Identification and Purpose of part.

[turtle1173]

I have been curious about the purpose of a part on my outboard.<br /><br /> It is a screw on top of the head. This is a 1976 55HP Chrysler. I don't know if it is a drain of some sort or what. My manual has a picture of it but no description or identification. I wouldn't think it was a drain because it is on the top but who knows? It is just on the transom side from the thermostat.<br /><br />Thanks for the info.<br /><br />Shane

Does this screw look like a pipe plug?<br /><br />c/6<br /><br />Hooty

Yes, I would say that's a good description of it. It is not like a regular screw but has thick threads.<br /><br />Shane

Probably a plug that taps into water jacket for temp probe or water pressure guage.I think that's where Hooty was going.
