Own the boat
for short time.
Temp gouge with moderate engine
load shows 225F - no way. Confirmed with temperature gun - 180F. Thermostat original Perkins
was placed by me and temperature reading shows it opens properly.
Now, before ordering a new temp sender did some measurements.
has two instrument panels
in pilothouse and cockpit
temp is 60F(18C)
Temp sender connected - gouge in pilot house shows 72C - in cockpit
Temp sender disconnected - gouge in pilot house shows 60C - in cockpit 70C
It seems they consistent to some degree - shown temp drop 8-10C
The sender resistance 400 Ohm - Ouch... It seems should be 240 Ohm and dropping when the sender warms. No?
Checked sender wires going into contact panel which splits into two (one for pilothouse - another to cockpit - no issues. Cleaned the sender contacts - no effect.
Both gauges shows temp (see above) when the sender disconnected. Normal??
Parts4Engine says "This will not fit directly into to a Perkins 4.108
unless you have a reducing adapter. " See picture attached. Is there adapter?
May be someone can point where I can get the sender in USA (with part number)
And thank you for reading the entire post.
May be you can advise something else?
