110HP Evinrude

[89commander]

Hi, I just bought my first boat, 1989 commander with 110 HP Evinrude V4 outboard engine, I toke it to the lake for the first time, it start ok and was cruising very well for half hour, then I stopped and set the handle to idle and after few seconds the engine stopped, I tried to start and it didn't, a high smell of gas was in the air, I waited 15 minutes and tried but it didn?t start, I waited 15 minutes and tried again but it didn?t start, I was towed out the lake and when I pulled out I noticed that there is gas mixed with oil leaking down the propeller, it was constantly leaking all the way to the parking area, it slowed down later but didn?t stop, after driving back home, it looks dry, I tried to start and it started right away.
I was using 87 octane gas???
I need advise.
Thanks - Solly

Re: 110HP Evinrude

The engine became flooded with the fuel mixture. The 87 octane gasoline is fine. Remove carburetor face plate, pump fuel primer bulb up hard. If fuel leaks/flows from carburetors, they will require cleaning and rebuilding.

Check to see that the fuel primer solenoid RED lever is in the proper position as follows.

(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.

Re: 110HP Evinrude

Sounds like a stuck float or trash in the carbs. Did the motor sit for a long time without being ran? You need to verify where the gas is coming from.

Check your primer solenoid to be sure that the small red handle is aligned with the cylindrical part of the solenoid.
