So today I drained and refilled my lower unit while waiting for parts for another project. Noticed some amounts of metal shavings, not major like shards just more like tiny flakes and only a few. I then tested to see if my clutch was fully engaging. I put the motor in forward full throttle and when i turn the prop with my hand instead of turning the crank in the engine the prop feel as though the clutch is popping in and out of gear. When I go into reverse and turn I am able to turn spin the crank shaft in the engine just fine. This boat has very Low hours on it I can confirm. gear oil was not milky from last time I replaced it. Boat sat for many years unused. Shifter on engine out of alignment maybe and if so how to adjust?? thanks everyone on hear
