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.

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.
