I have a mid-60s Evinrude 60 hp motor that I just got on an old boat and there is a hole in the lower unit that does not look like a factory drilling. It was suggested to me that it may be milled. Does anyone have a mid-60s Evinrude that they can go do a visual on for me? It is the hole right above the phillips head screw near the oil fill plug on the port side of the lower unit. Is there a diagram anywhere of the various water weep holes?

Not sure…this diagram does not really show. Search for other years?

Darn it, I’m the guy that told you that is a milled drain hole. To prove it, I just went out and took a picture of one. Now my computer is acting up. Gr.r.r.r. When I get it, I’ll post it.

Definitely a ding. It could let water into the gearcase if it opens to the section where the shift rod is.

Im not sure why they are there, but every V-4 of the era has one that I worked on. I’m with Frank on this one. It is a machined mark for some reason. The oring you see in the parts break down seals the complete area and that little notch is outside of the oring.

I gave away the upper section of this gearcase, but you can see where it was on the lower section. It is a milled drainage slot to keep water from freezing and busting the upper gearcase section.

Frank… I owe you a beer. Yes I did post this question on another forum and you can see why I had my concerns. That hole does NOT look original but your picture verified it for me. Thank you for taking the time to post that pic. I looked at lower unit pics on Ebay and google images and could not get a clear shot. Thanks!!

Nice feature. Making sure that hole is clear should be part of the winter storage procedure.
