Does anyone know how the hull is built? Assuming there is a core. What material? How many layers of glass? Mine is a 34 Mk II - hull 1494 built in 2000.
Thanks in advance.

Geo : I've stored the boat with the mast up for almost 30 years with no problems.
FYI, when the boat is on jack-stands or in its cradle; there should be 75% of its weight on the keel and only 25% of its weight on the jack-stands.
The jack-stands should be positioned at bulkheads to maximize support!!
I can't believe there is any strain on the standing rigging with no sails up??? The only advantage that I know of with the mast down is the lack of wear on the wind instrument (can be locked to not turn) - otherwise it is always turning with the mast UP!!
A few thoughts
Quote from: Ron Hill on August 26, 2020, 02:27:44 PMRon - good thought - thanks. I've been doing more digging. Catalina Direct shows the hose I need for a M-25 being 7/8" ID and 7" long. They do not list the part for the M-35. When I called Catalina Direct, they tolf me the hose is 1 1/8" ID. I got in touch with Westerbeke and they say (backed up by a technical diagram) that I need 7/8" ID and 8" long. So appears contrary to what tech support at Catalina Direct has told me. Seeing if I can source some 7/8" ID hose locally...although I would not have believed it is 7/8" ID since the OD is about 1 1/2". Once I get this solved, I'll contribute a wiki article on the subject...
Geo : Have you looked at exhaust hose? Shields makes some that is wire reinforced with an ID of 1 1/8".

Quote from: Dave Spencer on August 25, 2020, 05:56:36 PMDave - thanks. Sounds like we're talking about the same thing. Catalina does not seem to stock a hose described as "Manifold to Thermostat" for the M-35B (but the do for other engines). I called Catalina tech support and they explained they are only starting to supply replacement hoses. They said the ID on my hose is 1 1/8". My local engine parts supplier (biggest in Toronto) does not even stock 1 1/8" since its so rarely used. Catalina Direct DOES stock a 1 1/8" hose described as "Manifold to Heat Exchanger" (Part #: Z5049). Wondering if that might work. I'll certainly take Ron's suggestion and call Westerbeke.
Geoffrey,
I'm standing in my boat looking at the hose is question now. I measured the OD as 1 3/8" so you're measurement of 1 1/2" isn't far off. The hose I used when I replaced the coolant lines a couple of years ago is Trident #100 0780 7/8" diameter. There's an SAE mark on it but it's smudged and I can't make it out. SAE J??06.
I have an M35A, not the M35B that you have but I highly doubt there would have been a change in hose size here.
Should be easy but nothing's easy on a boat!

Reason I thought to replace it is it's looking brittle around the hose clamps - looks like some cracks - but it could be the paint cracking. I am nervous to remove it to inspect it in case I can't get it back on and not get a replacement. Good suggestion - I'll try Westerbeke.
Geo : From the illustration it looks like that is a wire reinforced or a pre formed hose. You might give Westerbeke a call @ 508-823-7677
Why are you replacing that hose ?
