    18 hp Johnson no spark

    Thanks everybody for your replies. I did install new condensers. I've worked on many motors and can't recall a case where the condensers were bad (lucky?) but I replaced them anyway. Still no spark. I remembered other motors where the ignition wires had deteriorated at the spark plug boot...

    18 hp Johnson no spark

    I recently inherited a 1960 Johnson 18 hp outboard. I've worked on dozens of motors (though I'm not a certified outboard mechanic) and never had the following problem. The motor has no spark. I've replaced the coils, points clean and adjusted. I lightly sanded the top of the shaft and the...

    Thanks; starting to think I was going crazy. I'll run in on the lake and let you know. thanks again!

    1970 4 hp Evinrude stops suddenly

    Was up and running and running very cool in the barrel. You could put your hand on the head. This was without the prop. After I put the prop on and ran it the head was very hot (sizzled when I sprinkled water on it). I haven't taken the temp of the block yet but the head is very hot. ???

    70 4 hp Evinrude recoil

    Thanks! I'll give it a try (probably more than one). I know exactly what you mean about the washer

    70 4 hp Evinrude recoil

    Just finished replacing the exhaust cover. I should have left the recoil and just loosened it a bit and slid the exhaust cover (if that's possible). Anyway I'm looking about 6 feet of unwound spring; the rest still there. A while back I did replace the cord without any problem as I didn't have...

    1970 4 hp Evinrude stops suddenly

    Thanks everyone! It's up and running and cooling nicely now. At first I though it must be some other problem as it was still overheating. I did notice that (in the barrel) a lot of water that stayed cold was coming out the leg holes even though the block/head were getting extremely hot. I...

    1970 4 hp Evinrude stops suddenly

    No I didn't drill it out. I twisted a drill bit by hand just to clean out the buildup.

    1970 4 hp Evinrude stops suddenly

    Anybody think it could be what I described; the plugged coolant flow exit for the cooling water at the (hole) at the top of the exhaust? Will let you know as soon as I replace the gasket and fire it up. thanks

    1970 4 hp Evinrude stops suddenly

    Pipe is clear as I ran a stainless wire through it. There is no rubber boot at the block. It has a threaded 'compression fitting.' Inlet clean and deep in the barrel. thanks

    1970 4 hp Evinrude stops suddenly

    Forgot to mention: Odd thing is that the chamber and the head and areas beyond are all clean and there is no corrosion. Don't understand how this hole would be plugged (though it is small). Don't know engineering but you would think they would have had a larger hole unless they wanted the...

    1970 4 hp Evinrude stops suddenly

    Been a while but with winter this motor was one of my projects. I pulled the exhaust cover and found that the small hole at the top of the 'cooling' chamber was plugged; with what I don't know but I would describe it as brown ceramic/mud. Really hard. I ground it out and now it should be...

    58 Evinrude 7.5 tiller adjustment

    It's my go to motor; that it or my 1962 Johnson 10 that I use on my local lake with a 10 hp limit. I bought it for $25 and it was only used by a duck hunter; not much use. I recently replaced the impeller; pain since you have to remove the power head but well worth it. You're right; a great...

    Supreme Mariner: Thank you also! Don't know what I would do without you and Racerone.

    58 Evinrude 7.5 tiller adjustment

    Racerone: Thanks! Took the motor out of the test tank and it was just where you described it. Thought it was an odd place but it is what it is. Thanks!

    58 Evinrude 7.5 tiller adjustment

    Doesn't look like there's a tension screw. The motor has had very little use and I can't find where it may have fallen off from. I'm hoping it has one.
