12V Macerator pump

[ianc1200]

Anybody got recommendations about a 12V macerator/pump with a 38mm outlet? All the one's I can find are 25mm outlet. I'm re-plumbing the holding tanks in, unused by previous owner for some 18 years. So toilet to divertor valve, then to holding tank, then along with standard pump out a Y valve to a macerator/pump, then to the 38mm pipe from the divertor valve to the seacock. Could of course simply use an adapter to get back to 38mm, but if there was a macerator/pump with a 38mm outlet would be a bit simpler.

It is common to pump out to a dedicated 25mm outlet from the tank rather than back to the main outlet. Pretty sure moat macerator pumps are 25mm. ,Plumbing is 38mm from toilet to Y valve to seacock and tank. Shoreside pumpout and 25mm outlet with pump to dedicated seacock.

Thanks. I'm guessing there's not too many boats who want to pump out from holding tank to seacock so I might struggle to get one.
