Hi All my engines have what I assume are flushing fitting on the right side of each engine I can't find the male adapter on the boat . how does every one use these fittings. been told to just hook hose to it and turn on the water but I would like to know the right way if possible. thanks
The right way to flush is written in the manual. Below is my version
With a hot engine - switch it off.
Close water inlets (seacock's) - plug the hose into the flush port.
Turn water on - and wait 30 seconds with water running.
Start engine. Run at slightly above idle (I use 900-1000 rpm) for 10-15 minutes.
Switch Engine off.
Wait 10 seconds.
Switch water supply off.
Leave seacocks closed until next outing.
Don't flush a cold engine. The heat opens up the "pores" in the metal - so if you let it cool with salt water in there - the salt might get slightly encased into the engine metal - and that makes rust come faster. So flush while engine is still hot - and so hot that the thermostat opens (so within normal operating temperature)
I have cut my 10-15 minute flush part down to about 3-4 minutes - since I use SaltAway to flush with. So I have a SaltAway dispenser on the hose. So my flush sequence is:
With a hot engine - switch it off.
Close water inlets (seacock's) - plug the hose into the flush port.
Turn water on - and wait 30 seconds with water running.
Start engine. Run at slightly above idle (I use 900-1000 rpm) for 2 minutes with SaltAway in RINSE MODE (only water comes through)
Continue at same RPM - but move SaltAway to SaltAway mode (so SaltAway is mixed with the water) until I see "soapy" bubbles from exhaust. (about 60 seconds)
Switch Engine off.
Wait 10 seconds.
Switch water supply off.
Leave seacocks closed until next outing.
At my last inspection the risers looked like new inside. And I am in the absolute worst place for growth with some of the saltiest water in the world.
