I beleive this means I have a leak in some seal for the lower unit. When I changed the gear lube last night there was a ribbon of brown in the old black oil.
Wondering how hard it is to work on the lower unit?
Is it usually a seal that goes bad or can it be worse and what to look for?
Also if it is just seals wondering how hard of a project this is and if I am taking it apart for this should I also be doing anything else, ie water pump, impeller?
I also noticed there are no washers or o rings on either the drain or vent plug, should there be?
