Can anyone tell me the difference in a the following Evinrude/Johnson CD/4 powerpacks? I bought a Johnson 140 Looper for spair parts (can't tell the year, tag is dammaged but is supposed to be an '85-86 and the dealer said they were interchangable(?). Most of the parts are the same p/n as my 85 120 looper except the powerpack. Below is listed the particulars. I'm just wondering if they are interchangable?<br /><br />From the 120: Markings =:<br />CD 4/8-61L<br />PN 852645<br />17 DW-0A<br /><br />From the 140: Markings =:<br />BRP<br />CD4/8-67L<br />583101<br />13 D1B-BA <br /><br />Thanks,<br />TN Fisher
