its a cheap design and is very simple its an anti siphon . with out the hole the hoses could after ejecting water ,the line could still be full of water , and the water could reverse flow .. say you pull up to the dock to stay awhile and right before the bidge was finished ejecting all the water , in the middle of that process you turn the engine off an now no bidge and the water flow reverses an then it starts filling up the craft. lol you come back in two hours an ski is sunk . the little hole breaks the flow. the price to pay is only if in reverse the pressure pushes water up the hose and squirts out the little hole . and it only happens when applying higher rpm when in reverse (because the pressure gets higher along with the higher rpm . . i know my 2018 gti se does it i video taped it . i wanted to know why so much salt in hull. 2018 gti the strainer also has a check valve other wise it would be gallons of water in reverse under throttle. so sea doo engineering did this way. i may not have ever noticed but water hose are in plan view on my 2018... my 96 97 gti the hoses are way in the stern way up in a dark corner nobody ever looks at ill bet the older ones do it but being reverse is a pain in the ass lifting the handle and with the rusty cable its a bit hard , i and most people try not to be bothered putting it in reverse. but with all the seaweed i drive ski in reverse for a long time until i get out of canal otherwise i wouldnt have so much salt . plus my carbon seal issue so i really had to get in there an figure out were the water is coming from.
being the old skis dont have a check valve in the black plastic strainer you may not get water out of elbow but ill bet the older ones do!!! only if in reverse and raising rpm .and you have to really go out your way to look at it big time .for one the seat has to be off and youd have to stick your head in there with a flash light and maybee even a mirror to see it...remember in reverse with higher rpm only way really is on a trailer on some skis my hoses are right in your face on the 2018..so its easier to see if your looking for it !!!!! my picture shows it !! the after math salt everywhere no good imagine cleaning the salt off every time out would take hours , my coolent pump is corroding already the paint is bubbling off .BRP said ooooh .
if i was brp i would have little hoses ejecting water overboard . and either way im going to do it on my own.or something else check valve maybee or at least control the continues squirting so it is aimed on the floor or something but ill fix it.
if you have a later model test it on trailer in water in reverse raise rpm and watch the little tiny holes leave a mess !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
im going to check my 96 97 gtis also to see what happens.
the joke and sad sad thing about this is i have a lousy dealership to say the least the ski was brought in they left it for 3 weeks it was left out in front with key in etc etc etc no work done at all. i got new scratches etc etc they probably let people play on it yea start it up the key in . rev it up have fun put the family on it . etc etc i still have a carbon seal leaking and the dealer said bring it to canada let them look at it. i even have a video the dealer and brp dont care DONT EVEN WANT TO SEE IT !!! i know carbon seal is gray area i just bought ski new left over and after running it 1 hr i call dealer said a lot of salt he said carbon seals are dry seals they dont leak. so what to do etc etc etc blah blah but in the process this is how i discovered the reverse system also has a water issue. at least i can fix myself. warranty . i hope is good for more then toilet paper ,if something like engine failure etc but im afraid id get a story as to how its my fault . ANOTHER EXPERIMENT CALL BRP ASK SOME QUESTIONS LOL.THEY ARE TRAINED TO BE KNOW NOTHING PASS THE BUCK .. you would think if you call brp that they will be happy to help you with tech questions good luck. they dont and wont !!!!!they will tell you to call the dealer and i even left a complaint about dealer all i got was a headache a run around and the conversation was very upsetting to say the least. i though the dealership was bad call brp. it will make me buy a yamaha next ! its very hard to get good tech info on the skis lucky im a mechanic for many years .
i post this to let other know my findings if theres a good dealer in jersey or connecticut let me know ill have to drive hours if i find someone who isnt a wiseguy.and a good person really looking to help you have a good day even when your not on the water and looking for a repair or info. thanks much .
