an "outboard" 4-stroke oil with special detergents that costs 3 x
required???

It also recommends warming up the engine prior to draining the
old oil to assure a quick and through drain.

I assume I can get away with the usual lower unit gearcase oil.

Have new NGK's ordered up on Ebay already.

Inspect Anode.
Check prop nut.

I can't think of anything else other than a few items that
require grease (from the manual)

db~trying not to get too excited.



Is there an oil filter to change?
Yup, the previous owner threw one in with the sale last year.

How about a fuel filter inside the
engine, and on the boat?
At least one inside the engine.

You might want to pull the prop to make sure
200' of fishing line isn't wrapped around the shaft.

Before you warm up that engine on dry land, check the manual. I
don't
know anything about Hondas, but if the flush hose on yours is like
mine,
you do not want to be running the engine with just the flush hose
attached.
Good call, just checked the manual and it does say DO NOT run the
engine
while connected to the flush hose.

If you are using lower unit muffs, keep an eye on them.


Check for places to apply grease under the hood.
Consider installing a proper fuel filter on the transom if you can. If
the filter is out in the open, outside of the bilges, you can install
a glass bottomed unit that will let you see if any water is being
filtered out.
Yeah, and since it's out in the open, you'll have no trouble breaking
the glass and disabling your fuel supply to the motor. Brilliant!


I believe USCG regs do not allow putting that sort of "bowl" gasoline
filter in the bilges.
They don't allow what you suggested.



Minor error...I was thinking plastic bowl but typed glass.


Glass, Plastic. Does not matter. I think neither are allowed for an
inboard with a closed bilge.


A 90 hp Honda is an inboard?

Its a Skiff. i.e. -tub.

Well, considering how expensive new outboards are, I think it is smart
to spend a few bucks on an "extra" external fuel filter, one that will
keep water and crud from even getting to the filter inside the engine.

I think the external filter on mine has a 10-micron screen, but don't
quote me on that.- Hide quoted text -

What about the fact that you may well be voiding your warranty? What
about the fact that today's fuel systems work on precise pressures and
an extra filter may very well change that? What about the fact that
the computer my very well sense a problem with the fuel delivery and
not work correctly?

There are two fuel pumps between the line and the injectors. I doubt
an external filter will have any effect at all.

It HAS to have an effect, it's a restriction.

But is the affect detrimental?

If the external filter handles flows six times greater than my outboard
burns at WOT, what is the net effect of any restriction? And since my
engine manufacturer recommends using an external filter, why would its
use be detrimental in any way?

The external filter keeps water and crap out of the fuel going into the
engine.

That would be on a case by case basis. Hence my point!

Your manufacturer recommends a SPECIFIC external filter. It still has
a negative effect because it's in ADDITION to an already existing
filter.

Isn't that what the internal filter is for?

Actually I do not think inboard enters in to the rules. A closed bilge is
the thing.
