Re: 1974 Evinrude Yachtwin 4hp – failing to start

I’ll check the spark plug wires and run a compression test.

There was some history here on the old boards of this motor, but its gone now, so I will recap.

I got this motor with a sailboat I bought some time ago. It’s probably the one motor that got me involved in the old outboards as I started getting advice here. Anyhow, I got the motor in Connecticut, and brought it to Florida (Port Charlotte) with the sailboat. Didn’t realize how shallow Charlotte Harbor can be in places and promptly ran it into the ground, breaking shear pins etc. Got the motor repaired down there and brought it home.

After consultation with the fine members of AOMCI I got the motor running again, but on open water tests it was overheating badly. General advice was that there was probably something jamming the water passages in the head, and a head removal/cleanout was in order. I did this, and did find a few passages that were blocked with dried mud/salt. I cleaned the passages and put the motor back together.

I’m pretty sure I ran the motor in a barrel at home, just a quick startup. But this was a year ago +. I do know that when I put the coil start puller back together, it now seems to pull and retrieve somewhat slower. I tried pulling the motor over with a rope on top as it was spinning it faster then, but no luck.

So, Ill check the plug wires and the compression and may pull the flywheel to look at the points and check them. See if I can get her popping over again. Ill let you know.
