Seems my marina does not cater to pour your owners....That aside, How do I cope with the pump out technique? Just wanted some quick opinions here.
Can you lug it to the pumpout and get rid of the contents there rather than pouring it out?
It prob'ly makes more sense to carry a 2-3 gallon tank off the boat if possible...'cuz it only weighs about 25 lbs. Swap it out for an "MSD" (designed to be permanently installed and fitted for pumpout) version only if that's the only practical way to empty it.
But a full 5-6 gallon tank weighs about 50 lbs, which is a LOT to carry anywhere and not that easy to control while pouring from it. That makes the MSD version a good choice 'cuz it's a "plug 'n' play" replacement and requires no plumbing except a vent and a pumpout line & deck fitting.
If you really have no way to empty a portable tank, it IS possible to pump one out: stick the pumpout hose into the tank while it's in place via the hole in the bowl. However, I don't recommend it except in an emergency 'cuz it requires bringing the pumpout hose into the boat, and pumpout hoses have a nasty habit of "burping."[/QUOTE]
