[QUOTE="bassboy1, post: 286714, member: 55"] On anything halfway modern (and by that, I'm talking mid 80s on), the bolt pattern IS standard on anything larger than the 'portable' size engines. In some cases, that pattern goes back to the early '60s, as BIA adopted the pattern that OMC started using way back when. In your case, it is very obvious that the holes are of the BIA standard. If you are going with a 40hp Mercury 4 stroke, it will have the correct mounting pattern, as a 4 stroke implies it is fairly new. Almost any commercially available jackplate should be a direct bolt and go, as well. [/QUOTE]
