Fuel supply issue

[cyoungmm331]

Hope all is well. So I picked up an 09 210 back in the fall. During the break in period, I started having severe surging issues (not related to the known ZO problem) and it turned out to be the low pressure fuel pump was losing pressure and starving the high pressure pump...basically, the boat was running out of gas. So the dealer fixed it and it ran fine a couple of different times for an hour or so.

Fast forward to Tuesday and I went riding for the first time this season with some buddies. While we were riding for a couple hours, the boat ran fine. 15 minutes into surfing (with the port side loaded up with ballast), the surging started again. I've taken the boat into the dealer and they are going to check it out next week. Anyone have any thoughts on what it could be? Didn't seem nearly as severe as the low pressure fuel pump issue. Could it be bad gas, sediment in the tank, condensation in the tank? Any feedback as to other known issues would be much appreciated.

Thanks.

How Full was the tank

If your tank was under 1/3 full when you surf the boat it is usually tilted quite a bit. With any king of porpoising the gas may be sloshing around so much that your gas pickup is pulling air.
