I recently changed the water
return hose on my 5411, its the one that connects to the underside of the thermastat and returns to the seacock via the tee at valve.
always ran extreamly cold with the gauge hardly moving, after changing the hose i noticed an increase in temp to around 140 or so.
My question is; is their air in the system now causing the slight increase in temp or was the old hose blocked or restricted and my system is now working as it should.
The thermastat and pump are new and all is in order as far as the rest of the system.
If it is air how do you bleed it, could i remove the hose and fill it with water
I took the boat out and ran under load for an hour or so and it stayed aroud 140 the whole time.
Am i on a witch here or is all COOL.
