    Default water lines to header question

    @ the water tubes to the headers there is a -8 fitting to a steal braided hose. One header has a small hole in the fitting such as a restrictor fitting and the other side is just wide open as a normal fitting. So the question is witch one to use. Fyi: I do have a control valve at driver seat to control the water to the headers.

    mine is the same way, but very little water come out anyway (steam actually) one side resrticted and one side open still produce the same amount of steam.

    Default Water Injection

    A good way to do it have a pick up just for the headers. That way you don't get any water until the boat is moving and the motor is above an idle. I also use 2 clear glass fuel filter in lines going to the headers and put a .100" diameter restrictor after the filter just before the start of the water branch. That way you get enough water to cool the header but not so much as to flood the engine. I have been setting systems this way for year and it works really well and there aren't any moving parts to act up. You can look through the glass filters to see if they are getting full of junk so nothing gets clogged.
