Mercury Through The Years...

We had an older motor without that provision (might have been a 44ci Merc 400). We made an adapter plate from plate aluminum. Worked great for about a year but then the driveshaft splines started to fail. That adapter caused the driveshaft splines to not engage fully so Brooke Russell sleeved and pinned a slightly longer top end on the shaft. Over the years I suffered just about every common failure from breaking off the top of a crank to breaking out the rear bearing carrier in the lower unit and most of the stuff in between. I learned a lot and with the help of a few knowledgeable friends I got so I could make the 500s run pretty good and pretty reliable too.

Heres just a pretty picture of mine - now being replaced by a 650XS.Attachment 376464

That's nice. A real classic.
I will have to admit that I probably made every tuning and setup mistake in the book on those motors. Hell,I probably added a couple to the book but it was all a learning experience and great fun.

I have driven several 15' Checkmates with J motors and if you can manage a 14 with one you have my admiration.

It actually is a 1968 131, 13'. Orignally owned by the Kiekhaefer Corporation, and was a playtoy of Freddy hisself. Fred verified that for me when he recognized the deck mounted tach tube and the forerunners to K-Planes, built by JD Emerson at the Lake - which is cool because I know JD also. Fred sent me a "Dialed in at Lake X" decal, its on the dash. It says "dialed in at Lake X" and then is autographed "by Fred Kiekhaefer". During my resto process I found the Attachment 376469Attachment 376470Attachment 376471Attachment 376472Kiekhaefer Corp property tags for the boat and trailer! The seats I had reupholstered but that back tank cover is original upholstery! Also has early tilt wheel Ride Guide! I did respray the deck but the rest was just buffed up. Bottom has about 3 feet of SuperGlide at the keel. Getting close to trying it with the 650XS, some rigging to finish. Check out those original 50 year old transom bolts!

A word of warning. Those MX13s did not play well with the 650 lower units. Lots of prop blowout. I found them to handle better with the big units on the 850s in G class. I got my 13' Action cheap because the first owner spun it several times and scared himself. I managed to make it better but every once in a while it would try to go sideways.

I had that motor as well, strong and great looking. Turned a two blade, seems strange now.

Maybe thats why there is a fin on one of the tabs? The boat had something bigger on it at some point in time, found big bracket bolt holes and a PT harness tucked away under the gunnel. I will work into the XS with caution. Thanks!
