Position this between the 11800 (5 gal, 735-11800) and the 11841\/11842 (11 gal) when advising customers on capacity — it’s a strong recommendation for two-person cruisers where the 5-gallon runs short on passage but the 11-gallon is overkill. At 9.1 kg it’s a manageable single-person install in most configurations. Same engine coolant-only restriction applies to the heat exchanger — flag for raw-water-cooled engine vessels.
