    Johnson 70EL76D Terminal Block Wiring

    Yes. Yes they do. Might also be all the Marine Seafoam that has been going thru it before I got it. He told me he put some in every tank. Even the head domes were spit polished.

    That is what I was expecting given the low compression readings. Thanks.

    Johnson 70EL76D Terminal Block Wiring

    I have scoped the cylinders and was expecting a bit more carnage than I found. But then again, I only have a frame of reference from 4 stroke industrial and automotive. Perhaps these marine 2 strokes are more intolerant. That's where I need an experienced eye. I have uploaded photos for: Cyl...

    That may be the next step. I am going to scope the cyls and check the walls for damage. If they are scored, someone else gets a parts motor. I'm not up for a rebuild. I've been toying around with the idea of a 4 stroke replacement anyway.

    I can see it now that you pointed it out. I did not notice it before. Had to blow up the pic. Poor eyesight and poor lighting in the shop are getting worse. Thanks for that though. So the wiring is not an issue. I will have to put it all back together and test the compression again. I don't...

    Johnson 70EL76D Terminal Block Wiring

    Sorry for my ignorance. Please elaborate on the "Jumper". I am not seeing any jumper wire. Motor has been great for years. I checked compression, as did the mechanic, and all three pass spec within a pound or two of each other. Water intrusion... What am I looking for?

    Johnson 70EL76D Terminal Block Wiring

    I have a '76 Johnson 70HP (70EL76D) that I inherited. It has been running for years with only a slight hesitation on WOT from neutral. Last season, it got worse to the point that the hesitation was permanent and it would not achieve more than 6 or 7 mph. I replaced the plugs and all 3 coils with...
