I got this motor from a junkyard last year. Got it running well and mounted it on my 17' Boston Whaler. I thought it was strange that it only had two holes for mounting bolts. After finding a parts manual, I see why. There's a couple brackets I don't have that are included in what the parts manual calls a transom mount kit. My local dealer says these parts are no longer available. Anyone have an idea where they can be gotten -- or whether they're even necessary?
