1991 Mariner Lower Unit RH 20"
Factory lower unit from 1991 Mariner 175. Everything works well. Removed because of low compression on powerhead.
RH rotation
20" shaft
1.87 ratio
$400 plus shippingLast edited by hayajustin; 10-18-2021 at 01:21 PM.

Yes, pictures would help. There are some minor chips on the leading edge, but not terrible. Then, there is the mariner paint fade/erosion. I can remove from the midsection for better pics if needed.
