1985 115hp Merc Outboard Oil Pump
 

Hello All,

I recently got my boat out of storage and while looking it over noticed
a very small oil leak in the rubber hose between the integral oil tank
and the oil pump. I have since replaced the line but can't figure out
how to bleed the system of any air. I have the Clymer Shop Manual and
it shows the bleed screw for every other model but not this one. (my
luck)

To help, I have uploaded 2 images that may be of assistance. .

1. The drawing of the pump in the manual:

2. A actual picture of my engine showing the pump:

Worst case, I suspect I can run the engine from a pre mix external tank
until I am sure oil is getting injected into the system. But I sure
would like to know which is the actual bleed screw.


Any help is certainly appreciated.

Regards

Marty
