25 hp primer

[caper_45ca]

I just bought this boat and motor....1995 25 hp evinrude mod E25REOR.....Also ordered a manual from Kencook...will b here Tues....in the meantime does anyone know the correct operation of the primer on the front of this engine....I was told to pull all way out then all way in then out to red line and start??????after starting push all way in....is that correct?...also is this used to fast idle this engine?????If not how?

I too would like to know the cold starting procedure with the primer, I have a 93 Evinrude 30hp, rope start.

Re: 25 hp primer

All a manual primer will typically do is draw fuel from the carb float bowl area, and pump it into the throat of the carb. This direct shot of fuel into the engine works far better than a choke butterfly, and you get better airflow thru the carb with no choke assy in the way. The primer does not control the throttle linkage to affect idle speed.

As a rule you'd pump up your fuel hose primer bulb until it's hard. Then, a couple of pumps on the primer and push it all the way in. The primer should remain fully in during normal operation.

Make sure the gear shift is in Neutral, open up the throttle a bit and crank the engine, it should fire right up. If a bit cold-blooded, try another pump on the primer. Note once the engine's warmed up you shouldn't need to use the primer, if you pump too many times you could flood it out.

BTW, check out the BRP site for official parts listings with diagrams:

I have a 1987 Johnson 20 hp and it took me a while to figure out the best combination of pumps. For me its 3-4 pumps with the primer and leave it out (at the red line). Crank the engine and it should fire. Once it fires, I give no more priming even if it dies. I push the primer back in when the motor starts idling well on its own.

Re: 25 hp primer

Ok thank you for the suggestions.....I forgot mention that my motor is not tiller controlled it has a remote and if I move the control to add throttle the engine will go into gear.....this is why I was wondering about the fast idle....Does leaving the primer out a bit help with engine warm-up or even increase idle during warmup?
