2002 seadoo gtx 4tec minor? issue.

[D3v]

As the title says i have an 02 4tec. basically when on the water around 4900 rpm's, the engine likes to waver? the rpm's like to jump up and down by 500 rpm or so. What could cause this?

for a Different subject, family is looking into a 08 gti 130. Whats the over all impression on this seadoo?

thanks for the info/help.

change your plugs, sounds like one is starting to go, quite common at mid rpms. it will go from a waver to surging.
