Re: omc or mercury
I don't know, this is like the question:
"Chevy or Ford" they both are just fine as long as you do you part, I have owned Evinrude, Johnson, Mercury, Elgin and all of them were just fine as long as I maintained them, just as my Chevy's, Dodges, Fords and Plymouth's..
The key is YOU, keep them up to snuff, maintain them as your suppose to and you should have no problems.
Yes, I am aware there are bad products out there, but 99% of the time, it is the owner that does not do his/her part to ensure as few problems as possible.
