After 2.5 weeks of maintenance our C-27, Windrunner. has joined two other C-27's in (instead of at) Duck Creek Marina.
The steepest learning curve was the stuffing box. After three days of sporadic attempts with increasingly larger wrenches, spraying with penetrant, and sincerely using my most inappropriate vocabulary the stuffing box finally came apart. I personally think it was because I had a sawzil in the truck and was prepared to use it.
I am getting a leak into the bilge, and I think the water is (was) coming in through the head intake because: it looks as if the entire intake hose is at or below the water line, the flange at the discharge end of the JAYCO head pump is cracked and there was water collected in the corner behind the head on the midships side.
Do any of your boats have a loop in the head intake that extends above the waterline?
Glad to be on the water...NEXT SAILING!

ALL of my larger boats, both sail and trawler, had vented loops on the intake hoses for heads that extended ABOVE THE WATERLINE. This is good standard practice for plumbing a head on a boat which provides a measure of anti-siphon protection. They are not difficult to install and there are several choices of metal or plastic loops with valves designed specifically for this purpose.

The intake hose on the head in my CP23 does not have a loop, it runs roughly horizontal over to the head. The discharge hose has a vented loop, but not the intake. I don't know what the "correct" way is, just saying the way mine was setup (I think from the factory).
You are supposed to shut all seacocks when not on the boat. A failed hose could sink you. Its best not to open the head intake unless using the head.
My CP23 has the same as Nate, vented loop in the discharge and no loop in the intake.
A vented look (aka vacuum break, aka siphon break) shouldn't be on the intake because the head pump draws a vacuum in the intake to get water into the head. If the head is mounted above waterline, then its better not to have a loop that can't be vented and could cause a siphon. The pump pushes waste from the head through the loop and into the holding tank (or hopefully not overboard). The vent keeps a siphon from forming that might siphon it back into the head.
