Does anyone else have a Speedseal Impeller cover? I’m looking for the size of the O-Ring to order new ones. The company is now out of business, and the measurements are not an exact match to what I’ve found.
TIA -

I have one for my Westerbeke 21 pump , part number 48080
1mm, and the ID of the O ring either 40mm or 60mm depending on the cover plate size

Thanks - On my Westerbeke 27A, mine measures 52mm ID and 54.5mm OD. I think 1mm is correct. Ordered and I’ll let you know if it fits -

Just to follow up, I purchased 3 sizes of o-rings from Grainger and McMaster Carr to see which ones matched the original and fit correctly. The ones from McMaster Carr, sized at 1.5mm x 52mm fit perfectly. Assuming I change them once a year each time I replace the impeller, I now have 24 more years of o-rings.

Good information update. I installed a Speed Seal cover back around 2006. Also had to change out the water pump to one that fit the cover. Look like it would make changing the water impeller much easier. Never got to try it as I converted to Electric Propulsion before the impeller needed changing. Still it looked like a great solution to the impeller change out on some Nonsuch engines. Too bad they are no longer made.
Bob what engine and pump model do you have ?
I have the 27A motor and I believe it is a 24143 pump.
Is that the original with the evil half moon key and cir clip? I got so fed up trying to change that impeller on my w21 that I changed it for the new version…48080. it uses a pin and is easier to install.
No so bad I guess if you have a V drive, but hell on wheels with a regular shaft
My impeller just pops off the shaft out of the enclosure, and the shaft has a pin crosswise that catches the impeller. It’s not like the one in my Westerbeke manual and must have been changed by the PO.
Same as mine the 40800 model. I get my impellers from Sherwood and the only diff is the pin size is abit too big so I punch it out and replace it with the Westerbeke one.
