How often should an old (1954) outboard motor be flushed out when used in saltwater instead of fresh water.?

Answer 1

Every time you use any outboard in salt water it should be flushed with fresh water....no matter how old or new it is. If you don't flush it out as soon as you pull it out of salt water the salt dries up and hardens in your cooling system. This restricts the cooling effect of the water flowing through your engine and causes your engine to overheat and damages the pistons and cylinder walls. Eventually you will be looking at rebuilding or replacing your engine!!!!

Answer 2

Just as often as a brand new one. Every time it is used. Salt is very corrosive and eats the internal engine parts. Even worse when you take it out of the water, because the water goes away and leaves salt deposits.

Answer 3

gas stabilizer is a solid theory, basically make certain you run it throughout the the carbs in any different case it does little solid in conserving your engine working easily. i used a 13 gal. kitchen trash can crammed with water to run my little 6hp motor in... i decrease a hollow interior the backside side of the trash can and plugged it with a boat plug ( for draining after use ). you may desire to run the engine at multiple rpms... ( it is not specific ) to work together all working components. i could try this a minimum of each and every 30 days and it does harm, in case you think of roughly it, to furnish the bulb a pair of solid squeezes as quickly as a week or in an attempt to maintain sparkling gas shifting.

Answer 4

After EVERY use, don't use those "Barrels" filled with water on the dock to flush with, everybody uses that, so it's "Salt water" use the "Rabbit ears" to flush with the garden hose.

Answer 5

I use my 76 Johnson only in saltwater and flush it after every use.

Answer 6

every time especially on the older motors as the paint and primer technology was not as it is today. also the aluminum surface prep(most important part) was not as today.also sacrificial anodes(corrosion control) were not used. older motors also have dings and bad spots in the paint and finnish that will accelerate corrosion. its important to repair this. good boating!

Answer 7

if you are done with it for awhile my manual for my 35 horse says for storage, rinse, the only real precaution mentioned is not to leave it hanging in the salt water when not in use, the parts are treated for saltwater operation, but re- wax the outside painted parts more often

Answer 8

It's a antique every time an stored indoors

Answer 9

after every use.
