Johnson will only run with timer base disengaged

Interesting flywheel holding tool. This is a pic.of what I use. Not expensive.

Impact is a great convenience. When I took two flywheels off a couple of months ago, I had no trouble with an adjustable wrench. Didn't buy the socket until it was time to put it back.

And who knows about the history on the crank threads I saw come off - just remember making a fair number of runs to the local machine shop to get them fixed back in '84 and '85. Never seen it on the net though.

Thanks. I got a $7 piece of angled steel and welded her up. Some guy on here made fun of my weld, but it has held up the 3-4 times I have used it. I like your tool better, but when I needed it it would have taken too long to get here.

I have always used an impact wrench to get my flywheel nuts off. Sounds like it is all up to opinion at this point. I use the impact wrench every chance I can get (only with removal for most tasks). Sure has saved me some aches and pains.

Well, the flywheel key was not the issue at all. Removed the flywheel and found it to be intact. Followed what testing procedures I could (from service manual) with my multimeter and found the timer base to be faulty. Found one at Van's Outboards in Grand Rapids, Michigan. Installed it and engine runs like a top. Can't believe how low I can get her to idle now that the timing is adjusting (and retarding at idle like it is supposed to). Thanks again for all your help.

Good for you. Those were the tests I had mentionEd in the beginning but racers key suggestion did make the most since. Posting this in case someone comes along years from now.

interesting to see reference to Vans Outboards too. Good folks -- been there a long time.

I know this is an old post but I had forgotten that I had posted it. Including the conclusion here in case somebody else has has this same problem and finds this thread. It was not the timer base after all. I finally just took the boat the Van's in Gradn Rapids and they diagnosed and fixed it. The flywheel rubber bushing was bad. So every time the boat was started the flywheel was being advanced a small amount by the starter. So at times the timing was correct. At other times it was not. A new flywheel fixed the whole thing. Crazy.

Where is the " flywheel rubber bushing " or did you mean the timing magnets around the hub had slipped ?

 

[cos_man99]

On that particular flywheel there is a press-fit hub in the center. It is held in there by a rubber bushing. So essentially if the crank were an axle and the flywheel were a wheel it would be where the wheel bearing is. That rubber bushing was slipping causing the timing to be off.
