engine repeater instruments?

I can't easily see tachometer, oil pressure and engine temp. from the wheel, and would like to install repeaters in the cockpit.

1. I should be able to use pretty well any manufacturers units for these, no?
(engine is Volvo MD 17)
2. Do I need special dual sending units on the engine, or can I just add another set of wires from present instrument to the new one?

I am thinking this should be a straight forward installation - am I missing something? (nothing on my boat, other than the skipper, is simple!)

Any ideas or advice from those who have done this would be much appreciated.

The tacho can generally be paralleled. but the oil and temp senders need to be changed for dual sender versions . Alternatively cruise pro offers a buffer amplifier to allow their electronic gauges to be used along side existing analog gauges.

Thanks Dave!
If I get dual sending sensor units of the same make as the gauges, they should obviously be compatible with each other. Will they likely have the same thread as the old sensors? ie., will they screw into the block of the Volvo MD17?

yes , they will fit in place of the others. Note that in some cases , there is a warning switch and a sender integrated into the one sender, in the dual senders, the warning switch may be absent. on most boats the warning switch sender and resistive sender are separate.

I did exactly what you want to do , several years ago, no problems .

Dual Station senders have half the resistance of single station senders, but are mechanically identical.
