Hello all, new here so hope this is going in the right spot.
I have a 1987 Carver Aft Cabin
with original twin I/B Merc 340hp, mated to velvet drive 10-18-010 with 2.57 reduction gears on the tail end.
My question is regarding the reduction gear
output seal. Built the metal bar and broke the nut loose, however mine has a castle style nut on it instead of the nylock. Does this nut still have to be replaced?
200ft lbs is the correct torque for this nut?
