hi fellas
i recently brought a go-kart two stroke digital temp sender unit to put on my late model 50 hp short shaft 3 cylinder/3 carb mercury (tohatsu) engine.
i have tried 2 different locations to put the sender unit in,one in the cooling jacket of the middle cylinder head and another location in side of block where water outlet goes thru.
it only reads approx 18 degrees celcius!!
i did a test to check sender unit working properely by placing it in boiling water on stove,it reads close to 100 degrees celcius boiling point,so the guage is working properly.
so where should i position the sender unit correctly to measure engine temp please ???
thanks
glen
