All - I just wanted to update this thread with a post I made over on anything-sailing to let everyone know the project is complete and recommend an inexpensive tool that made installing the odorsafe hose a piece of cake.
At long last, we finally have a checkmark in the project complete column. This weekend we finished attaching the final hoses for the new head. The only original parts left in the system are the thru-hull for the overboard discharge and the deck pump-out fitting. We were going to replace the deck fitting, but the original from the factory is held in place with epoxy, so we decided it wasn't worth the effort to grind it out. We installed a Raritan PHII Compact throne, all new SealLand OderSafe hose (both waste and vent), new holding tank and TWO new vents. The water intake for the head is plumbed into the sink drain so we can easily use fresh water to flush. We decided to bypass the overboard pump-out as it is highly unlikely we will ever have this boat in a place where we can use it (our sailing grounds are all NDZ), but I did install a diverter valve so that if plans change or a subsequent owner wants to add that capability it will only require adding a couple hoses. We unfortunately had to use a bladder holding per the original design, as there was no feasible option for installing a rigid tank without MAJOR modifications, but I'm confident it will serve our purposes for the next few years. While this upgrade won't make the boat move any faster, it will certainly come in handy when the crew has to make a fast movement. Thanks for all the input and suggestions from members here and on AS while we worked through this process.
For anyone who has worked with OdorSafe hose, you know that it is very difficult to bend around curves and to get onto the fittings. We found that it is best to do the work on a warm day, and to allow the hose to sit in the sun for a bit before trying to install. We also changed some hose runs to avoid tight curves. We found that installing the hose on the fittings was VERY easy with the assistance of a $10 tool. Specifically, we purchased a small tailpipe expander at the auto store. Prior to installing the hose on a fitting, I would stretch out the end of the hose slightly with the fitting. Installing on the fittings couldn't have been easier, and we didn't need to use any lubricants or boiling water as has been mentioned in other places on the web. Before we did the first fitting, I made sure that the hose would eventually shrink back to its original size so we wouldn't have any surprise leaks. Turns out that about five minutes after putting the hose on the fitting it is next to impossible to remove it, even before putting on the hose clamps. If anyone has plans to work with this type of hose, I highly recommend that you get yourself a cheap tailpipe expander like this:
