Hello, My name is Bryan. I am from WV and I have just acquired my first boat. Its an old one but is in decent shape. Its a 1986 Crest 25' Pontoon, with an 1986 Evinrude 50 VRO.( Model E50BELCDE). It has been setting for at least the last 10 years, but was started every year. I went today and bought a new fuel line with pump bulb, new fuel mixed to 50:1. Hooked the battery up and cranked it over. It took it about 5 minutes of cranking and I finally got it running. It runs good, or at least to me seems to. The previous owner had done the steps to disconnect the VRO. I will post some pics of the motor and boat tomorrow, but I have a couple of questions. There was an alarm that went off after i had it running for about 15- 20 minutes at an Idle that seemed to come from around the key switch area. I assume ( from reading about the VRO online) that this alarm is connected to the VRO as some type of oil warning. If it is disconnected what would make it go off???. Also I noticed that the primer solenoid had to be turned towards the front to get it started. what is the correct way for that to work. I will eventually have to take it apart and replace an O-ring that is on the red knob as I noticed it was leaking when i turned it towards the back. I read on a post earlier that the solenoid works by pushing in on the key, I didnt know this, and thats why I joined the forum so Maybe you guys could offer some knowledge and advice to a new boat owner. I have a small history with boats as my parents had numerous when I was growing up But I just turned the key and drove it, never had to work on one. So Here I am... LOL. Sorry for the long winded speech, But am anxious to learn .
 
Ok change the impeller? you mean for the water pump? it is flowing a pretty good stream. I did have a couple of splits in the water line . and I fixed that. Ok stupid question, again Im new to the technical terms, but what are the zerts? where can I get a manual for it. Thanks
 
(Fuel Primer Solenoid Function)
(J. Reeves)

The RED lever...... The normal operating/running position is to have that red lever positioned over top of the solenoid and aimed at the other end of the solenoid, gently turned to its stop. This is the normal/automatic mode position. Pushing the key in opens the valve within the solenoid allowing fuel to pass thru it in order to prime and start the engine. Looking upon this solenoid as a electric choke results in a better understanding of it.

Having that red lever turned in the opposite direction, facing away from the solenoid, allows fuel to flow thru it to the crankcase area. One would only turn the red lever to this position in a case where the battery might go dead and the engine had to be started via the rope pull method. Look upon putting the red lever in this position as moving a choke lever on a choke equipped engine to the full closed position. Either one would supply fuel to the crankcase/engine for starting purposes BUT if left in that position while running would flood the engine.

The later model primer solenoids are equipped with a schrader valve, used for attaching a pressurized can of fogging oil etc, available at your local dealership with complete instructions.

Pumping the fuel primer bulb up hard fills the carburetor float chambers of course, but that process also applies fuel pressure to the primer solenoid.


The two small hoses leading from the primer solenoid branch off via tees to each fuel manifold section that would feed fuel to the individual cylinders.


Pushing the key in activates the primer solenoid to allow fuel to flow thru it to the intake manifold passageways. Cranking the engine over causes the fuel pump to engage which in turn sends fuel pulses to the primer solenoid via the 3/8" fuel hose.


Some engines incorporates the "Fast Start" feature which automatically advances the spark electronically so no advance of the throttle is required for starting.
Engines that do not have the "Fast Start" feature will be required to have the throttle advanced slightly.


Starting procedure: pump fuel bulb up hard, crank engine and push the key in at the same time. When the engine fires/starts, release the key so that it falls back to the run position.


Bottom line..... Look upon the primer solenoid as an electric choke.

Thousands of parts in my remaining stock. Not able to list them all. Let me know what you need and I'll look it up for you. Visit my eBay auction at:

(Proper Starting Method - Fuel Primer Solenoid - Choke Butterflies)
(J. Reeves)


Cold Engine: Pump fuel primer bulb up hard. Increase throttle somewhat with whatever type control you might have UNLESS your engine is equipped with the "Fast Start" feature. Turn key to start position. As engine cranks over, push in key to activate the fuel primer solenoid OR to close the choke butterfly(s). (Fuel is drawn into the crankcase with every upward stroke of the pistons).When engine fires/starts, release the key. Should engine start to die out, push key in (just a tap) as needed to activate primer solenoid OR choke butterfly(s) in order to momentatily increase the fuel flow.


Warm engine: Pump fuel primer bulb up hard. Turn key to start position. When engine fires/starts, release the key. If engine does not fire/start within 6 revolutions, push in key to activate fuel primer solenoid OR choke butterfly(s) as needed.


This is assuming that the engine is as it should be in all respects (Compression, Ignition, Carburetion, Fuel Supply, etc).
 
Thanks alot Joe. Makes since now that you put it like that. I went and took some pics of the motor and im gonna upload them here in a little bit. I am far from a mechanic and classify myself more as a parts changer. meaning that I have a little bit of mechanical knowledge but not alot. LOL While I was down there I turned the key to see if I can hear the click that this solenoid makes. I hear it in both positions, Is that correct?. I will have to take it apart as it leaks fuel out from the red lever when it is in the Back position. I have looked at the parts diagrams on this site and see there is a o- ring in there. Is that hard to change?
 
50hp6.jpg50hp4.jpgIn this position is when it leaks fuel. comes out right at the red lever. Can someone point out where the thermostat would be on this? what do I need to takeoff to get to it?
