My apologies to Dave & Rad for not being more clear.
My question was about the "small print" in the back of the manual for my brand new EX Sport. Where they warn you that it cannot be towed at more than 5 mph. (Didn't see that in page after page of operator info. in the front of the manual) Didn't see that in page after page of advertising I reviewed before buying it - material both at the dealer's show-room, and on the Internet.
I cant imagine anything more stupid or potentially damaging to the consumer, than designing something that cannot be towed at more than 5 mph. But that's the way this one ismade.
Not clear where Rod got the idea "all pwc's are set up this way" - guess he never heard of Seadoo - I own one - been towing pwc's behind our cabin cruiser for some thirty years now. As a side-note, the Sea Doo that is in direct competition to the EX has a "closed cooling system" so you could tow it a hundred mph and would have no effect on the cooling system. My older SeaDoo GTX is doing fine after many years of towing.
Anyway, I failed to explain I was not asking about cutting a couple of big holes thru the side of my EX to re-route the water cooling hoses outside. Of course that is absurd - sorry I gave that impression. What I was asking about if anyone knows of a water shut-off valve in which the handle could be outside the hull - of course the valve body itself and the hose would remain where it belongs, inside the hull. My local hardware store has all manner of "ball type" shut off valves for a couple of dollars, just like the Wave Eater I paid twenty bucks for. But like the Wave Eater there is no way to get the handle off the valve body for exterior mounting of the handle.
Surely someone has come up with a way to stop this idiocy with a simple ball valve like the Wave Eater - - I would not have bought a Yamaha product if this nonsense had been disclosed on their advertising.
Yes, I "get it" - for now...every time we tow our EX to a nice beach, I've got to lift off the seat, pull off the storage box, reach down into the hull to operate the Wave Eater. C'mon guys....some ideas, please ?
