My fresh water pickups are mounted to the transom, does anyone know where I can get the correct adapter to pump the antifreeze through, ive seen tons for alphas and bravos, but these water pickups are like and inch wide by half inch....rectangle...
Or any other recommendations to get it done.
thanks

Pull a hose off before the sea water pump and fill there. Install some flush kits and do it from there.

the Hard way the first time ..then easy after that is put a ball vlave in the line(hose) in side your transom before the water pump (which is a good idea to have anyway)... then a t-fitting up the a conv. place with another ball valve and hose adapter.
Look at the fountain set up to get a reference.

Funnel, hose, and secret ingredient, Duct Tape!
Or pour in the strainers, if you have them.

all great ideas... i do have strainers i guess i could pop the hose off that connect to them and pump from there through the motors....
the in line adapter is probably the way to go for future though... thanks for the ideas
