1981 galaxy 165 L6 chevy motor 165merc outdrive 1978, when prop nut is tightened prop will still move on shaft about 1/4 inch, spacer is in place , is this normal or is this a start of something serious .
When you say spacer are you refering to the thrust washer behind the prop? there should be both the thrust washer and also a washer under the prop nut, sounds like your missing something I don't think that prop should move.
yes the thrust washer and the one behind the prop nut are in place, could this have started when i fist took the prop off and put it back on without the thrust washer and it wore down my prop before i remebered why it was making a weird noise, like metal on metal .
How long did you run it without the thrust washer in it. A 1/4" is a bunch of metal to eat away. When you look behind the thrust washer does it look like there is a worn away area where the prop was pushing against the lower gear box.
ran it about 2 hrs total in 3 tripps to river. its not a stainless steel prop so the gear box should not be damaged should it ? only the prop should be worn down right ? and if so should i replace it and that should solve my problem ? i hope . thanks
