They have the same diameter pipe for both inlet and outlet which is different to both the Jabsco sizes, that means either a step up/down or new tail fittings on the through hull fittings.
Fitted two of them. Noisy, but they cope very well with solids, and macerate them into fish sized bites! They cope with loo paper, but nothing else. In particular they will jam with cotton wool, so you need to give a warning to the ladies: you block it, you fix it.
