I purchased a 15hp johnson electric start from a neighbor that occasionally popped out of gear I disassembled the lower unit and replaced the thrust bearing and washers item #s 0336296 and 0388000 (everything else was in good condition)and reassembled the gearcase with the carrier tightened up against the housing there was more endplay than I was comfortable with but being as that was the way it was I put it in service and have about 10hrs on it Yesterday I heard loud clunk like I hit something. the motor continued to work fine. I am wondering (and concerned) if the endplay could be the cause. The question is can I add a shim the correct this and if so how do I do it Thanks
