two of the last three times i've been out, i'll be running down the lake and motor just seems like it losses all fuel. it slows down but never shuts down. could this possibly be a VST filter issue or any other ideas? both times this happened the motor ran fine for the rest of the day. kinda acts like an old boat i used to have that would a fuel venting issue but being it goes back to working without doing anything i'm not sure.
Having same problem! Mine does it after the heat and humidity of the day gets up! Runs fine in the morning then starts vapor locking in the late morning! Taking mine in and having them change the VST filters and I think there is a valve(VSV) that can cause this problem!
let me know your results. seems like it doenst happen enough that if I took it in to get worked on, they would just be throwing parts at it. changing the filters would be only things right now. not familiar with the VSV valve, will do some research. do you know if there are any other vent lines that may need to checking besides the main tank vent?
thanks
Not sure myself of all the different things it could be that’s happening. Neither do any of the mechanics that I’ve spoke with around here in central Florida! So I’m starting from under the cowling and will work my way back to the gas tanks. Parts are on order so I will post results when I can.
My 2016 250 SHO would sporadically bog down and eventually die completely. The fuel primer bulb would be soft. changing VST filters solved the problem.
i'll check for this if it happens again.

any good Youtube videos to recommend for doing this job? thanks

filters, seals, and gaskets on the way.
For those who have done this, did you replace the intake runner o-ring gasket? Or did you find the original to be in good enough shape to reuse? That oring is quite pricey.
reuse the original unless there are kinks or tears. I’ve had my intake runners off at least a dozen times on the same gaskets with zero issues. Same for valve covers.

Big thanks! Good to know.
those seals and gaskets are where they get you. probably dont cost five dollars to make any of them. but we all know what BOAT means!
