Hey Richard--I did complete the upgrade but have not posted photographs or even disclosed how I did it. Apologies to the Forum. I went looking for the photos but haven't located them yet. If I find them I will post again for the benefit of others.
I can tell you how I did it though. If you refer to my original post you will see three exploded diagrams. Look at the one that shows 9.3 Fresh
water pump. On my boat, those handy
ports that seemed to be perfect for the
installation of the sending units could not be accessed due to being blocked by brackets and/or hoses, belts, pulley etc. We had already determined (see various responses in this thread) that tee-ing off the alarm light sensor port was not a good idea. So I bought two new thermostat elbows and had them drilled and threaded to fit the new senders I bought. What I'm calling "elbows" are the cast
aluminum covers that bolt onto the
water pump, hold the thermostat in place and when the thermostat opens
route the hot fresh water from the block to the
heat exchanger. On that elbow cover is a flat spot that seems to be made for exactly this purpose. We installed the sensors then ran
single wires with inline
fuses to the gauges at the
helm.
I had the drilling and tapping done at a machine shop because I wanted it to be dead plumb and flat so it wouldn't leak. It worked perfectly.
The gauges are Stewart Warner part#82114 (also shown as 4000343). The senders are Stewart Warner part#280EA.
