I have a 115 evinrude. I hit a rock & broke a hole in the gear case. I have another solid case that has some shifting problems. I'd like to switch gears from one to the other. <br /><br />Can this be done without the special tools in the manual? They show a pair of truarc pliers and a special puller. <br /><br />Thanks in advance,<br /><br />Greg Hodges
