I have a 1985 Evinrude V4 VRO 140. The Water Control Valve is pissing water out continuously.
The parts are no longer being manufactured.
Here are the parts:
Evinrude 0394407 (entire valve)
Evinrude 0330262 (wiper)
Evinrude 0329787 (seal)
Q1 ? If the seal is pissing water, is it probably just the seal that needs replacing? Dusky has one for $15 + S/H.
Q2 ? I have heard and read on-line that the valve can be bypassed. I live in SoCal, so not dealing with cold air or water, if that means anything.
My understanding is that at low rpm the valve is open and creates pressure on the thermostats to keep them from opening, thus getting the engine to ideal running temp faster. When the throttle is opened up, the valve closes, removing the pressure, allowing the thermostats to open up, and cool the engine. Seems reasonable, but I am not a mechanic or engineer and probably misunderstand.
Does anyone know if the valve can be bypassed? It doesn?t make sense to me that a valve Evinrude engineers into the engine can just be removed. If it was something there for colder climates, it might make more sense.
Do the thermostats need to be changed if the valve is bypassed?
Does anyone know how to bypass the valve?
There appear to be three hoses involved.
1[SUP]st[/SUP] ? Narrower hose, lower unit <---> valve
2[SUP]nd[/SUP] ? Narrower hose, cylinder 1 <---> valve
3[SUP]rd[/SUP] ? Fatter hose, tell-tale <---> valve
