I really want to install a side water dump so that at any time i can tell that my motor is getting water. I come from the Jet ski and yamaha jet boat world and they all have water "pee" lines that you can tell that the motors are getting water. When i drop the boat in the water at rmp i allways check under the swim platform buy thats a pain.

Anyone don this?? Where is the best place to tap in to the block, where i won't mess up water pressure and cooling capabilities. my yamaha jet boat had two, being a twin engine, maybe 1/4 or 3/8 line.

Although I plumbed in my intercooler this way (a seprate pickup). Trust your water pressure guage. I've found it hard to keep looking over my shoulder when running 90+mph w/ 1-2 foot chop and dodging other boats on the water. I think that its safer and easier to refer to the guages.

ya mine no race boat!! Its just so i dont have to visualy check when i drop it in the water that is pumping h20. Im not going to put in a pressure gauge, no room on dash and its just a fairly stock outlaw.

The water pressure gage would be easier and most likely cheaper or comparable in cost. Plus you will have the running feedback to know what your pressure is doing. Too high a pressure when running can cause blown head gaskets and such, so there would be more that the one benefit from what greenkeeper suggests.

Better to run a guage that you can see all the time to know your water pressure to properly know how your cooling system is performing. Plus you dont have to drill a hole in the side of the boat.

Ballon78,

I'm feelin ya ,what I ment to say is that a guage reference is the best and safest way to moniter the engine. Whether I'm going slow or fast I am continuisly monitering ALL my guages. Although I'd rather watch my wifes tits bounce your eyes gotta be glued to the insturment panel. I've found that when going into a head wind at high speed I cannot hear the engine only the wind. (I can only imagine what its like to go into the triple digits). The water dump is more for a quick referance and is not giving you all the details. A big block is a big block and when she gets hurt it takes a lot of dust to fix her. Good luck.

Lift the hatch when you start the engine and feel the exhaust risers after 20 seconds. If you don't get blisters, there is water going through.
Seriously, if the temp doesn't go up in a hurry and past 150-160* then its getting water. Also, it will be significantly louder without water mixing in the exhaust.

I wanted to do this also.





tried your method and it worked great.

Dont worry about it, you'll know if it is not getting water very fast. It is also a very rare problem.

You won't be able to see the water comng out very easily anyways when running WO. It'll be blowing back against the side of the boat. So while you are looking backwards trying to decide if that is water out of the motor or just spray, you could have glanced down and got an accurate reading from a gauge and looked back up, and forward.
