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???
