Thanks Gary,
Do you think that is the original designed location for the tank? Is your layout with the dinnette on the starboard side and a settee on the port?
I'm trying to establish where the original equipment was and try to replace the original sized tank. Are the thru hulls right there?
Thanks again for your information.
Cheers,
Ron
you have the aft galley, dinette interior......all three interiors produced for this boat.... aft galley dinette, forward galley dinette, and traditional have the same head compartment. On the dinette models the holding tank and through hulls are in a compartment under the forward dinette seat, adjacent to the head, separted by the main bulkhead... There are probably holes for plumbing in the lower glassed part of the bulkhead. There will be a hatch under the cushion to access the holding tank, y-valve, and through hull valves.
A 5 or 6 gallon rectangular plastic tank will fit in the compartment..you may have to construct a simple plywood cradle to accommodate the tank. On my boat there are two plywood pieces cut with small insets for the tank, then shaped on the hull side to allow them to be wedged into place.... The tank sits as high and as far back as possible in the compartment. This gives plenty of room for the plumbing.... and access to the through hull valves.
I may have a few pictures..... I'll try to find them and send them to you via a private message.
If you look at the old parts catalogue shown on the
owner's website you'll see a 21 gallons msd system KIT that was offered by Catalina Yachts.... This configuration shows the holding tank located under the vee berth.... mine is nowhere like that.... the system shows the head discharging directly to the tank.... the discharge side of the tank shows a tee fitting with hose going to deck pumpout fitting, or macerator pump to through hull for direct out. The glaring problem is the use of "GATE" valves..... Not Good...... only bronze or resin ball valve should be used. ........ anyhow.... I suggest you call CatalinaYachts customer service and see what they have available....they can probably recommend a better system.
