Ron We installed the gauge on the advice of my mechanic who has been working on Yanmar marine engines for over 30 years. He is the local expert. I purchased a new sender unit and took that to a fittings supplier in our industrial park. The fellow at the counter picked out a couple adaptors and a Tee and had me set up in less than 5 minutes. There was no problem finding the matching threads. Total cost excluding gauge and sender was under $20. The gauge I purchased at Princess Auto.
Over the last two seasons we have motored a lot. We had taken the boat from Halifax, NS to Bras Dors Lakes and had just completed Baddeck Race Week. Mooring from Baddeck to Dundee at 2800 RPMS (30NM) we started hearing an odd clicking sound at approx. 3 NM from destination. Determined this was the pressure alarm starting and then stopping but not quite coming on full. After turning off motor and sailing into our friend's dock in Dundee we checked out the engine more fully. The first suggestion was to check the oil pressure. How do you accomplish this without a gauge? It should be just over 50psi. The next week we installed the guage and determined the pressure was just over 45 psi. So while the alarm was just cutting in the oil pressure was really all that low. New oil and filter and it was back up to approx 52psi I do not see how a brass gauge and fittings would suffer a catastrophic failure. Even if the gauge was to shatter or fail it would be simple to remove the sender unit off the other end of the tee and install it directly in the engine Mike From: Ron Ricci [mailto:rvri...@gmail.com] Sent: Friday, November 04, 2016 8:44 PM To: cnc-list@cnc-list.com Cc: Hoyt, Mike Subject: RE: Stus-List Oil Pressure Switch First, I checked out Mike's link and Persistence is a sharp looking boat. I'm partial to the color as Patriot is also dark blue with a red boot stripe and gold cove stripe. Patriot also caught a line around the shaft resulting in multiple B.O.A.T. units to straighten the strut and replace the shaft. I've been considering adding a the ability to read oil pressure by adding the appropriate transducer and NMEA 2000 interface. To me, the existing pressure switch setup is not necessarily 'fail-safe'. Probably the most difficult thing will be to find an appropriate tee (Japanese threads). I wonder if any other lister has found a tee that works with a Yanmar engine?
