Wanting to rig 2x head temp gauges
G'day everyone, I've had a very reliable run with my old 2.4 Laser in my ski-boat so I figure I should do the responsible thing and rig some gauges so I can actually keep an eye on her properly!... I'll get a new set of Teleflex gauges and I'm just unsure of how to rig the temp gauges. I understand it's not a bad idea to have a temp sensor for each head (do it once do it right y'know!) - just not sure whether I should be monitoring water temp (tapping hole into heads) or fitting temp sensors into the factory plugs/holes in each head... which is preferred, and which sender units should I be using?
Thanks in advance guys

Whichever floats your boat. I prefer just behind the thermostats.

If you want to run 2 head temps I would tap for water temp that way you can still run the head sensor for the alarm. Just in case it gets hot and you not watching the gauges.

They make a head sensor with the alarm and the temp readout function in one unit. For a 3 liter motor like an opti? Not 100% sure it works but should..http://www.ebay.ca/itm/Temp-Sensor-4...tZzBIT&vxp=mtr

The sensors go in place of the spark plug washer. one on #5 and one on #6 should keep you well informed.http://www.aircraftspruce.com/pages/...robes/gem6.phpLast edited by dwilfong; 12-07-2017 at 02:28 PM.

I see! 2 gauges in the one is a tidy/simple way of doing it for sure. I'm looking to use the sierra gauges I've bought though (finally doing a nice gauge set and stainless gauge panel to make it all look swanky)

I did wonder if 2 water temp gauges might be a little overkill, but they're ordered now... Will investigate those little temp probes though, would be cool to see if I can run them with the sierra gauges to show head temp without having to drill into the head, J type thermocouple has been mentioned for both I think, would be interested to see if the resistances are similar/compatible
