I'm starting to shop for a motor for my boat and I wonder if there is a standard hole pattern for mounting the motor to the transom of a boat ? My boat had a 1994-150hp Mercury on it before I got it. Thanks for any info you can pass on to me.

Digger 9,<br /><br />They're all the same with motors the same year or newer than your '94' 150. <br /><br />I'm not sure when they were standardized, but it was quite a while ago.

Re: Motor mounting question

The bigger motors follow the BIA standard, I believe early to mid 70s was the starting point, but I could be wrong.

Re: Motor mounting question

The bolt pattern for mounting outboard motors was designed by Johnson and Evinrude for the 1960 75hp V-4 and has been in use ever since. Other manufacturers adopted it in later years. Just a bit of trivia for y'all.

I recently bought a 2003 Key West Center Console and installed my 1985 XP 150 Evinrude without a problem. :cool:
