    What is this?

    Can anyone tell me what this hole is for? Oil leaks out and water leaks in. Not good. Is the hole necessary or can I plug it? There are other similar holes but they all have a solid bottom. Could this hole be for some type of freeze plug. I'm at a loss as it is not mentioned in my manual. Any...

    Installing a tell-tale

    I would like to install a tell-tale in my 1974 25 hp Evinrude Sportster. I'm not sure of where the best place is to install it. I have some pics of my cyl. hea and my cyl. block. Where do you think would be the best location to install the elbow fitting?

    compression

    I checked the compression on my 1974 25 hp Evinrude today. Top cylinder was 118lbs and the bottom was 122lbs. I think that is pretty good for an engine that is 35 years old. Does that seem about right to you?
