1975 135 johnson loose water tubes

[boatwrecker]

I recently replaced the water pump on 1975 johnson 135 i noticed when installing lower unit back on that one of the water tubes going to the water pump housing was very shaky or loose and the other one was pretty steady what would cause this any need for concern also how are they connected to the engine

Re: 1975 135 johnson loose water tubes

are you referring to the guide tube?...... the little short tube that connects the water pump to the main pick-up tube.

if so it will be a little loose.... otherwise it would be more of a pain to align. you dont want it to fall off during reassembly though.

you can get complete parts descriptions and exploded diagrams here http://shop2.evinrude.com/ext/index.aspx?s1=9c60db3eafc1f4b20ccd2da688b6ec1c

It really doesn't matter how loose or tight they are as long as they are in the right position in the pump housing when installing the lower unit. The tubes are merely there to facilitate assembly. As long as the water tubes to the powerhead sucessfully slide into the water pump housing, you're fine.

Somehow we seem to be assuming you are speaking of the plastic guides. However, when I read the question, it seems that you are asking about the water tubes' attachment at the upper end.

They are attached to the bottom side of the powerhead adapter by a flange. There are two rubber grommets making the seal complete. If it is loose and shaky enough it would indicate the rubber grommet is shot. But if it just moves around in the rubber, it is ok. So the question arises: How loose is loose?

If the rubber grommets are shot, it is a major job to replace them. The powerhead has to come off. Then the midsection has to come out of the mounts. Finally, you can then remove the powerhead adapter to access the water tubes, retainer plate, and grommets.
