I recently purchased a 1985 Mercury 115hp motor that was attached to a boat that was submerged completely for 2 days in saltwater. The motor itself had the entire lower unit and 4 inches of the powerhead submerged. All of the plugs look perfect except the very bottom one. There is a generous amount of corrosion on some of the lower wiring and on the carburetor. I spole to a local maring engine mechanic and he advised me to do the following:
1. Trim the motor as far horizontal as possible
2. Remove the Plugs and wires
3. Rotate the flywheel and attempt to expel any saltwater in the powerhead (if flywheel locked proceed to step 4)
4. Pickle the block with Marvel Mystery Oil (Pour entire quart into spark plug holes)
5. Let set until finished all boat wiring (wee to month)
6. Remove all corrosion from powerhead wires, carburetor, etc.
7. Rotate flywheel again to expel the Marvel Mystery oil
8. Put plugs and wires back in
9. Attach muffs and wires
10. Crank her up
Can anyone verify this informaton or offer any additional steps that we may have missed. I am planning to do this later tomorrow and would like some additional input. Thanks!
