The clearance on a G2 when totally tilted up is like 29", maybe 28", from the mounting bracket of the engine to the wall of the transom, I'm not positive let me look. I'llsee if I can find the document from Evinrude.
OK I'm back, check out this post. Because the eTec tilts at 80 degrees you have to be careful for clearance. Looks to be right at 26". You should be good.
