Yanmar 6lpa Stp Gauge Questions

Discussion in 'Boat Mechanics, Technical Help, etc' started by saltydoc, Feb 17, 2021.

    My new to me Yanmar 6LPA-STP motor with 180hrs came with an older an minimal "Type B" console panel- which includes a tachometer and 4 0r 5 alarms(water temp, water in fuel filter, oi pressure, and boost/ EGF- I think).
    Anyway I ordered some new gauges for:

    -Water temp
    - Oil pressure
    - Voltmeter

    The motor came with a variety of switches, senders, and sensors installed- and attached to the motor electrical harness- BUT not all to the dashboard panel.

    So how do I hook up these gauges and to what?

    A regional Yanmar parts guy says he can get me a Type C/D harness that has temp and oil on it for easy hook up....for$600 yikes. Can't I just trace the wires and do it for cheaper myself?

    what about this Boost sender- can I use it on new gauge?

    I love this motor but hooking up gauges seems a lot harder than it should be.

    Wow! That will be nice once you get her all hooked-up. Sure wish I could be of help. Maybe someone else here will be able to. It is surprising that gauge hookup would be such a PITA. Good luck and let us know how it turns out.

    You can keep what it came with or purchase a new C panel.

    I would check with surplus unlimited to see if they have a used one. if not I would buy a new one.

    so you can look someone that knows how to install separate gauges. I would only use an OEM panel so you can see what is going on with your motor. plus it has safety features built into it.

    since you motor it is new to you, I would take out and inspect all your zincs. replace if needed.

    I would also flush it out with barnacle buster or RYDLYME Marine Biodegradable Descaler

    I would clean up your motor then spray with corrosion blocker.

    Good luck.

    Thank you for your help. Of course every boat purchase is a compromise. The boat is a beauty and the engine has low hours- and the surveyor appropriately recommended to install gauges.
    I just didn’t know it would be such a pia.

    Short of a major dash revision I don’t believe there is room for a C panel. I was planning to build a panel up from original with gauges.

    Nope no room. where do you live? check out the surplus boating supply houses for gauges. we have one locally which seems to have everything. Its called surplus unlimited on SR 92 in Daytona.

    Thank you! Solid hand made Maine built!

    Yes- plan to flush engine this spring then install new zincs added to my list.

    I’ll check out the supply places thanks.

    What about new temp/oil/boost senders in place of old ones with appropriate BSM to NPT adaptors?
