2000 gtx rfi rev limiter?

Hey guys just wondering if anyone could tell me if the gtx rfi has a rev limiter, and if so what does it limit at?

I believe my limiter is at 7200
Couple years older, 98

Is this a safety feature? Guess i dont pay enough attention but i think WOT on mine is in the ballpark of 6500?

Rev limiter cuts out the ignition if you hit that rpm. When the rpm drops below the limiter threshold the ignition comes back on. It would feel like the engine is cutting out briefly. If that's not what you are feeling, I think what your experiencing is just the limit of your engine power in the water..
Mine runs around 6800 unless I hit a wave or something and I see rpms jump a little.

Yes, a rev limiter is to keep you from spinning the mlm motor too fast and killing it

So i cut a really hard line in the water and it ended up spinning me around completely and then to a stop. I think the nose dived cause i got soaked but did not go under or fall off. I wasnt punched WOT by a long shot but must have cavitated or something cause my rpms did shoot up more than expected, like jumping a wave. I do not believe i hit the rev limiter nor was i even close but did rev it up higher than i would have liked to.

I ride with my wife 99% of the time so i am usually driving the thing like a 22’ boat but i was alone tonight and the water was like glass.

Just wondering about the rev limiter cause i dont wanna blow it up. I rev up some times when hitting waves as well although i let off immediately. Also resulting in losing all momentum. Usually when the water is really choppy. I know this isnt good for the machine but must be able to handle some of this behavior to a degree?

When you spun around and the nose dove you most likely got some air or a bit of cavitation. Mine has done it.. I like 360... when I do, I let off about half way, as it stops spinning it rock backwards on my feet off the seat a tad then gun it. Weight to the rear helps stick the back down and pop the front up and pull out of the water. The rev limiter wont allow you to over spin. I use to jump waves and wakes with my yamaha clear out of the water. I never let off the throttle in the air.

 

[rob04064]

So is it bad to hold the throttle when jumping waves or no?

It's bad to hold it wide open any time the pump is out of the water if you can help it. Once the pump is back in the water there is a quick load on the engine, just like you wouldn't hold a motorcycle wide open and just let it hit the ground in the air.

 

[rob04064]

Yes i figured that and i always let off, but sometimes not till i am in the air so there is a moment of zero load on the motor, and a spike in rpms, always letting off before setting back in the water. This is usually when there is a lot of chop in the water so i am not operating at WOT anyway. I see other people on the lake going at it hard all day long. Cant imagine they get a lot of longevity out of their machine...?

The scenario i drew out in post #6 was like a once-and-only. I am usually never that hard on equipment of any kind. Just wanted to know if once in awhile is ok or if i need to avoid it like the plague because a lot of the time the water can get pretty rough on the weekends.

7200 rpm +/- 50
