Oil injector 2psi check valve correct direction.

[ratchet2]

There is a new replacement check valve on this 86 Mercury 150 xr2, installed by previous owner. Either the Mercury parts book is drawn incorrectly or it’s install on my motor wrong. I just can’t see how the parts book drawing could be correct, with the check valve end going to the small reservoir tank under the cowling?

Never count on a "picture" when direction control is concerned.

Simply blowing through the fitting will tell you which direction to install. In this case, oil should flow into the small tank and be blocked coming out of it

Absolutely, but when Mercury prints hundreds of thousands of manuals & parts books with that “error“, and still do 40 plus years later…. It makes you question what your common sense shouts out load.

According to Mercury the part has been superseded at least four times since the manual was released back in the 1980’s?

Is Merc supposed to recall and reissue all previous versions of the manual each time they change a part supplier or consolidate their parts inventories?

To that end…every manual I’ve ever written or used has disclaimer in the Introduction that outlines the conditions and accuracy of the manual…...

Typical language….
1. Specifications are based on the latest product information at the time of publication.

2. The continuing accuracy of this manual can not be garunteed.

3. All photographs and illustrations used in this manual may not depict actual models or equipment, but are intended as representative views for reference only.

The pic you posted of it on motor, it is installed correctly, and hose needs trimmed shorter.

Thanks, I figured it had to be, if i hadn’t of had a issue with the reservoir not filling completely on the ”maiden voyage”, I would have never second guess it. A lot of talented, well versed mechanics on this site.
