Jason

    Rochester Carb Needs Help to Low Idle

    All, I had my new rebuilt carb professionally cleaned this winter in an effort to chase another problem. However there still is another issue with the performance of the carb. This issue existed before it was cleaned. I ran the boat to sufficiently warm to where it should idle down around...

    Steamy, wet oil inside of Valve Covers

    All, My 1981 OMC 260/800 sterndrive has steamy oil. After about having the boat out a month last summer, I noticed steam and coagulated oil inside of the valve covers and the vent tubes that go to the carb. The thing is that it runs really well. However, I am taking on water somehow. It was...

    OMC Shift Assembly Housing Recabling

    All, I have a 1981 OMC 800 Sterndrive. I had to cut the old shift cable out and get a new one as part of a rebuild. Taking out the cut cable was easy. Getting it back in is more involved. I have looked at the manual and it cautions me from disassembling this housing and to seek a qualified...

    1981 OMC 800 Shift Cable

    All, I am in need of a 1981 OMC 800 Sterndrive Shift Cable. This drive has a power assist servo and the OMC # on the cable is 982795. I purchased an OMC 982802 and the shielding appears the same, but the cable lengths are different. Maybe I could have someone modify this cable. TIA...
