Hi People, <br /><br />The coil on my Johnson 100ESL72 is looking abit sad, it was cracked and covered with Silicon.<br /><br />Anyway, I have an Evinrude 85HP, according to my parts list.. The two coils have the same part number 580740.. but one is black (the newer Johnson) and the other is grey (The evinrude)<br /><br />are they compatable black and grey? <br /><br />whats the difference? I assumed that if they had the same part number they'd be the same.. but that doesn't appear to be the case...<br /><br />The Grey one from the evinrude looks like an aftermarket replacement.. it has:<br />[To Fit OMC 580 740] <br /><br />And its made by a company called:<br />Prufrex (made in Germany)<br />written on it.. so its probably a non genuine replacement.. so would you guys suggest that I use it instead of the cracked genuine one? (which seems to be working ok, but who knows if its 100% and not leaking abit.. though I can't see any sparks around it at night.)<br /><br />Any thoughs people?<br /><br />rgds<br /><br />Frank
