And just how pray tel would you do this ?
I would imagine one reason they don't install a valve on the inlet is for liability issues. Do you realize how many people would forget to open the valve and fry the engine, then go after the manufactures for putting it there ? The other reason would be accessibility. It would have to be in a location that you can get to it. These things are crammed full enough as is.
The deal is they knew about it, they have informed us about it, and given recommendations on what not to do. If you insist on not following their recommendations, the consequences will be of your own doing.
agree with you to this extent - I forget ONCE to correctly position the shut-off valve I installed in line with my Wave Runner EX's cooling system, and good-bye motor!
All the more reason why the cooling system SHOULD have been designed to reflect how so many of us use our PWC's.
You telling me it is not possible to come up with a cooling system's plumbing as reliable as my old SeaDoo GTX? Horse feathers!
Is there some reason why all three mfgs. HAD to design their respective cooling systems to insure destruction from towing behind a larger boat - heck, even house-boats can go faster than the limits the jet ski mfgs. have put on. (again, in small print - I know..I know "when all else fails...read the instructions"....!
How come a lowly back-yard wrench turner like me can come up with a solution that requires NO action by the consumer? Dosnt say much for the pwc people...or does it suggest they are a bunch of deliberate crooks?
Simple solution - soon as I can find out where on my PWC's motor I can tap into its vacuum. For many many years, the automotive industry parts suppliers have produced reliable vacuum powered shut-off valves for our car's heating systems. Again, RELIABLE durable, off-the-shelf product..about thirty bucks. Install one of those. Engine starts....motor vacuum opens the cooling valve. Engine stops, vacuum fails, cooling water is shut off.
Which leads us back to the question...what are the mfgs. trying to pull off on consumers? We supposed to believe they have no clue how many of us use the product?
