    Need opinions on Electramatic

    Johnson RK-28B, 40hp Electramatic (1966) J2651698 Finally splashed the boat today, after 3 years of working on it. Grinning ear to ear. But (you knew that was coming, right?), at about half-throttle the prop-hub spun, or at least I hope that it did. Could not get the boat up on plane. If I...

    Best Father's Day gift ever!

    After 3 years of work, as yet un-calculated total cost, and a lot of "I'll never finish this", today is the day I finally get to splash my boat :D Told my wife yesterday to take a good long look at it, 'cause this time tomorrow it might be at the bottom of the lake! And I may just go down with...

    How do 'ya think this would work?

    Not really needing help here, just thought ya'll might find this interesting.... Started the rewire today, and was taking a good looooong look at the diagram in the manuel (yes, it is the Johnson, on cd-rom) Chasing those black lines to see if what I have matches up; it'll make you cross-eyed...

    Any body recognize this?

    Ok, so this is what the thing looked like when I brought it home 3 years ago. Only 'before' picture I have. Looks much better now, I'll post new pictures later.... Have no idea what it is, the top half of transom plate is broke off, all that's left is weight/hp rating. Have not registered it...

    j4c vs. j8c ??

    Ok, so call me late to the game. Have a Johnson RK-28B 40 hp Electramatic (1966). While perusing the parts manuel this morning, I discovered my engine calls for Champion J4C sparkplugs. When I got the motor it had, and still has, J8C plugs in it. I have had the motor running fine w/the 8's (in a...

    Bow bracket for the cover??

    Gotta little 14' fiberglass, 60" wide, v-hull. Bought the smallest cover I could find (on clearance!). It fits fairly good, but of course it sags in the center. I have seen people make a 'tent' for their boats out of PVC pipe and tarps. Thought about using the PVC to make two bows to hold up the...

    Measuring old style prop

    I have a Johnson Super Seahorse 40hp, RK-28B (1966) The original prop is spun. I can turn the inner hub by hand. I have another prop from ebay, have not had it in the water yet. The leading edges are pretty dinged up. I intend to call a couple prop shops about repairing the spun one...

    Johnson flooded out

    Ok, so I wrote yesterday about torquing the flywheel nut. Got that done with no problem. Ol' gal fired right up and ran as well as I expected for being in a drum. Using the control box, I ran it in forward and reverse (elec. shift) at a little less than half throttle. It would idle resonably...
