Need help 1995 Sea-Doo spi

[ksmez]

Hi all I own 1995 Sea-Doo SPI runs fine but for some reason has been giving me in trouble recently attached is a video but for some reason every time I press the throttle it sounds like there is a sucking sound or a bog of some sounding not sure what it is but then right after I give it some more fuel it seems to rev up like fine was hoping anybody could help me out figure out what's causing itVID20250520125914.mp4

Sounds very much like a lean bog to me. How long have you got that machine?
