Oil injection
 

How do you know it's really working? I'd hate to seize an engine. I
remember when they first went to this on jet skis and guys were blocking
them off for pre-mix. Never had an OB with oil injection before.

I considered that but was curious if there is a way of doing it now
since the oil tank is already filled. There is an oil tank in the boat
and one on the inside of the outboards cowling at the top.
All new to me.
Thanks

I carefully marked the tank in 1 pint increments. (do it as you fill
the tank) and checked it against the numbers of 6 gallon cans of gas.
It will actually be a bit less if your motor uses variable feed but it
is a good sanity check. Pretty soon you just get a gut feel for how
much oil you should be using.

is it using oil? Should be.

1. Run engine on pre-mix.
2. Disconnect oil supply hose.
3. Look for oil dripping out.
4. Compare drops/min to manual spec.


What do you mean you don't have a service manual???

Do they put that in the manual? I have it on cd (pdf), but the manual
covers 15 years of motors. And its the mercury manual.

If they didn't they should have. When I had Yamaha's, there was a procedure
outlined in the manual that called for so many drops/min out of the feed
tube
to the engine. This tube was only about 1/8th" i.d. The engine was a 6
cylinder
so it had 6 tubes running from the oil pump. Pretty easy to pull one off
and
watch it drip.

Unfortunately, I gave the manual to the new owner of that boat when I sold
it
so I have no point of reference.

I would think as long as its using *some* oil when running, you should be
ok.
You could add some oil to the gas just to be safe until you verify.
