While having the opportunity to explore the mostly normally hidden nether of the boat while the leaking fuel tanks are pulled, I discovered my aft bilge pump (a PAR diaphragm) isn't pumping. Advised by my yard that it's probably the valves and/or diaphragm - a Jabsco service kit should take care of it.
Recognizing the advantage of the PAR to deal with a net negative suction head (needed the way the pump was located by the boat manufacturer), I'm trying to figure out the next step.
I believe the PAR pump I have is a Jabsco 37202-0000 - rated 270 gph, 7.5 a @ 12v. Replace with new ~ $330. Service kit ~ $100 if rebuildable + labor. Situation probably prevents me from DYI, so some unknown labor additional.
A Rule 3700 plus a float switch is about $220, and I could see installing that myself on a weekend afternoon.
To be clear, I understand the BS capacity rating system used by Rule (and maybe Jabsco), but even discounting Rule's numbers by 60% to account for discharge lift, hose size, voltage droop, etc. - it looks like I can get 5X the flow capacity for considerably less cost.
What am I missing?
Also - what's the deal on Rule's "Gold" series? I know it's touted for "commercial" service, apparently due to its "double insulated long-stack motor". Do I care?
Thank you, as always.
