Outboard that won't restart when wet(?)
I have a Johnson 25 hours, that runs like a scalded dog... However, once you
run it for a little while, and then shut down, it will NOT restart. If I take
the boat back home, and let it sit for a couple days, then go back out - same
thing. Starts after 4 or 5 pulls, runs fine... then after you shut down it will
not restart.I believe I may be getting water in the engine somehow, but I'm not really a
mechanic. Anyone out there have an idea what to check? Sincerely,
"Tired of rowing" |

| When you go to restart it, choking would be different for a cold engine vs.
a warm engine. I don't see how water could be getting in and not causing
you problems while it is running. Do you smell fuel when trying to restart it?
Have you taken the spark plugs out to see if they looked fouled?
Have you tried letting the engine cool down for an hour and then try
starting it?
How about repumping the squeeze ball to make sure you have adequate fuel
pressure when restarting? Jeff |

| I am no mechanic, but it seems I have read about this kind of problem being
caused by the rings sticking when the engine gets hot - as long as it is
running it is fine, but won't get enough compression to start once stopped.
After cooling off the rings spring out again and you get enough compression.

| You're pull starting it, so I suspect it's a tiller steer motor. Same setup
as my 20. I had a very similar problem, but it was intermittent. Motor
would almost always start one or two pulls first thing in the morning, then
it would intermittently either fail to start or be very balky starting for
the rest of the day. When it started, it ran great. But sometimes, getting
it started (after the initial run in the AM) was an ordeal. Problem turned out to be the 'kill switch' on the tiller. (the little red
button you push to shut the motor off, even if you're not using it as a
kill switch). Only takes a few seconds to troubleshoot. There's a rubber
covered inline plug connector on the starboard side of the powerhead. It's
mounted in a little spring wire deal that prevents it from coming apart or
moving around. Next time the motor won't start, take it out of that little
wire clamp deal and unplug it, then try it. If it starts right up, you need
a new kill switch. RichZ©

| Is the water pump working properly. Could it be getting hot from
insufficient cooling? Sarge |

| Dear "Tired of Rowing", If I were you, I'd get the motor checked out ASAP! It sounds to me like the
motor is getting hot, the pistons and/or rings are expanding and sticking in
the cylinders. Is there a solid stream of water coming out of the motor?
Evinrude/Johnson motors are notorious for getting blockage in the water pump
outlet. Also, have you ever had the impeller changed in the water pump?
This should be done at least every couple of years, regardless of how much
the motor is run. The fins on the impeller will take a set and the pump
loses efficiency. Depending on the age of the motor, it could be in the control module too,
that when heat builds up in the powerhead, something isn't liking it and not
functioning properly until it cools down. But either way, if you run the motor too long with this condition, you'll
have to change your name to "Forced to Row." |
