Dealer Flushing Adapter for a Mercury SportJet?

[jetty22]

I have a 1993 Bayliner Jazz with a Mercury SportJet 90. It can be flushed at the top of the cylinder head or through the engine cooling hose. Apparently, you can only run the engine when you flush it by the cooling hose but.. I need an adapter for it. Does anyone know where to get the adapter for the engine cooling hose or the dimensions for it?

Flushing Cooling System
Flushing the cooling system is essential after each use in salt water, after the boat has run
aground, or when the overheat warning horn sounds (debris in jet powerhead). We recommend
using Dealer Kit (P/N 22-820573) to flush the cooling system.
1. Disconnect the inlet water hose at the rear starboard corner of the pump housing. Install
the Dealer Kit and attach water hose.
