Thanks for the offer, but so far, carting it in five gallon buckets and dumping down the toilet in the garage bathroom is fitting the bill. My hope is that we'll soon be near a marina with a pump-out station. Non-issue at that point.
Just for you, I snapped a few this afternoon. Not pretty to look at, but you get the idea of the layout.
Get some digestor down the toilet if you haven't already and give it a few days to do its work. It ain't pretty, but, once you get on top of it, it'll be so much easier to maintain. That's what I tell myself...
That is in fact your macerator discharge pump; an older TW Vacuflush. The interesting thing is it's connected to the bottom of the holding tank - how the heck would one service it if there was anything in the tank at all? Because, no doubt, service is required when the tank is full; ttmott's law of compounding faults. I'd cap off that bottom port and mount that pump atop / above the tank and drop a siphon tube into the tank for the pump to draw. Marinesan has all of the parts to do that. There are four duckbill check valves in that assembly. There should be a relay that operates that pump of which the ground for the relay coil is switched at the discharge valve so when the valve is closed the pump cannot operate. Also now is the time to replace the vacuum relief valve on the top of the tank to prevent tank collapse and failure.07/16/22 -
Diaphragm pump (not a macerator!)
Both very good ideas; thanks for the suggestions. Unfortunately, space is at a premium, as seen by the attached image of the top of the tank where the vent line exits
The siphon tube goes through a rubber grommet so it can slide in at an angle; it'd be tough to do for sure plus drilling the hole not easy. I would pull the tank out far enough to make the cut and get the tube in. Typically the siphon tube goes towards the boat's aft as that is where the slope goes to. Plus you need to correct that kinked vent hose it will probably break the fitting off. Looks like someone glued the level sensor cap in so that is useless to clean the sensors. So, while drilling the siphon tube hole drill another for a Maretron TLM100 level sensor and abandon that float type. Yur in this deep, why not get it right....Both very good ideas; thanks for the suggestions.

I may be able to find the room for a ball valve, but it's questionable. The siphon tube sounds like the way to go. As for the controls: no switch, no interlock, no nuthin'. The boat is a '92, whereas the pump is a '94, so appears to be added-on at a later date. I would have guessed that the pump would have been powered by the key switch in the head, but no. 'Probably was at some point. At the very least, I'll install a key switch in place of the toggle to avoid inadvertent actuation.
While we're waiting for the blackwater duckbills, I thought it'd be good to get some more time on the outdrive corrosion. By another member's suggestion (I'm sorry; I can't remember who you are!), JB Weld Marine Epoxy was squeegeed into the heavier pits and especially along the trailing edge at the prop. After a day's rest (of the epoxy), it'll be wash, rinse, repeat, but on the other side.
A little painter's tape to act as support while the epoxy hardens.
The trick is to squeegee it thick enough to fill the pits, but thin enough so as to keep the sanding to a minimum. Once that's done, a bit of aluminum-filled body putty follows, then paint. I can hardly wait for the facelift!
I use a non-woven strip disc from HD: https://www.homedepot.com/p/Avanti-...ck-Strip-Disc-PNW040100D01G/202830913#overlay They're pretty aggressive so expect to follow-up with something a bit finer (180 grit?) before painting.
I have some really nice stuff to paint outdrives Jim. I don't remember the name of it, but it's for airplanes. It's a three step process.
Hey! This is my thread! What about me getting first crack at the paint???
That would be me of course. Nice job on the outdrives. I know, its a arduous tasking. its worth in the End! Been gone for a while and just reading some threads catching back up. Nice to see Nater, your carrying us along the journey.
