  • fuel issues

    Came across an interesting problem on my johnson 225, seems it doesnt pump enough fuel at idle to always keep the carbs. full.

    changed filter cartridge, blew back thru fuel inlet to tank.

    The solution to this was to install an electric fuel pump up by the tank under the console. this comes on with the ignition. Now I dont even have to pump the ball to cold start the engine, just turn the key on, push the choke and it starts right up. The stock fuel pump is still in use (although the VRO side is disconected) dave

    I was thinking about doing that also, just using an inline electic pump that puts out about 5psi. Are you using an automotive pump or did you find a marine pump? if it's a marine pump, where did you pick it up and how much?

      Along those lines I have also thought about the same thing to help the motor pump gas from the aux deck tanks that I use when traveling outside the range of my built in tank. Would also be interested if its a marine or auto.

        Looooong Time ago. I painted a guy's ski boat. He had one of those inline 6cyl Merc outboard's on it. The only way he could feed all those carb's was with an elec. fuel pump.

          Its an A.C. Delco automotive. I cant tell the difference on the pulse pumps (auto-marine.) They are a sealed unit. No C.G. stamp.

          I hesitated to answer this because I dont want others to assume all fuel components from the auto world will be safe to use in the marine world. dave.

            M.D, how much did you pick the pump up for?

              I think it was around 30 bucks. Cant remember because I bought it a long time ago. dave.

                I'm thinking of doing that. My old suzuki can't sit for more than 20 min. or i have to pump the bulb to restart

                  This must a common problem in Johnson 225's. My Dad's 1991 does just that. SOB stalls out and kills especially when you are about to trailer and you shift forward to backward and so forth in idle. I notice it to be the worst when the motor is warm and the carbs don't have any choke engaged.

                    before I went and installed a suplimental pump I would have a helper squeeze the primer while idling to see if that helps. Cyclops there is a switch that kills 3 cylinders under the shifter arm on the starboard side of the motor. if that switch hangs up or is sluggish it will cause the stalling problem while shifting back and forth from forward to reverse. dave

                      MD, what do you mean the switch kills three cylinders? I've never owned a johnson.

                      When i had that stalling problem with my suzuki I ended up having to clean all three carbs. The orifices in those low speed jets were so small I'm sure anything could have clogged them. After a good cleaning, no more stalling. Just a possibility cyclops

                        The gears in the lower unit are cut on a angle and are hard to shift in and out of gear while presure is on it. By momentarily stalling the engine the process of shifting becomes much easier. Mercruiser has done this for ever. The switch I refered is called a momentary stall switch. on the OMC's it grounds out half of the coils. (stupid stuff learned the hard way) but I will say cleaning the carbs are always a good Idea. dave/

                          MD, I have the fuel pump a shot this weekend. I picked up a 5-7 psi pump from autozone for $30 and hooked it up to a switched power supply. It works great! no more pumping the primer bulb everytime i wanted to start the engine. Another great thing is that I don't need to keep the pump running at all times, just at startup. The only thing I'm worried about is corrosion, but come winter I'll just add that to my project list to paint that. []

                            I like that idea of no more getting down to squeez the primer ball every time you do a cold start. About thirty bucks - sounds like a plan.

                              Could one of you guys in the know, post a link to an appropriate fuel pump source?

                              I'm going to give one a try too.
