Default 2 stroke / 4 stroke advice

4 strokes are great for a lot of reasons, but if fuel quality is
questionable, they can be more trouble than 2 strokes. I've had fuel
problems with a 9.9 Yamaha 4 stroke, and an ob mechanic said water or
trash caused more problems w/4 strokes because of the smaller jets.



Also, if you look back at the "good ol' days", remember when
"winterizing" the old 2-stroker meant hauling it up the dock and putting
it in the garage until spring? When you took it out in spring, just as
greasy as you put it away, it wasn't all rusted up coated with oil like
it always was. You poured PREMIX gas into it and drove away.

We have a Nissan 8hp 4-stroker for a Foldabote 12 on Lionheart. The carb
has been apart a few times, now, because it had raw gas in it that
evaporated into solid shellac, plugging the jets so it wouldn't start.
This wasn't an issue with the old PREMIX 2-stroker because the oil in the
gas DIDN'T evaporate and kept the stuff left in the carbs in LIQUID form
the new gas would simply remix with and away we went. My little Yamaha 3
with the gas tank on top is like that, too. It was stored for years and
the premix still kept it from solidifying to shellac.

Changing the oil on a marina dock or sailboat STILL sucks, too....

As to the 100:1 oilers...no thanks. 50:1 is too thin to oil crankcase
bearings, no matter now much greenies and the EPA hype it. When I sold
my 1997 Mercury Sport Jet 175hp-powered Sea Rayder, all 6 cylinders were
within 5 pounds of their original compression and ran great on 40:1
PREMIX, the troublesome Mercury plastic oil injection pump and system
having been removed as soon as I found out about the 2nd recall blowing
powerheads with NO LUBRICATION. That boat's still running and the engine
had well over 1000 hours on it....on PREMIX.

According to EPA, all lakes that have had 2-stroke engines running in
them for the last 100 years must be 6" deep in motor oil. See it?
Oil floats, ya know!
