I bought a new to me lower unit (lu) and tried to install it yesterday. Got it in multiple times but gears incorrect. Several times forward and reverse seemed to be right but prop would click when in neutral both counter clockwise (cc) and clockwise (cw). Perhaps shifting cable needed adjustment? Perhaps I’m a moron (save judgement, it gets better). Anyways, played with it longer than I’ll admit and went home feeling like a beat horse. Started looking around on YouTube more about situation and ciphering which guys had a clue and who were down at my level so as not to listen too much and I had an epiphany; the lu that was on my boat, just had a male, splined shifting shaft and the one o bought has a male, splined shaft with what looks like a can that a detent pin would ride on as you select gear.
the pic above is the new to me lu.
this was lu that blew pinion gear.
We checked motor serial numbers and they should be the same lu. They also both came from 1986 Mercury 75 hp motors, 4 cylinder, 2 strokes. Housings identical. I may have lost collar from my lu but seriously doubt it. I don’t recall tipping it over or it falling over. I also know when I removed prop shaft from mine to get to pinion gear, the detent pin was loose behind forward gear, not up above.
will this lu work? Do I remove collar from it and continue? Any and all advice welcome. Thanks in advance and off for a beer awaiting words of wisdom!
