What vent plugs,if any at all are u running. I have a 2000 520 dvx with mercury 225 optimax with 25p tempest plus. Looks like small plugs in right now. Last night first full tournament load with both tanks full livewells full and me 220 and fishing buddy 270 with about 100 pounds of extra tackle and beverages. Pretty slow out of the hole i would say a good 6 to 7 seconds to get on plane. Also chasing a rough idle in engine so just trying to get a feel what this boat should do as it is a new boat to me.
