fixing up an old johnson
How do I work on an old 62 Johnson, out of a body of water? I know that
for my evinrude I've used a huge garbage can, but I was wondering if
there was something like you can use on newer lower units (of IO's, for
example).It looks like the water intake is above the prop, and I don't think the
same thing would work for both. Is there something easy to use? I can make this make more sense if needed. |

: like this: http://marineengineparts.com/shopsite_sc/store/html/page217.htm : barry I'd better clarify.... sorry for another post. The flusher is the metal
plate type flusher TEM380010 (although I'd check the part number to make
sure it's a plate type flusher as I've seen this P/N other places on
the web as a muff-type flusher). the way it's used is it's place *underneath* the cavitation plate. There's
neoprene on the opposite side. The hose tube/fitting tails off the exhaust
snout that is on the bottom of the cavitation plate so the hose
is directed away from the prop. The two metal brackets are secured to
the plate flusher and have carriage bolts on them and wingnuts on the
opposite end. The plate is pressed against the water intake screen
on the bottom of the cavitaion plate and located against the exhaust
snout. The two metal "arms" are swung abound and clamped on the *top*
of the cavitation plate, securing it. barry |

| if you run it in a tank, don't run it too long as the water
will get hot and over heat the engine unless you let a
garden hose run while you are testing it.

| Depends on the shape of the surface around your intakes. On my 96 Johnson,
the whole area's almost flat, just slightly curved, and the rubber muffs
conform pretty well. Are you near a Boat U.S. or West Marine store? As others have said, don't run at high RPMs with muffs. And, even if they
seem to be staying in place while you're doing whatever you're doing, do not
under any circumstances walk away to go get a beer or whatever. I did this
once. As I returned, I saw the muffs slipping off completely. Ran without
water for just a second, so no damage was done. Now, I wipe down the area
with rubbing alcohol to make sure it's tacky-clean, and I *still* don't walk
away from it. |

is the lower unit. I'm a little under the weather right now, so I don't feel up to getting
a picture of what I think is the intake (maybe later today)...but I
think it's the flat section above the prop, perpendicular to the shaft. I could be wrong tho, and probably am. |

| No guts, no glory! Get out there with the camera! But seriously, it looks pretty much like mine. Get the muffs. Keep in mind
that there might be slight gaps - they don't seal like suction cups on a
window. But, if you turn the hose all the way up, there'll be more than
enough water for the intakes to....take in. |

| will those work for the something this old? I thought the water intake
was in a place that the "flushers" would be able to work. |

| I don't think 'muffs' work on my '86 Evinrude Yachtwin 6hp because of
where the water intake is. I bought a good size 'tub' from a local
store and fill it with water. Afterwards, I have to use paper towels to
skim off the oil before I can dump the water. I can see why so many
people are turning to 4 stroke. |

| These 'muffs' are what I use when running my engine while the boat is out of the
water. The water intakes are above the propeller, as you said your's were. I
can't see your engine, so I can't verify they'll work for you. |

| My Johnson dates back to the 1940s, and it still works out of water. Seriously, you need a pair of muffs. That'll keep the engine cool enough
at low RPMs. If you are contemplating running it up to full RPMs, you'll
need a tank of some sort. |
