What size/type of screw is this?

[Scholarship]

I had one of the screws identified below work its way out this weekend and I can't find it anywhere. I made the mistake of not taking one out that was left to bring home and use to make sure I bought the right replacement. Can anyone tell me what size screw I need here? I think its hex head machine screw.

Don't yell at me if I'm wrong... might be metric also... I did use a 7/16 wrench to remove mine.

I would take one from the other motor and bring it with you just to be sure...

BTW, that bilge is WAY TOO CLEAN! :lol:

its probably around ON top of the engin somewhere.. get a magnetic probe and probe around a little. you might catch it and pull it up from where ever it fell from..

I’m amazed you forgot the other screw when you ran back to the boat with a camera and that big red arrow to point to the hole. Why did you not get the other screw then?

Kidding of course.
