I know many of you have adjustable motor mounts for your M-15s and M-17s, and I'm looking (again, I've given up in confusion before) at the various offerings at Defender and West Marine. Obviously, I'd prefer stainless steel to aluminum, everything else equal (but nothing ever is), but what's really confusing me is the drastic price difference ($150 - $200) between those identified as for two-stroke and four-stroke engines, though I assume this is a max weight issue. So, my question(s): 1) Does any of this 2-stroke vs. 4-stroke matter for the 2HP, 4-stroke, 29-lb (something like that) Honda I use? 2) Vertical travel; what's right for an M-15? Suggestions always welcome. What's your preference among those here: http://search.defender.com/?Action=2&AnswerId=61276&SH=QT1nYXJlbGlja35CPWdhc... Thanks, John Tyner M-15 #412
