Also, take the grommet out of the water pump housing and clean the corrosion out of the housing. The corrosion build-up between the housing and the grommet will cause the water tube to fit too tightly and bend the tube, rather than enter the grommet.

Long live American manufacturing!

That much I did do already, got in there with a pick and a really small flat head, also had to fish out a phillips head screw I noticed in the water intake area forward of the pump housing. Hopefully have some time tomorrow to get back at that tube.

Also, should I grease the spline above and around the o-ring on the top of the shaft?

[frankr]

Yes, smear some grease on the splines

Notice my previous post. That is why it won’t go together.

[jeff-register]

Frank is correct BUT please no grease on the top of the driveshaft & replace the o-ring, it holds grease on the splines. Run it dry & iy welds itself to the crankshaft….bad news
Before retiring I serviced surgical tables. You would not believe cleaning makes assembly a breese. Take your time & get it right the first time.

[frankr]

To clarify, smear grease on the SIDES of the splines.

Ok, so, got the water tube straight and everything went back on, gear oil in, prop on, then I find this in the box under the other prop, might this be the “pilot ring” I don’t recall it coming out, but it has been a bit. Hard to tell where it fits in exactly from the diagram if that’s what it is.

It might be the washer which goes between the prop and the prop nut.

[crosbyman]

yep !! jw21 parts show a washer between the nut and front of the prop

There was a larger washer for that, been looking through the 67 and 59(donor motor) diagrams on marinengine, the lack of descriptions is not helpful
