I just bought a small used "pocket" cruising sailboat with what I think is
an 8 hp Honda
outboard on the back. I've never had a boat
with a motor on it before, having sailed only
smaller, non motorized boats, so the outboard is
a new beast for me.
The outboard starts and runs but the previous
owner said he thought it probably had a fouled plug.....so I'm thinking it
could be anything.
As a devout do-it-yourselfer (a.k.a CHEAP),
where should I begin (aside from the Honda Co. and my local small engine
repair shop) to
learn how to tame this critter?
I have a pretty good knowledge of engine mechanics in general and I'm a
pretty handy guy overall.
By the way, The boat is out of the water so I can't just change the plug and
try her out. I'd like to get it into shape by next spring though and have
all winter to fool around with it. Any help, suggestions, manuals,
procedures, tests, etc.
would be appreciated. Thanks

Sounds like she works, so you're at least 95% there. Plugs are easy to pick up.
Probably would be good to get a shop manual to find the right plugs to use,
since you don't know for sure that someone along the way didn't put in any old
plug that fit.

It's about as complicated as your lawn mower; perhaps a slight bit more, so the
manual should be all you really need. If it runs rough and a new (and correct)
plug doesn't do the trick, you might have to adjust the valves or something. Our
7.5 must be 20 years old and I've never done anything beyond replace the
impeller and replace the oils.

If you suspend the motor over a tub of water (I use a trash can), you can run it
a while in your back yard.

They make and you should be able to buy at a local boating store, a
device that slips over the water intake that will let you connect a
garden hose to the outboard for cooling. It looks like a big wishbone
with opposing suction cups. I've used one before and it worked fine.
Don't turn the engine over until there is water in the water pump.
Sometimes when the water pump impeller dries out it will stick and when
the engine turns over you can break pieces off of the impeller.
Fortunately they (usually) aren't too hard to replace and aren't
outrageously expensive.

Jim.

Problem with at least OUR Honda is the pickup is a screened tube under the
cavitation plate. That's why I recommended the tub. If the engine has side
pickups, of course, the "suction cup" thingies work just fine.

Unfortunately the ear-muff type do not fit the Honda 7.5 because of the shape
and location of the water pickup. You can get a hose fitting adapter from a
honda dealer, or run it in a metal wash tub, which is what I do ( I had the wash
tub, and the dealer is 50 miles away).

A barrel will do as well

I had a Honda 7.5 4stroke of '80 as well (sold it this spring, incl.
the original manual) and found that I had to replace plugs every season
and clean them halfway. Else: nice engine!

I have a complete Honda 7.5 HP outboard that I bought to use the powerhead on
my Volvo saildrive system. I am offering the other parts for sale or swap if
you are interested. The Honda outboard was just rebuilt by a factory-authorized
service shop, and is in good condition.

I am interested to buy or swap any Honda 7.5 (or Volvo MB2/50S) parts you may
have and no longer need.

regards,
Jim

Why does the PO think it has a bad plug? Does it run rough? Refuse to
idle? More info would allow us to give more advise. My 8hp came with a
device to clip over the intake but I've tried those before and a garbage can
works better. With a 4 stroke you wont get the large amount of oil build
up. Online contact www.hondamarine.com NO this is not the company web site
that's www.honda-marine.com it's a dealer in Colorado that does mail order.
They'll likely be able to sell you a shop manual and supplies. The west
marines of the world don't support honda and my local shop charges almost $2
for one plastic ring to do the oil change.
