Re: 1993 Evinrude Intruder how to instal Temperature Gauge ?
the threaded hole
if at the top of a cylinder head is the place to fit it.
I got a guage and sender from auto store and it fits and works great.
with a v6 or v4 I would buy 2 gauges and senders or atleast 2 senders anyway and have a flick switch to see what each side is showing.
the second sender can simply be fitted to the cylinder head by using a bolt and a simple z shaped piece of metal so the bottom of the sender touches the head itself.
the only problem is auto guages have the middle of the guage at around 88 degrees, and yours will normally run at around 55 to 65 degree's, so will be showing at around the 10 to 11 oclock position instead of the 12 oclock position.
I find mine is brilliant, and watch it all the time.
alarms only go off when its GOT TOO HOT ,
I prefer to know way before its toooooo hot...so to me a guage is the answer
