Jw-22 gearcase

Ok, no matter what I do this will not sit flush, seems like it will if I tighten the screws, is that normal? The shaft did not seem bent when I cleaned it up.

It could be your water tube isn’t sliding into the pumps grommet all the way. The tube should be sanded clean and lightly greased to help it slide in. Don’t force it as the tube is soft and will bend easily and might rub on the driveshaft, causing a major leak. Before assembling it, take a peak up the exhaust housing to make sure the tube isn’t bent. If it is, it can be straightened out with a wood dowel before putting it all back together.

It is most certainly bent, I thought it was supposed to be, I’m guessing I need to remove the entire power head to fix it?

no chance that extension is upside down would it ?

Don’t know, this is the first outboard I’ve really dug into, most of my small engine stuff has been on chainsaws.

It’s probably easiest to just remove the powerhead so the tube can be either straightened or replaced. But, you may be able to get up inside there to straighten it out, perhaps pulling the extension off will help…

Good question, but I don’t think it can be installed upside down…One side has threads for the gearcase screws, the other side has open holes….

Notice the big gap at the aft end of the open space. The drive shaft in not entered into the crankshaft.

No, just reach in there with a stick or a dowel or something and you should be able to straighten it out. It is tight in there but you can do it without removing the powerhead.

try to slide a 1/2 inch pipe over it and bend it back straight as you progress towards the PH ….might work
