  Duane,   After all the work and time you put into making it, glad to hear. Did you have a hard coat threatment done to it to prevent wear of the softer aluminum? 

No coating yet.  Wanted to make sure it would pump before  $$  Anodizing.  Not planning on brackish or salt water either.  6060-T6 was the material used.  Probably last many many hours under normal usage in fresh water.  If I had KENO'S energy then I would tear it apart and Anodize it.  Too many irons in the fire now.  (maybe need bigger fire?)LOL
Keep it as original as YOU want it

Coatings for the alum pump.....might be a great place to try put PTFE. If the impeller runs dry it might last a few minutes longer.

William—we all wait to hear how it runs once the impeller is in. Is this the third year of this story?

Yes, Duane could send it over to China and have them coat it with the as seen on TV Ninja non stick! Big smile

Yes indeed it's year 3 ! My neighbor asked the other day if I was going to sell it after I get it running. My first thought was, "Are you ***************g kidding?!?"  But I politely replied, 'No, I'm keeping it for myself.". Although I'm not finished, I have no regrets. It's had it's highs and lows. I know I go about things in my own way (read- what the hell am I doing?), but I haven't given up.

As I'm sitting here in the city with my raw water pump in hand, I'm thinking the sound I was hearing, the whining, is probably  the sound of bearings going bad. I wiggled the shaft, a favorite pass time of mine, and it moves side to side a bit. Should it move? Is there an option for a bolt on replacement since this style is obsolete?

In the link below is a Sherwood catalog/manual with lots of info.

page 18 and 19 give info on Sherwood part numbers for your pump. It's a little awkward to read, but if page 18 is right next to page 19 instead of one above the other then things makes sense and you'll see that the great majority of parts are the same as a G21 that's still available.

They give a Sherwood part number for a "major repair kit" for your pump. It's 23977 and has all the internal parts except the shaft.

It's kinda pricey but it's available thru many outfits

A rebuild isn't the easiest thing, you need a press for the bearings and you need to make sure all the snap rings are out so you don't break the housing when trying to get the bearings out You end up replacing the mechanical seal also when doing the bearings.

There are instructions in the catalog/manual in the link and there's a thread by GaryS about his pump rebuild. There's alittle finesse involved with the bearings and mechanical seal.

If you're not comfortable doing it, places like PumpVendor.com and others can do it for you or you could probably get it done locally but ya gotta pay attention to those snap rings


You could also buy the bearings and mechanical seal separately and reuse some of your internal parts but the Sherwood kit is complete..

The bearing is a 62022RS-10 It's 5/8 ID, 35mm OD and 11 mm wide. The 10 on the end is important because that's telling you it has a 5/8 ID.

A 62022RS without the 10 on the end won't work because it has a 15 mm ID which won't work. (it's close but you could never wiggle your shaft into it Wink)

If it'd just the bearing that's bad (besides the impeller), then for $7, get a new bearing.

You might even want to spend 14 bucks for 2 bearings  and then a mechanical seal to go with the bearings like mentioned above Wink

Yes, two bearings are needed. If you do want the seal, industry standards are about 1/3rd the cost of the Sherwood "12859" The industrial standard number should be stamped on the seal.

Bill

There's a number 8 on the Sherwood seal, making me think it's a Type 8 mechanical seal.

Pete will take over from here with the mission of finding you the correct seal for 1/3 the cost of the original equipment  Sherwood, including shipping of course Wink

Thanks guys. I'm thinking I'd need special tools to remove and replace the bearings.(elaboration anyone?) I've contacted the PumpVender people and they charge a flat $90 plus parts. They sent a part list with prices, and they look about the same as the Sherwood retail prices. Leaning that way. Scary that if this raw water pump were not serviceable my entire boat would be obsolete since there's no replacement.

The most special tool is the press, then some snap ring pliers.

Probably a good move to "keep leaning that way" without a press.

It'll be done right, should last a long long time and you won't be wondering if you screwed anything up along the way.

In desperate times, there's always a way to make another pump work if necessary Wink

I mounted a g21 pump in place of the original on my commander.  It was actually very easy with a slight bracket modification.  No worries on the old girl becoming obsolete.  Big smile
