Have any of you 44DB owners created a fuel consumption chart? I have QSC 500's and I'm in the process, logging RPM at 100 RPM intervals, with knots and GPH at each interval. Trying to get multiple readings at each RPM level and then take an average. Slow going, and just wondered if anyone else had similar info you could share.

Does anyone have a good source for o-rings? I'd like to change the o-rings when I do my impellers, and looked at pumpvendor.com and they're charging $16 for the big o-ring where the pump mates with the engine. That seems high. I'd like to stock up on all the common o-rings.
Thanks,
Scott
There is viton, buna-n, silicone, natural rubber, PTFE, EPDM, neoprene, and about ten other materials and differing hardness'. Each has a specific service so unless the exact material is known it would be a crap shoot on a failure. With that said viton and silicone are the most common. O-rings from the typical big box auto parts store are minimal grade neoprene.Are they not just standard O-rings?
Why can't you measure them and pick them up at NAPA or order them from Grainger?

The Sherwood Impellers come with O rings in the package. What impellers are you using?Does anyone have a good source for o-rings?

Thank you. Yes, I've looked at their kits. They have a kit (#1730) with a football gasket, which is not what is originally used on my QSC-500, so I'm not sure it is correct for the pump I have, maybe someone can confirm if it will work as a replacement. I have the original pump which has an o-ring where the pump meets the engine and not a football gasket.Have you tried Seaboard Marine? They have o ring kits available.
