if i use an electric pump to pump anti freeze through transom flush cause damage?


Recommended Posts

i have the rear transom flush on the boat that i use to hook up a hose and flush engine.

this thing wont suck anti freeze through it unless it has pressure..

thought of useing tsunami pump in a bucket with anti freeze and having it pump it in transom flush socket and running it till anti freeze runs out of exhaust then turning off and storing...

can the pump pressure damage anything??

I do something similar with the fake-a-lake for the engine, and the ballast tanks.

I just use a cheap sump pump in a bucket full of anti freeze. The pump puts out a lot of pressure, and will squirt anti freeze all over the place around the edge of the fake-a-lake, so you need to control the flow somehow. A simple garden hose ball valve will do the trick. Kick the pump on with the valve closed, then crack the valve open slowly to start the flow. Works great.

If it doesnt suck the AF like you said...goose the throttle up just a little, it"ll start to grab antifreeze, then you can go back to idle....

Also, ensure your flush seacock is open.

how long is your hose length? is should be a cutoff garden hose, only 2-3ft long
