I need some more detailed advice about water injection headers. My 460 BB Ford has a Berkley drive unit. I have a connection for my fresh water garden hose, but I never see any water coming out of the exhaust outlets. This has me worried greatly. I can not seem to find any gate valves on the system. I did find what I call a T-valve, and it makes the hose water go into the engine and then out the dual exhausts. This T-valve when closed keeps the boat from flooding with river water. I can not make the water circulate. I got the engine running great, and I think I never waited long enough for the thermostat to open, and this is the reason for no water being discharged. Temp gau.ge only got up to 150 and I shut it down, as I was afraid I would ruin the engine
Does anyone think perhaps the engine coolant passages are clogged with sand or rust? The engine has only 40 hrs and has custom parts from Dooley Marine and Hardin Marine. Does any of these parts cause the condition I am seeing? Would good advice be, open up the thermostat housing and header water injection lines, I understand unwanted debris could be in there, but nothing appears to be in such a terrible condition..Should I just start tearing it down till I find what is causing my problem,. I have not taken the boat to the water yet, as I wanted to enjoy this nice boat and destroy it.
Where should I plumb the t-valve for my headers, into the discharge line our between the water pump and cyl head?
Discharge side of thermostat housing. One side of t-stat to a ball valve regulated dump out the back (or my/many peeps preference @ driver seat side area of the hull) and the other to the t-valve splitting out to the headers. You can also run a multi-position header water control valve at the drivers seat that allows you to turn the water on/off at any time, idle etc. and then regulate how much water you supply the headers per rpm. ( my/many peeps preference also) Sometimes the spring ball check valve delios in the t-valve can get stuck open or closed and cause you problems. I prefer full control at the seat.
