Drilling and mounting new hull vents for toilet

[Kjetil]

Hello fellow sailors I do not find the porta-potti solution on my Hunter 26 adequate; therefore I am to mount a new proper sanitary systemI am about to drill new holes true the hull of my Hunter 26. Scary… hehe!Does anyone have good advise of hazards, pressure to add when tightening new hull vents (for inlet and outlet)?

What size is your portapotty? What are you planning to do instead?If your only problem is holding capacity, there may be a much simpler--and a LOT less expensive--solution than replacing the whole system with what you call a "proper" system....'cuz a "proper" system requires a lot of maintenance.
