I've got a Yamaha Z250TURB HPDI 2 Strk. I tried to run it on the hose connection that is connected to the engine (not using the ear muffs) and it took the water fine but there did seem to be a lot of steam. I then tried to hook up my antifreeze bucket to the hose connection and it wouldn't take the antifreeze.
My two questions are, is it important to run this engine on antifreeze or does it self drain and will running it on this hose connection and not the ear muffs hurt the impeller in the drive?
