Evinrude 70 two cycle, 2 questions
 

Greetings all,

Question 1,

I am running Amsoil Sabre 100 Outboard at the 80:1 ratio. Do you feel
this is any real advantage over the OMC 50:1 factory oil? I would consider
longer engine life an advantage if it is a reality. Cleaner running, with
less fouling if that is true. Anyone see any real differance?

Question 2,
Whenever I am finished boating for the day, I always remove the fuel line
from the engine and idle the engine until it dies. This is mainly to prevent
raw fuel from slopping around when I trailer the boat home with the engine
tilted fully up. Am I harming the engine do to one or two cylinders running
out of fuel/oil mix prior to the engine coming to a complete stop?

Thanks guys.

80:1? That's way lean for an engine of that age and hp.

Or at least I would think so.

There are two schools of thought on this. I'm in the just shut it off
camp. Others believe differently.

I don't believe that there is any definitive evidence for one way or
the other.

As Shortwave said - 80:1 is too lean. Just run the standard OMC or Merc oil
at 50:1.

I would never consider running any engine without oil for the crank and
bearings and cylinder walls. Running the engine out of gas does just that
since there is no more oil/fuel mixture in the crank area.

If you use good gas and oil ( I personnally use only 92/93 octane fuel as it
tends to not varnish as quick and I have never had an engine go down or a
carb rebuild on any of my boats) then you should not have a problem w/ it
setting for a month or so.
I also fill up on the way to the lake to make sure the fuel is fresh instead
of filling on the way home so all the gas is old if it does set for a month
or two.
I also insert fuel stabilizer over the winter.

Use TCW-3 oil at 50:1 or richer (we do not have a marina, so all gas is
carried in, we mix a pint to the 5+ gallon can for about a 42:1 ratio)
and save your money and your engine. OMC/Bombardier & Mercury oil is
now sold at WalMart. Run a little rich and save your $$$ engine (have
you priced a new one?!).

That's a tough question due to the trailering issue... before the engine
just starts to starve out, hit the choke (if it has an actual choke -
not the enrichment circuit) and shut off the engine if you are concerned
about fuel handling. Disconnect at the tank, too, to relieve the
pressure from the fuel line.
