Evinrude VRO V4 140 - Pissing water from engine.

[hbron]

Howdy all,

I have a 1984-ish Evinrude 140 VRO V4. It is pissing a stream of water from a round thing-a-majigger near the throttle control. See pic. Like to know what it is, what to replace, and how to find the specs/instructions on how to do that. Ive attached a photo. The stream is coming directly out of where I am pointing to, from between the outer most and 2nd concentric circles @ about the 11 o'clock position. It is a nice steady persistent stream at about 1/3 the volume of the tell tale when the tell tale is full-on pissin.

Think this is a looper 140- at least an 85.

Thanks. Yeah, as I stated above, it is a 2-Stroke Evinrude 140 V4 VRO - approximately 1984 (I do not know if it is a looper or not).

My request to forum members is to please have a look at the photo and tell me if you could what part my arrow (faded red arrow on yellow post it) is pointing to. It is pissing out water.

Does anyone know any forum members familiar with this motor?

Thanks for the help all.

Yes that is a looper style engine at about 120 cubic inches.-----That is a water control valve and it may need a new seal in that valve.-----Valve opens up when throttle is opened to allow more cooling water through the engine.---See a BRP dealer for parts .----Or see a dealer about getting rid of that valve.---Ask if there is a service bulletin on that.

Hey all, I hate to admit that it's taken me this long to get back at my boat engine.

I found out that the replacement valve is no longer available, and the neither are the two replacement seals if I wanted to try to just replace them.

Racerone, you mention the idea of getting rid of the valve. I have also seen and heard that you can bypass the valve. It seems odd to just be able to bypass a water control valve the manufacturer put there for a reason.

I read somewhere that the valve is there (and open) at low rpm to keep water pressure on the thermostats (at low rpm) to keep them from opening and thus let the engine get warmed up to and maintain ideal operating temperature when warming up, or running at low rpm's. Seems odd to me, since wouldn't the thermostats be temperature controlled and just do that on their own?

I live in So Cal, and do not operate the boat in colder air or water.

If I bypassed the WCV, are the existing thermostats able to control water flow through the engine on their own, or would they need to be changed out to reflect and modify for the WCV removal?
