Re: Stus-List 33 mk2 Mast step loads

Hi Greg, You can research the righting moment, at say 30 - 33 degrees, for various boats in your size range for a second opinion. The 33-2 is similar in stability to my 35 mk-1(check diagram in the Technical Info on Stu's CNC site). I put the load at about 10,000 lbs, so building for 12 -

Re: Stus-List Air in fuel line #2

My old Racor 220 was a 2 um filter, as well. Used it for 3 years without problem (other than fuel leaking from the plunger); though, I changed it annually. This might also be a question how much you are motoring (“annually” may mean 50 h (in my case) or 500 h is someone else’s). But no

Re: Stus-List Air in fuel line #2

I had a 2 micron filter 4 feet before the engine filter housing (had to pull heat exchanger to change it). Before the 2 micron canister filter was a 30 micron racors 500 filter.  Never had a problem with the engine fuel supply in 10 years. I always used Soltron when I got fuel. Only time I had

Re: Stus-List Air in fuel line #2

I've known full well that the 2 micron filter I run in my racor was much smaller than that which is recommended by the manufacturer or conventional wisdom. I always figured that the 15gph rating of my Racor 200FG was so much more than the required 1 to 2 gallons per hour that running a smaller

Re: Stus-List Air in fuel line #2

AFAIK best practice for a diesel is 10 microns before the fuel pump and 2 microns on the engine after the fuel pump. Passagemaker had a series of articles on this. Joe Della Barba Coquina C 35 MK I From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Gary Smith via CnC-List

Re: Stus-List 33 mk2 Mast step loads

Selden Mast Tuning manual (http://www.seldenmast.com/files/1416926327/595-540-E.pdf (p.31)) says that the shrouds should be set to 15%-20% of the breaking load. Keep in mind that you have at least 4 shrouds plus the stay and the backstay. The letter two are at less acute angle, so the force

Re: Stus-List Air in fuel line #2

I installed a vacuum gauge down stream of the racors. With new filters vacuum was almost nil, both at idle and cruise power. As the filters get dirty the vacuum will increase. Going to put a similar system on new boat.  Sent from my T-Mobile 4G LTE DeviceDoug Mountjoy POYC Pegasus

Re: Stus-List Air in fuel line #2

Another great idea from you- I already have a gauge on top based on a previous post to the list. Assuming the gauge is not leaking itself (a friend who installed one had problems similar to mine and it turned out to be the gauge was leaking!), I love the idea of testing the vacuum by closing

Re: Stus-List C 37/40+ holding tank

Alan, I made a rig to backflush the vent line. It consist of a toilet plunger and a 'poop' collector. The plunger is one of those that can hold a good amount of water. Here's a link to one: https://smile.amazon.com/G-T-Water-Products-Inc-MP100-3/dp/B0006IXNDW/ref=sr

What's the breaking strength of the upper shrouds? I'd think 50% of that would be conservative. Dennis C. On Mon, Jun 26, 2017 at 5:15 AM, Greg Sutherland via CnC-List < cnc-list@cnc-list.com> wrote: > Does anyone know what the maximum load would be on the mast step of the > 33? I'm trying to

Re: Stus-List Air in fuel line #2

Charlie, If you have room or if you relocate the Racor to where you have room, consider replacing the filter's T-handle with the Racor vacuum gauge. Not only will you know exactly when to change filter elements but it will provide you with another tool for troubleshooting a similar proplem in

Re: Stus-List Air in fuel line

Thanks Dennis--looks like the Racor is the likely culprit from your perspective. Whether that is the case in my situation or not, a Racor bypass sounds like a very good idea to quickly get fuel flowing again to get back to a dock. Thanks, Charlie cenel...@aol.com -Original

Stus-List Air in fuel line #2

Thanks for your responses. To answer some of the questions raised, the pumps were placed downstream of the Racor for a couple of reasons. 1. The pump original location was upstream of the Racor (30 micron) which was recommended by the Beta engineer because these small pumps do not have much

Re: Stus-List Air in fuel line

My experience suggested 4 likely culprits; Racor o-ring, Racor gasket, rough sealing surface on the top of the Racor body and bowed cover for the Racor. Put the Racor cover on a flat surface or use a straight edge across the cover. If it is "dished" downward, it may not be sealing well. If you

Re: Stus-List Air in fuel line

Potentially, only somewhat related... I had a problem with the Racor 220 (different type filter). It leaked fuel, not air. The source of the leak was the plunger in the pump on top of the housing. Eventually I replaced it with a SNAPP. Much easier to maintain (and it comes cheaper). No more

Re: Stus-List C 37/40+ holding tank

No problem. Just be careful with the counter top. The part that wraps around behind the toilet has a large lever arm and is relatively unsupported as compared to the rest of the unit. If too much stress is applied then stress cracks develop in the GelCoat. Its tricky to handle but not
