I know it's been mentioned several times before, but I've eleven years of (incomplete) e-mails from the server I don't want to search through. What's the consensus replacement for the M-15's original fixed motor mount? Garelick has several models. On the lighter (engine HP rating) end, the models 71040 (aluminum) and 71037 (SS) have 8-1/2" of vertical travel. Is this sufficient for an M-15? Or would the heavier (7.5 - 20 HP, 11-1/4" vertical travel) model 71057 (aluminum) or model 71056 (SS) be required? There's also the aluminum model 71042 (7.5 - 12 HP) with 14-1/4" vertical travel. Obviously I'd prefer stainless, and Defender has the model 71037 on closeout, but is the travel sufficient? http://search.defender.com/search.aspx?Action=9&Ascending=True&SH=QT1nYXJlbG... And as I am, of course, too large to fit down under the cockpit to get back to the transom (if only I were 17 again!), I've been thinking of adding an access port so I can get to the fasteners. Is a 4" opening sufficient? John Tyner '88 M-15 #412 "Chimpanzee"
