    Have a 1955 Evinrude 15 HP that I am putting back together, and I noticed on one of the lower unit gears that the brass bushing bearing just slips in and out. I checked another one and it seems like it’s a press fit to keep the hole orientated towards the hole in the gear.
    Do you think the one pictured is going to be a problem?
    Thanks,

    No problem here….Keep in mind that the bronze bushing is grooved so oil will flow to the oil hole at all times, regardless of whether or not the two holes are lined up..

    The reverse gear has a free-floating bearing because the gear turns in opposite direction from the shaft (in forward gear/high speed). The forward gear is not free-floating for the same reason, plus it is a thrust bearing transmitting horsepower to the boat.
