I dont mind If you need the measurements. Sorry ive never measured them before. Did you pull something other than a omc off the boat? I know Mercs are different but the v4- v6 omcs are the same.
I was just measuring the mounting plate on this Detwiler jackplate and I think they're different then the holes in my transom.<br /><br />c/6<br /><br />Hooty
It should be the same pattern. Everybody has used the ABYC standard for a very long time now for most mid size engines and higher.<br /><br />Good luck!
