A Jabsco marine toilet pump on the Westerly Yachts Ltd. Oceanquest 35 Zephyr IV fails to draw in flush water — it expels waste but the inlet stroke stops working, pointing to a failed seal.0:12 Dave, 82 years old, replaces the complete pump assembly rather than a £50 service kit, buying a new unit for £85 from a chandlery.0:25 Before disconnecting anything, he flushes the bowl with fresh water, then closes both the inlet and outlet seacocks.1:41 He removes three pipe connections — one with a jubilee clip, one threaded fitting, and one bolted outlet section where he swaps only the gasket rather than fighting the hose off.2:40 All mounting screws are retained for reuse.3:58 A critical step catches him out: the macerator blade must be twisted and withdrawn before the new pump body will seat on the base.6:41 He transfers the outlet flap valve from the old pump to the new one, reassembles in reverse order, reopens the seacocks, and confirms no leaks.7:35 The complete job requires only a large flathead screwdriver and pliers.1:05 Buying a full replacement pump rather than a service kit simplifies the repair when the fault is uncertain and the price difference is small.
