Re: Close to statistical study on OMC RDS Gear Cases

quote Chris_P:

They are very often restricted and plugged. I have to drill many of them out to clear the path. Even had to remove owner installed plugging devices! Guys don’t like seeing their gearcases draining nasty sludge, but that is very normal, and protects them from the damage you describe.

Since the crankcase drain recovery system was installed on my 57 35hp the bottom drain drains so clear that I think it has become plugged and is not draining.

So every once in a while I take a piece of thick weed eater string and push it up the hole using vice grips. It helps to pre bend the tip of the line some. I push about ten inches of line up inside from the bottom. When I first got this motor about 3 years ago it was plugged so hard it took a small diameter metal rod with it’s end shaped like a flat blade screwdriver to open it up.

Everyone ought to know about these drain holes but many do not.
