it will match only the ancient mercury's had a different bolt pattern and i think it was nmma that set the standard. i might be wrong.

When I dumped the 99 ficht and bolted up the Merc . . . everything bolted up just fine!!
I never regretted it for one second.

And the FORCE engines used a different pattern as well. But who would run one of those?

Thanks! for the info I am planning on talking to them today and figure it out.

yeah no lie..those were the cheapest made engines i ever worked on.

If you do them yourself and do the epoxy wood dowel set up make sure you use hardwood dowels, not soft wood. One fellow I know did his with soft wood thinking it would not make a difference, they crumbled apart after a couple of seasons and destroyed his transom.
While you have the engine off go thru all current and prvious screw holes and reseal them too.
