  • 1974 Chrysler 35HP Water Pump Question

    Should I be able to see water coming out of the center rear leg exhaust port exhaust while the engine is running? It seems to me that the exhaust comes out there and at the bottom above the propeller. I haven't seen anything coming out while running in a barrel. I am a newbie boater, so I appreciate your patience with this question.

    I just fired up my '70 55hp and it bubbled like crazy by the prop.

    Took a couple of good revs to get the water to start spitting out the exhaust pipe. I've been told that's just because it's in a barrel or garbage can.
    I kinda got the worried feeling too..

    But it could be that your impeller is shot.
    At least those aren't expensive.

      Thanks Buzz. This boat has been sitting for twelve years before I bought it (indoors at least!) so I am a bit nervous about the whole deal considering lack of marine experience. It is on a '61 Elgin boat, appearance wise the motor looks great, like new, the boat looks pretty good too.

      Maybe I need to get it running on the water, I hope. More questions to come I am sure. Thanks again.

        Before we damage the lower unit.

        If you look at the bottom of the lower unit.

        You should see a large screw, Should have "drain" stamped by it.
        Unscrew it and let a little but of oil come out. Let see what it looks like.

        If water pours out, then you have a bad seal. If the oil is cream color, then you have a bad seal. Here's where we would need to remove the lower unit and replace the seals. It's not hard, and the seal kit is only 19 bucks. Impeller is about 30.

        but bringin back a '61... In the same lake as I am.. '62 glastron for me.
        If you need a service manual for your outboard shoot me a PM and I'll get you one.

          1. Attached is a Pic of my 1970, 35 HP Chrysler (with a 55 HP cover) spitting with an impeller checked last when I purchased the boat in 1985.

          2. Attached is a Pic of my 1970, 35 HP Chrysler spitting with a new impeller this with a slight improvement. The old impeller was in good shape but peace of mind is better.

          3. My leg has to be fairly deep in the barrel for it to spit vs solid that I thought the new impeller would help. Not much difference and it has not overheated.

          4. Attached are pics of my L/U 2 seals replaced. I have posted other pics that a search on wickware should lead you to or ask about specific pics.

          Good Luck,
          JOW

            Great pics, thanks for the time and effort. Is it spitting the water at idle or something above idle? Mine is bone dry at idle, haven't gone past there yet, not that is running all that well yet. I did replace the fuel lines, cleaned and built the carb, put new plugs in.

            The picture really defines what I should be looking for. Thanks.

                I appreciate everyone's input!
                I will ground out the high temp sensor, can't get to it tonight though. At this point, it is a struggle for it to idle for more than 15 seconds, cleaned the carb are adj the float, simple carb. I guess I should see water flowing through the clear hose? Steep learning curve here. I will also ck for water contamination in the lower box. I am walking on egg shells with this one, I don't want to damage it either. Thanks, Joe

                    Re: 1974 Chrysler 35HP Water Pump Question

                    Thanks again Jow. Is it possible the water pump is not priming because it hasn't revved above idle?

                    The previous owner, the one who went to Sears in 1961 and bought this boat, took exceptional care of this boat. He bought the motor new in 1974 as well and kept it inside. He passed away in 2000 or so and didn't use the boat for a couple of years prior because his friend bought a bass boat.
                    I got the boat last week, it appears he drained the fuel prior to storage, the tank was dry and clean. The carb, initially the float stuck causing fuel to flow out the vent. I did disassemble and cleaned a very clean carb with carb cleaner but didn't soak it. I blew out all passages as well before reassembling with new seat and bowl gasket etc, not much in the kit. Put a new spring on the idle mixture screw. It has an .090 jet in it.

                    I will check to fuel pump as well this weekend. I did replace the fuel lines and primer pump as well. Believe me, I don't want to damage this engine. It does look new.

                    One more question: where do you get parts for this engine? I found the carb kit at napa, but where would I get the impeller, diaphram, etc. ? Do you have a source for older obsolete boat parts?

                    I really appreciate your help and advice, thank you again. - Joe

                          Sierra part numbers
                          • 18-3084 Impeller
                          • 18-3556 Thermostat
                          • 18-2636 Lower unit seal kit
                          • 18-7037 Carb kit (WB model carb)
                          • 18-7005 Carb kit (OM model carb)
                          • 18-7806 Fuel Pump kit ((6 bolt hole kit) Wickware has a 6 hole))
                          • 18-7805 Fuel pump kit (3 bolt hole kit)


                          All these can be ordered by Napa. My local Napa doesn't stock them.
                          But you can get them all here at Iboats. IF you want to shop around just search those part numbers. They are all Sierra Part numbers


                          Edit:
                          If you have to replace the impeller. Here's a small little tip when you unscrew the shift rod. You'll see a long nut and a short. Count the threads to each nut, then write it down on each shift rod. Saves a lot of time when reassembling.

                              I am getting the hint that I should just go ahead and address all the minor things before they become major issues! Considering the cost, I will go along with that.

                              I can't thank each of you enough for sharing your knowledge and experience with me. I really appreciate your advice. Each of you.

                              I am looking forward to tinkering and or tampering with thing this weekend. I hope to make some progress. I did check the part numbers and they are available at through NAPA, thanks for the guidence there.

                              I may try to see if I can find a restriction using the ports at the clear hose. More to follow later.
