Bill,
Let me know how the hose works out. I sure like to color scheme green with red, pretty cool. Doug Brooke

Finally finished, running restoration. Took me a lot of work to save this one.

This, the next project, a Duratech S-14 will have the KG-9 as power source. Going to build a center deck and add steering.

Running on the river in September. This thing runs like a watch, starts on the 2nd pull cold and 1st pull hot.

Question.

Looks like you upgraded to newer style rods vs. the older 3-hole versions. When I did this on a MK50 build years ago, I found I needed to use the original rod nut & bolt for clearance reasons. Did you have similar issues here? I have a KG-9 in a box and one of the things that scares me is the primitive mag internals. You really put some serious work in there. Wow.

Also, were you able to source a new seal and/or bearing for the end of the mag drive housing that is cast into the crankcase cover? Looks like the seal on mine was shot and the grease from the gear box oozzed on top of the mag body...

Answer to your question; YES! it can and it was. Good job with great results!
Let's fix it now - before we launch the boat.

I didn't have any clearance problems on this motor except for a small area in the block on the edge of the area near the bore on the exhaust side where rods pass by, i used a rotary ball file and removed about a scoche of the aluminum there. Didn't have to alter the bolts. HOWEVER, on my prehistoric KF-9 this area is even tighter and on that one I not only clearanced the block on both sides but beveled the heads of the rod bolts as well. KG-9 and MK40 rods have more primitive rod bolts with taller hex heads, they were beveled from Mercury. I can't recall fully but I'm pretty sure the rods in old # 22 were ALLEN HEAD like a KE-7! IMHO, the rods with holes weak point is the cut for the bolt

As for the magneto issues, the needle bearing in the magneto end of the mag tower is a GB1012, the seal is a # 6151, there's a picture of all the boxes in the greasy junk thread concurrent with this one. Also a table in white papers with prices and sources I used. Error on my part, I started with a B912 and had to centerless grind it on a dowel until it fit! Order the GB = "Ground Bearing".

Best leave the bearing races in the mag and frame cap, they are installed with PAPER SHIMS! I dug thru a friends TOTE BIN full of FM stuff and none of it matched. I made new cork seals out of gasket sheet to replace the totally deteriorated originals.

Thanks!

I vaguely remember seeing a service bulletin from Mercury with regard to upgrading older style rods and reserving the old bolts, but can't remember where.
