I bought a Honda 4 stroke 2hp motor 6 years ago. The first required
maintenance is at 10 hours; changing the engine oil and the gear case oil.
I used it for about 2 hours and then put it in storage because I sold the
boat I used it on.
I drained the gas, changed the engine oil and the gear case oil.
This year I bought a new boat and put another 2 hours on it, and am putting
it away for the winter.
Should I bother changing the oils? It isn't called for even once for
another 6 hours, and I have already done it once.
On the other hand, I don't want to wreck an expensive motor for a little
What's the regular gearcase and engine oils schedule after the initial
changes? I'm sure it's much longer than 10 hours for the breakin oils.
I would go through the normal storage checks and not worry about the oils.
Bingo. That got it. I would certainly recommend changing the oil and
anything that might have been contaminated by water, at the end of every
season. The exception would be if you did not use it at all and it never
was in the water.
Interesting that everyone says to fog the engine on the boat motor, but no
one would suggest it for a lawmower engine. Is that because it is used on
the water, so there could be contamination?
I have a can of fogger, so I will do that; but wonder what the distinction
We change our boat oil in the spring. I have found that the metal
filings tend to accumulate during the winter and the oil (looks like)
it is absorbing moisture. The oil tends to be more watery in spring
than when we parked the boat.
Even if you only used it twice... I guess it depends on where you
store the boat. Ours is in the driveway and I suspect all that snow
and rain is making its way inside. :(

I fog my lawnmower and snowblower. If I was going to park my car for 6 months,
I'd fog that too. It's so easy to do, you'd be hard pressed to find a reason NOT
to do it. When I fog my yard machines, I also shoot fog into the crankcase via
the oil fill to hopefully protect the crank and rod bearings a little as well.
I've seen what amounts to fogging suggested lots of times, including
in owner's manuals for lawn mowers and other engines of various
types. Most times they say to squirt an ounce of oil into the
cylinder, then crank the engine a few times without starting to
distribute it around. It helps prevent any rusting. However, in
practice, I guess the question is how much diff does it really make?
I doubt anyone has done any testing to verify it.
In a marine environment, the air tends to be more humid, so it's
likely more of an issue there than for your lawnmower that gets put
away in Nov. I always fogged the boat engines, but never any other.
