As it turned out, the manuals were pretty much useless - just general stuff about the overall boat
- nothing really specific about any of the equipment
onboard. I guess that is probably because each boat could be fitted with different equipment
, so I have individual manuals for motors, electronics
etc. but these would probably not be relevant to your particular boat.
On ours, we only have one "head related" switch on the panel and that is for discharge. We don't seem to have a fitting to discharge to a pump
out station that I can see, so we just head
out to sea to discharge - not that we use the toilet that often.
Sorry I can't be of more help mate, and good luck with it. I would suggest if you get in touch with a local shipwright / vessel management company they will be able to give you the lowdown on how it would work
