Quick connect for flushing engine hose?

[rcliff10]

Is there any good reason not to use a quick disconnect on the engine flush port like shown below for easier flush out and less wear any tear on the hose fitting? In this case it's for a 350 4-stroke



Thanks

I use the 1st (left) with no problem.
Just remember... Yamaha just recomends use flushing hose with motor stopped.
For flushing motor running use ears or better both (that block must need lot of water to fill)

Good luck
