Hi Seniorquill, I know this is an old thread but a quick question. Did you replace your alternator for an externally regulated one as part of this install?

I've got no experience of wifi wind instruments, but I do have a wifi connection to my Quantum radar. It works just fine - except when the boom is dead central.

Navionics runs just fine on my latest gen Axiom Pro.

Thank you Ed. I'll look for that here in the UK. I'm also seriously considering blanking off the whole thing. 🤔

I'd love to know what the internal diameter of that hose was.

Hi Jim,

Definitely coming from aft, somewhere near the transom. It could be the lockers but my money is on the scuppers.

Here ya go. I don't have a photo of the cockpit floor, not something I bother imaging. But this shows the two scupper drain holes in the transom. The drains in the cockpit are in the far aft corners in the gap between the aft lockers and the side benches. I know LA Lady isn't the only MkII to have them!

I guess they're there because of the option to fill the gap in the transom with a solid walled seat. I have it but never use it.

Keel,
What makes you think you need to replace your scupper hoses?  Mark II C34s don't have scupper hoses.

Mine has scupper hoses! This oddity has been discussed on other forums.

I think they're the source of water in the bilge. Probably rainwater and washdown water seeping through small cracks. I've not actually seen this happen but I have seen water running down from the stern towards the engine bay when the missus is up tops cleaning. Pretty certain its not caused by leaky cockpit lockers. Furthermore, after taping over the scuppers the bilge is now much drier.

The hoses are OEM so now nearly 18 years old. Definitely time to replace them. The problem is, they're probably sized to US measures not metric. Thus very difficult/impossible for me to get here in the UK.

Mine does!

Hi All,

Resurrecting this thread because I suspect the scupper hoses on my Mk2 need replacing. Can anyone tell me what diameter and type of hose I need for this? I can't find replacement items on CD's website.

Pretty interesting measuring the difference between the old Sherwood pump and the new JMP one. The old pump was 5mm short of fully engaging in the camshaft slot. The new JMP is only 1mm short (which is probably about right). This is all accounted for by the fact that the key on the new JMP pump is longer than the key on the old Sherwood.

Maybe the Sherwood was the wrong one?

Hi Raymond,

Welcome to the club! I was in your position 2 years ago and opted to splash some cash on a Raymarine system comprising Axiom chart plotter, i70 multifuction display, new Raymarine tri-sensor (speed, depth and water temp), a new Raymarine anemometer an AIS700 and a Quantum radar. I decided to keep the old Raymarine wheel pilot and it's head unit. Big mistake.

The advantage of buying a whole new set was that it was child's play to set up. Literally plug and play, though you do have to do a bit of boat yoga to run the cables.

I can have the chartplotter repeated on iPad but it's pretty clunky. Instead I run Navionics independently on the iPad and iPhone which gives me additional displays,  while ensuring system redundancy.

A NEW Raymarine wheel pilot is an OK autopilot system, provided you use it for what it's designed for - light coastal work. It is not up to the job of sailing downwind in large swells. Ours broke 150 miles offshore leaving us to hand steer for two days. No fun at all. An old system is a breakdown waiting to happen. I wouldn't like to rely on even a new one when singlehanding during a gale.

One good reason for linking the A/P to the rest of the gear would be to let it steer by wind angle. But in two years I've never bothered.

If you need to save money go for the wind and water sensors, an IS70 multifunction display, and a new wheel pilot bundle. Use an iPad for a chart plotter and don't worry that it's not linked to the rest.

Next in importance is an AIS transceiver with Axiom chartplotter. This is an almost indispensable safety aid. We use it actively every time we sail.

Last, if you can endure the expense and pain, get a below decks A/P. Not easy to install in a Catalina but lovely to have.

Finally, whether you have a wheel pilot or belowdecks A/P, a rudder position sensor greatly improves the accuracy of the A/P.  It's included in the below decks bundle, not sure about the wheel pilot bundle. (You can save a ton of money buying kit bundles rather than individual components).

Radar is used the least. But on one night passage with thunderstorm cells all around it was massively helpful and allowed us to steer a passage between them.

I'm 99% certain that the emulsified oil is the result of a failed seal in the water pump. That old pump is completely and utterly shot. I'll check the inside of the rocker cover, of course. Hopefully there's been no major ingress into the engine block.

Haven't done them yet KW. Been away a lot recently. Hopefully, I'll get back down to the boat within the next two weeks.

But first, I've got a good bit of work to do including: cleaning the land, investigating the emulsified oil, repairing the camshaft slot and replacing the cooling hose with its almost rusted-though hose clip.

Then remove the HX and descale, replace aging hoses and replace the leaking exhaust hose. Should keep me busy during the winter🙄

It really pisses me off that the PO let it get to this state. I went across Biscay twice with this heap of junk last year. 50 hours of motoring and it could have failed at any point.

The trouble with finding a problem like this is the loss of trust in the boat. Now I'm wondering what other vital maintenance has not been done. Really, the only option is to go through the whole boat and replace every lifed item that I can't personally account for.
