    • Is an EGT alarm a better overheat indicator than coolent temp.

      This topic has 12 replies, has 7 voices, and was last updated by Dan 2 weeks ago

      January 28, 2018 at 5:10 pm I’m considering installing EGT gauges with alarms to augment my coolent temp gauges/alarms. I’m thinking this is an overall better heads up that things are heating up. I’ve read that if you lost all coolant (blown hose) you may not get an alarm due to sensors no longer submerged in coolant. Am I thinking corectly? Is it worth installing these? Any strong opinions? Thanks! Joe

      Reply #12 February 1, 2018 at 11:04 am Bill, I’m no where near the boat at this time,so I can’t reference my records -from memory the impellers where under 150 hours,around six months old,the other one still hasn’t been changed. The one that failed was the one that picked up the oyster shell, damage was probably done then. Rob They have served me well,for under two hundred dollars they certainly have paid for themselves,yes its a pursuit- speed is in MPH.

    • Analog to NMEA 2000 converter/network

      January 9, 2018 at 11:55 am I will be upgrading my electronics to Simrad Evo3s, and want to display engine information on them. I have 4BTAs with VDO OceanLine gauges that work great and I want to keep them. I assume I will be setting up a small NMEA 200 Network. I am looking at the following converters, VDO Aqualink, Noland RS11, AlbaCombi, Actisense EMU-1. Does anyone have any experience in this type of an install or have used any of the units I mentioned. I’m…

      Reply #2 January 22, 2018 at 9:34 pm I installed a Noland MD33 for dual engine analog (directly from the analog gauges) to NMEA 2000 conversion on my mains and a Noland RS-11 in the engine room to send gauge data from my generator and turbo boost sender to the NMEA 2000. Works great. It requires some fiddling around to calibrate but once you get the hang of it it works very well. JBB

    • Bosch K1 Alternator wiring

      This topic has 8 replies, has 2 voices, and was last updated by Tony Athens 1 month ago

      January 3, 2018 at 9:45 pm What is the D+ lug on the K1 Bosch alternator for? It was jumped over from the B+ lug when I inherited this boat. It had a parasitic drain on the battery that was identified as the alternator. First suspicions and advise was that a diode was bad. But, I am now thinking the jumper wire from the D+ lug was the cause. I “now” understand this to be the field exciting lug also used in conjunction with a charge indicator light. The light f…

      July 22, 2017 at 5:10 pm Cummins had to replace my QSB 5.9 engine and put a Recon in it this last week. All seems to be fine. They very nicely gave me a version 3 VesselView as I didn’t have one in the boat. We connected it for the sea trial and it all worked fine yesterday. Today, shortly after starting the engine I got the “sim no J39 data” error. When this occurs, don’t get any rpm reading, either on the VesselView or the original tachome…

      November 25, 2017 at 3:38 pm I’m about to install a pair of SMX Digital Voltmeters to a pair of 8Ds. I’m installing home runs +/- for both but…… Both batteries go to a common ground bus, from which the whole boat is grounded. Is there any value to having one of the DVMs have a switched negative which goes to the ground bus so I can see the difference between battery egatuve and ground negative?
