The casting indicates a Chevy 305 96-98. Is there anything else on the Engine I can use to narrow it down to what Merc Service...

    OMC Stringer Anode

    I saw this picture below on Ebay. It is pretty close in age to mine, 1976. In part of the description the seller says this: "The only thing it could use is a new anode/exhaust piece. This one is sacrificed about 50%." This will be the first time I have heard this part described as an Anode...

    OMC - What does this mean to me

    Below is a picture of a Water Jacket Cover Plate. I kinda know what it is. I kinda know what flows behind it. What I wanta know is: 1) Does it need maintenance? or is it a "Not broke, don't fix it" kind of thing. 2) Does it have any diagnostics value? If it does then how would I use it to Fix a...

Is there someone in this group that has an Outboard on their boat as a backup to their IO? I have pasted below the original...

    OMC Stringer Why is it a Plastic Plug?

    I have been trying to figure this out for awhile and was waiting to verify what it was for. No hurry, the plug was melted any way. Everything on this Outdrive is either metal or rubber.

    OMC 75 Upper Ball Gear Assembly

    The above photo is a drawing of a Ball Gear Assembly from a 75 OMC 225HP. The Bearing Retainer has marked on the outside 21/17. I suspect that is a gear ratio. That gear ratio did not start showing up until 1982 or so. I believe the gear ratio for this drive is typically 21/16. It appears that...
