OMC Year Lookup request?

[johnbo]

Hi,

Could someone who has access to the magic lookup table tell me which year the OMC Cobra with the following nameplate is from? Basically which manual would I need for this?

Model: 986700 5.0L
Serial: T0739759

The reason that I'm asking is that I was looking at a OMC Stern Drive manual, but it shows a list of applicable model numbers that all seem to point at a model number of 987346.

I know that some part of this outdrive was placed at one point, due to a submerged stump.

Thanks and have a happy fourth.,

johnbo

Those are not your model numbers. Might check the sterndrive section of the link below and see if you can find your model number.

See if you can pull the model # off the engine, should be a plate on the thermostat housing with engine model/ser info.

Thanks for the link. I did find the sticker on the valve cover. It appears that my buddy has a 1991 drive in his boat. Not a big surprise.

I've found a manual for a 93, but it doesn't explicitly cover a 91.

Two questions

1) Anyone want to say how close a 91 and 93 drive would be? (502BPRRGD('91) vs 502BPRJVB('93))

2) Are there any chance of finding a OMC dealer that would still carry these old manuals. Or is there a better source than eBay?

Thanks,
johnbo

OEM manuals only cover a specific year rather than a range, they are probably close but I would still try for the correct one if you can. You can find quite a few on eBay but you can try this guy OMC Manuals or you should be able to get one for sure at Ken Cook Manuals

Bob,

Thanks for the links, I'm chasing down the prices on one of the sites right now. I did end up buying the wrong year manual, just because it was so cheap and I need to get started on this.

I printed copies of the relevant pages of the DougRussell parts diagrams from both years and will use these as a half-hearted attempt at a 'difference' document. I'm ASSUMING that the majority of the process is still the same.

Thanks,
johnbo
