Volvo penta 7.4 gi engine flushing

[cruiser262]

Hello everyone,

does anyone know how to flush the volvo penta 7.4 gi?I read that recent Volvo penta engines now have a port where a garden hose or a flushing kit can be connected to clean it with the boat still in the water.Any ideas/suggestions?

cheers

Not unless someone installed that type of flush fitting.

you can add a superflush kit http://www.superflushsystems.com/cms.php?id_cms=14

otherwise you need to block off the lower inlet while introducing a fresh water source. it can be done, however many people forget to turn the valve back the other way and overheat.

Thanks

i had a look thoroughly at the cooling system.It takes sea water from the outdrive.To flush the engine there's a specific port starboard on the aft deck close to the battery switch that allows fresh water to clean the engine.Now my question is does it flush the outdrive as well or only the engine block and exhaust system?
