Marek, You are totally right about possible flooding and not to use PVC. The tee and hose make a great solution for many problems. This rig was used by the engine speacialist who test ran my engine for me prior to purchase. It has worked well for me for ten years.
Didn't want to get too technical but FWIW, My boat has a Marelon Thruhull. Chose a bronze threaded tee, bronze plug , Marelon barb fittings. And I am very careful to throttle the water with the SS ball valve. I also coat the pump impellor with vaseline, because I start the engine from the cockpit and then step into the cabin and crack open the ball valve to lube the impellor and cool the engine. The Universal takes a good long while to come up to temperature, so I don't worry about it overheating for the 30 seconds it takes me to run down the steps. I close the valve after shutting off the engine. I could improve on the rig by lengthening the hose enough to position the valve in the cockpit, where I could also monitor the exhaust. Probably easier to add a short length of garden hose with plastic shutoff, coiled in the cockpit. Maybe some day I'll try that?

If your water pump does not stop the water flow (and it does not have to), you can easily overflow the muffler and the mixing elbow and fill the cylinder(s) with water through the exhaust valves. It does not have to happen (especially, if you are quick with closing the water tap after you stop the engine), but it can happen. If you want to be really paranoid about it, another issue is that the tee is either plastic (PVC) or brass; neither is recommended for under water fittings (PVC β not strong enough; brass β corrosion). just a though Marek (in Ottawa) _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com
