Default Spring servicing Honda 90HP 4 stroke

I want to change the engine oil. The manual calls for SAE 10w30...
Ummm...This seems to easy and straight forward... Isn't there
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? How about a fuel filter inside the
engine, and on the boat? 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. If you are using lower unit muffs, keep an eye on them.

Check for places to apply grease under the hood.
