Bada$$. Tanks for the assist Joe!

The card gave me rug burn I pulled it out of my pocket so fast. I was looking at either replacing the entire circulation pump and housing or trying to create a new one on the CNC.

everyone wants to complicate things… Listen zach…   I mean maybe ish. The marine parts diagrams showed a unidirectional brass looking impeller in the illustration similar to what you would find in a pcm circ pump for a small block ford – but called out the exact kit number I linked to, and the picture kit matches what he currently has. So maybe ? but is the business end of that impellor even raked or is it perfectly radial from the center? If its radial then it will pump the same in either direction, if its raked it’ll still do better than the no circ pump having engines that are running around all over the place.

I just didn't know how they determined direction with impeller design. I would agree with you if the blades aren't raked it should work reasonably well in either direction pushing water into the block.

Yeah CNC or laser cut the blank and form up the blades—better yet just get it 3d printed—wait—it’s only $50!

Chris—I’d definitely get the steel impeller e-coated.

Depends on what decal you put on

Buy 2 kits, don't bother coating. Change it in 20-25 years. You won't care after that.

Duane only builds from scratch.

Welcome to chapter 30.......The Wild World of Water Pumps

So, I ordered the OEM rebuild kit that Joe found. Thanks Joe! It turns out the parts and even the shape of the impellor are exactly the same as original.





The gasket arrived crusty and broken but I'm not super concerned about that. What IS concerning, is the company that Tim found to overhaul water pumps is MIA. I was in contact with them for a week about doing the rebuild and I was ready to send them the parts. Litterally overnight, their website wend down, phone is off the hook, and no replies on their facebook page.

I'm trying to resist the urge to rebuild this thing myself. I have access to a full machine shop and 20 ton press. Has anyone ever attempted doing this?

I'm also overhauling the Jabsco raw water pump. As you can see, the shielded bearings were seized. They are Hoover 77203-625 bearings. Not made anymore. However, for anyone trying to service one of these bad boys, just call your local bearing joint and tell them you need a 5/8" ID, 40mm OD, and 12mm wide shielded bearing.

Everything was just press fit and held in place with a retaining ring.

Jabsco huh? My 70-71 Chrysler’s have sherwoods. Single or dual pocket?

Ii have done a lot of searching and I believe it's a 17200-0000.

I had wondered about this project thought it had been parted out.....

When i left the boat last fall, I was in the middle of making new primary stringers from scratch. There were a few reasons for this, but mostly because i was adding an engine cradle and going with the "floating floor". I decided that it was smart to do a test fit of the old block and trans on the new stringers to verify alignment before permanently gluing the stringers in place. Here are a few pics of the setup. I just wanted to make sure it was close. The engine mounts on the trans were cocked a little which is why there looks to be lateral misalignment. It was a horrible process trying to wrestle the block in place by myself while being mindful to not step on the thin floor areas.

Now for a few questions.

1. Does anyone have an extra forward engine mount.......loop.........pin.......thingy. Mine has gone missing between the machine shop, disassembly, and moving parts.




2. Can someone measure the distance from the floor to the bottom of the dash? mine seems very tight right now. Especially since i don't have cushion on the seat yet.

Frankenotter—that’ll fit in the jump seat, no problem
