...sorry - I should have mentioned that I also have a M-35B.

Sounds like your tach is off.  My tach is other have suggested, I used a laser hand-held tach.  When my tach reads 1100, the laser read just about 1600.  I've got a Gori 15x9 RH folding prop which has an over-drive feature.  When over-drive is engaged, I can do close to 7 knots at about 2000 RPM (again - tach is off, so this is an estimate).  If you're thinking about a prop replacement, I'd recommend the Gori.

Hope this helps.

Jim - that looks amazing.  I've been thinking about doing this for some time.  Are there 'battens' going horizontally across the shade to give it some shape?   :clap

Never had to do it, but if I did sink to head and back is one way.  I might be inclined to go from the sink thru the back of the bilge - past the holding tank following the sanitary tube (behind the head) and then along the port side of the boat (under the cockpit locker) assuming your 1998 layout is the same as my 2000.

Geo : Have you looked at exhaust hose? Shields makes some that is wire reinforced with an ID of 1 1/8".

A thought
Ron - 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...

As far as electric winch handles go, have you checked out eWincher:  Expensive, but seems to do the job.  Might be cheaper in the long run than installing electric winches and less to worry about as far as on-board power management goes.

Iím standing in my boat looking at the hose is question now. I measured the OD as 1 3/8Ē so youíre measurement of 1 1/2Ē isnít far off. The hose I used when I replaced the coolant lines a couple of years ago is Trident #100 0780 7/8Ē diameter. Thereís an SAE mark on it but itís smudged and I canít 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 nothingís easy on a boat!   :D
Dave - 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.

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 ?

A thought
Ron - that's it - looks like a pre-formed wire-reinforced hose.  Its painted so I can't read any specs on the outside.  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.

ANother view of the hose in question...

Hi again - I am struggling on the short hose from the manifold to the thermostat (see picture - the one with the arrow pointing at it).  A couple on this forum said its 7/8" ID.  The OD is 1 1/2" so I not sure this is right.  Unfortunately the hose is painted so i can't see any markings.  I called Catalina Direct tech support.  They do not stock this part specifically, but said 1 1/8" is the ID.  No one in Toronto seems to stock that diameter hose - its very rare.  I've gone thru my manuals and can't find reference to any hose diameters.  Any thoughts?

Universal M-35B; Hull #1494; built 2000.

Thanks in advacne.

Ron, Dave - thanks.  Very helpful.

Geo : I believe that the specs will give you the diameter, but not the length.  The raw water hose from the pump to the HX should be nylon reinforced so just roughly measure, then add an inch or two and you should be OK. 

On my M25XPB engine similar to the M35BC, I took both the inlet and the output hoses from the raw water pump and ran both of them up from the pump directly aft on the upper port side of the engine - one to the HX and other (inlet hose) around the corner to the thru hull.  I incased both in a piece of clear plastic water hose (a conduit) to protect them. That way I could easily change my drive belt without having to remove hoses.                   
Something to think about!!   :thumb:

A few thoughts

Ron - thanks.  I'll check again on the diameter spec.  Length I am ok with.  the hose from the manifold to the thermostat is short - but it's "painted" so can't see the ID/OD.  I'm ok getting them a bit long and cutting down if needed.

Hi - quick favour to ask.  I need to replace a couple of hoses.  I've got a M35-B.  The (short) hose from the manifold to the thermostat and the hose from the water pump to the heat exchanger.  I need the length and diameter of the hoses - I could take them off an measure, but would prefer not to take them off until I have replacements at hand (if I take the existing ones off I am not sure I'll get them back on).

Does anyone know the length and diameter of these hoses off hand?  I could not find these specs in the manual.

Thanks in advance.

Bacon Sails is a good place to buy and sell used sails...even if you want to sell privately, it might give you an indication of price.  Check them out online.  You simply enter your boat make and model and you'll get a list of their inventory and condition of the sails they've got. 

Hope it helps.

Where is the crankcase vent hose run to - the air intake I presume?

Yep - right to the air intake (air filter).  The problem does not seem to be getting worse...more detective work needed...

Thanks for all your advice.
