Re: Stus-List Stuffing box leak rates
Bruce, Designed Aircraft hydraulic electric motor pumps, We used 20 drops per CC, which is consistent with 1.14 gal per day. The Phosphate Ester fluid used has a specific gravity of .975 so it is a little thinner than water but close enough. That said, if you a dripping at 1 drop per second you need to tighten up or replace the packing. We used a specification of 12 drops per hour on electric motor pumps running at 8,000 RPM.

Re: Stus-List Stuffing box leak rates
Per the web (?), a drop of water is 'defined' to be 0.05 mL. In this case, a drop/second x 86400 seconds/day = 4320 mL or 4.32 L. For my case (~ a drop/18 seconds), this is about 0.24 L/day--which is probably consistent with my bilge content when left without the pump working. Since I had the packing tightened about 8 months ago, it either needs retightened or the packing needs replaced, as suggested by another lister. It certainly is enough to fill my bilge if it is not pumped away regularly, especially when combined with water down the mast, etc. Thanks, Charlie NelsonWater Phantom1995 C 36XL/kcb -Original Message- From: bwhitmore via CnC-List To: cnc-list Cc: bwhitmore Sent: Sat, Mar 14, 2020 8:38 am Subject: Re: Stus-List Stuffing box leak rates Hi Pierre, I was interested in your comment and went to verify it, and found a huge disparity in results, everything from the 1.14 you mention to as much as 8 gallons per day, and some of those coming from seemingly reputable websites.

Re: Stus-List Stuffing box leak rates
Mine used to drip at a similar rate when at the dock (well, mooring), although I always left my bilge pump on (with a float switch). It dripped a lot more when underway. After repeated adjustment I couldn't get it any better so at the last haulout I changed out the packing. Now doesn't drip at all at the dock, and maybe 1 or 2 drops per minute underway. Suggest you change the packing.

Re: Stus-List Stuffing box leak rates
I use a PYI system and have not had a water leakage at the shaft. The water I get in the bilge is coming down the mast, because I mounted a hard vang as low as possible to the cabin top. Mistake because found it almost impossible to seal. However the seal I use does limit that problem until the heavy downpours. I do have a Rule separate float switch mounted forward (slightly higher) of the low point in my bilge with the Rule pump in the low point. I keep the switch "off" when not aboard since the boat is on a mooring and the last thing I need is a dead battery because the float got stuck "on".

Re: Stus-List Stuffing box leak rates
FWIW, The previous owner of my boat wired the bilge pump to a fuse to the hot bus. There is a float switch but no manual switch to accidentally turn it off. I close all the seacocks before leaving the boat and the shaft gland doesn't leak except when I first launch. It drips very little then and stops after a few days. The yard's diesel mechanic told me not to tighten the gland unless that drip continued for more than three days. He was right. I check the temp by hand on long runs.

Re: Stus-List Stuffing box leak rates
I leave my bilge system on 24/7/365. My Rule bilge float switch failed last year. I wanted to replace it with an Ultra Safety Systems switch. That switch had a week delivery time. I bought and installed another Rule as a temporary measure. Then when the USS switch came in, I drove 8 hours round trip to swap switches. That’s how serious I am about having an active bilge pump system on Touché. Even though I never expect the USS switch to fail, I keep the Rule as a spare. Dennis C.

Re: Stus-List Stuffing box leak rates
Hi Charlie, I replaced ours with flax/teflon packing about 4 months ago. It does not drip at all at the dock, and drips slightly underway. I can check the temperature of the stuffing box itself underway both by putting my hand on it (though the idea of having my hand near a spinning shaft doesn't make me comfortable) and using a laser thermometer. It does not get much warmer when running than when sitting, and I can certainly keep my hand on it without burning my hand. My old 27, however was much harder to get to not drip without it getting hot. Perhaps it had something to do with the small shaft diameter.
