2GM20 raw water engine flush

[UK-WOOZY]

I use a T valve at the water intake to flush the engine after each saltwater use. For descaling I run the engine to operational temp. Flick the valve to draw the de-scaler solution. Stop the engine let the chem do its magic. A couple of cycles and all good. No need to fidle around with the thermostat which also gets cleaned with my method. Once done replace the anodes or replace them with blanks before starting.

got any photos of the setup please

Sorry. Boat sold. But simple just a T-Valve with a long hose to the bucket. Then switch between raw water inlet and the hose to the bucket.

You can get specific valves and adaptors like these from Groco, but easy enough to create something with an ordinary 3 way valve.
