    Be aware of what your engine actually provides.

    It disappointed me that the my Volvo D1-30 had very little sensors. Coolant temperature, RPM and engine hours were all it provided on the canbus iirc. (maybe alt voltage... ) 

    In hindsight I found it an expensive investment for having those things on my mfd. Had I known all I was really getting was temperature, I would of opted for a analogue Volvo temperature dial. 

    Oil pressure, oil temperature, coolant pressure would all of made it far more worthwhile, but the sensors aren't there... 

    Thanks for the feedback, your on my page, is this a cost effective method to get those three primary data.

    Seems pretty straightforward, but what's the benefit on a small yacht?

    I have a basic network with 2 displays, why not use them , I don't see size matters. I'm blind now except for a audio alarm.

    Hi 

    Many of us now have NEMA2000 displays but 20-30 yr old motors, with little monitoring beyond the control panel. That is no NEMA2000 output.

    Has anyone experience with the units available from Aliexpress, see picture. It appears one maybe able to get rpm, oil pressure and temperature, plus tanks onto a network.

    Are there other options, I'm aware of Actisense EMU.

    Thanks

    Maybe some more detail of the unit on your boat?

    I had a similar experience backing out of a marina berth in Havlock, collected two launches an a pile in the process. Not a nice feeling!

    Turned out to be a cable clamp, bracket that had come free from a mount on a bulkhead next the the motor. Allowed the cable to bend without moving the lever on the gearbox. Nothing to do with lever in cockpit.

    Check out some other Aquarius 22 trailers. we have a couple in our area an they do not struggle getting them on the trailer. As mentioned above be aware of over loading the winch wire/rope, the S hook an D on the boat.

    Another Rangitoto question.... salt springs?

    @Ex Machina That map is of the Auckland Volcanic Field, your totally correct there are volcanics elsewhere. However the South Auckland Field is much older and classed as extinct as is Whangarei. The Northland Volcanic Field is a little harder to class as there are events around 40,000 yrs ago .... probably on its way out.

    Outside of the greater Rotorua-Taupo area (Taupo Volcanic Zone), we can only map molten rock under the Auckland area, at about 80 km depth.

    Totally agree the next eruption in Auckland will not be a lot of fun.

    Thanks IT for reading .... 

    The attached image is from a paper dating events in Auckland ... eruptions started about 140,000 yrs ago and last was Rangitoto (600 yrs ago). Locations are random (oldest and youngest are basically next to each other. The rate of eruptions has changed with time, but was really busy around 30,000 yrs ago (an average rate means very little). As mentioned all the volcanoes have erupted once, except Rangitoto which has erupted twice (the 1st maybe about 6,000 yrs ago).

    Eruptions are very unlikely to occur outside of the area shown on the map (left side).

    Where next ... toss a dart at the map ...
