Good move on the fresh water
I've had a couple of motors immersed that have ran fine for years after a good clean up.
Something that many people don't do when repairing immersed outboards is clean all electrical
contacts with a contact cleaner spray (WD 40 works) including the magneto -- this requires you to pull the fly wheel
. Often when this is not done the motor
will run fine for a few months and then develop problems because of corrosion
in areas underneath the fly wheel
. However, if you clean and lubricate all electrical
and mechanical components well then there is no reason this engine won't continue to run for years.
- Clean all electrical connections and magneto surfaces with contact cleaner.
- Remove and clean carb and all fuel
- Remove & clean spark plugs and give the engine a slow easy pull -- this will push any water out of the cylinders. If you got lucky there may not be much. DO NOT try starting or turning over the engine before removing the plugs.
- Squirt some oil
into each cylinder and give the engine a few more slow turns
- Reassemble and fire it up. Only let it run for about 30 minutes then shut it down and let the heat help dry it out more.
You should be good to go after that.
