All this to change the spark plugs? Crap! I'd hate to be out at sea and
have some need to change them!


On a 4 stroke, with unleaded gas, I am not sure why you would have to change
them. My plugs were replaced at 400 hours and they looked virtually new.
Plugs in cars these days will go 100,000 miles.

Many thanks to Brian, dp, Greg and Joe Blizzard. The spark plugs will
remain in place unless there is a definite need. But, then again without
being redundant, I wonder why they recommend removing the plugs and squirt
oil before storing for the winter. Your thoughts on this gentlemen.

Certainly you'll need to get them out to put oil in the bores so as to
stop rust over winter.

Make sure you turn it over a few times by hand with the oil in & the
plugs out, also next season give it a quick turnover, again with the
plugs out, to make sure you won't create an hydraulic lock when starting
for the first time.

When you put them back in each time (just finger tight for winter) make
sure you use a dab of neverseize or similar, also any other bolts,
you'll regularly need to remove. It makes the job easier & stops
corrosion within the threads.

Ah I keep forgetting you guys have winter. Do you do the same for your garden
equipment?
I don't suppose cranking it over with fogging oil would do the trick? (safety
lanyard out so it won't try to start)

Ah-ha. 4 stroke. I'm used to these older 2 stroke jobbies that seem to
foul plugs all the time. Honeslty I've never changed one while at sea, I
hope I don't ever have to. Just seems like it's one of those "extras" like
a spare prop or something you might like to have with you. That, or your
sea-tow membership.
