Paper gaskets necessary?

Short-term emergency... sure. But by definition its waterproof so leakage is possible if things aren't tightened just so.

I agree with a previous comment about using old nautical paper charts. Because anyway, by the time we get back to some of those places in the world (if ever) we'll need a new set of charts so no big deal.

It doesn't take many $20 gaskets to justify the cost of a Speedseal!

It takes only one attempt to change an impeller on a water pump">raw water pump that has its cover turned away from the access panel and reachable only through a gap between the lift pump and the heat exchanger to justify the cost of a speedseal.

Yes, but.... Buy 2 or 3 of those skinny "O" rings when you buy the speedseal, because in out of the way places, it's hard to find them so small in diameter!

I would imagine RTV silicone might work, but if you're not careful or apply too much some sealant runs the risk of getting inside and clogging the heat exchanger, right?

My pump is a Sherwood 10077 on a Westerbeke 58.

Thoughts appreciated.

Where the heck are you finding $20 paper gaskets?

I’m pretty sure 10077 is the impeller number not the pump number. It usually sells for about $25 and includes a gasket. If you just need the gasket it’s probably #10286 and should sell for $3 or $4.

This is true and if it falls it will fall in the bilge, which is dark and deep and frightening.

I dunno... we are IN Eden and I see no bloody flaming sword, ahead or astern. Maybe you saw one of the oil rigs burning off!

I do believe Ann is currently in Eden, is she the angel you refer to

Look onboard, rather than over the rails...

It has always amused me... Eden sounds paradisaical, but it is located between Wreck bay and Disaster Bay... go figger!

(Actually it is a nice town, and there are safe anchorages for most conditions, but none for all conditions. This means doing the Twofold bay shuffle as fronts come through!)

I should clarify - I’ve been buying them in the kits (impeller and gasket) for about $25. I recently found the impellers alone cheaper in multi packs, but haven’t been able to find the gaskets alone. Having the part number solved it - Sherwood 10286 brought it right up $2.80 ea. However, now that I know I can make them from magazines I’ll probably just do that.

Only a sailor would spend fifteen minutes making a paper gasket that won’t be as good as the original to save $2.80!

Seriously, the thickness of the gasket is important as it sets the clearance between the side of the impeller and the face plate.
