i'm helping a new owner with a 1990 built, viking 63MY and i have a few questions that are left unanswered by the "light" owners manual...
unfortunately there are no blue prints or serious diagrams (wiring, plumbing, etc...). he's going to check with Viking but in the meantime, knowing how good YF
is, i'm sure someone may have the answer!
1)- the boat has a 1000USG primary fuel tank under the master, as well as an optional fuel tank under the forward SR. there is no mention or info on the optional fuel tank. previous owner/broker mentioned 400USG, but i'd like to verify that nr.
2)- according to the manual, the water tank is under the forward SR... this one, because of the of the aux fuel tank has the water tank under the master bed. any idea of the capacity?
3)- same question with the hodling tank, it's not in the ER as per the plan but next to the aux. fuel tank forward... capacity unknown...
4)- any idea where the holding tank vent may be? i've opened every hatch, and panel i can find and no luck.. i want to know if it has a filter.
