is one piece episode 148 filler?

Usopp tries repairing the damages from the sonar attack but the crew keeps talking about replacing the ship. Usopp gets mad, asking them if they remember how they got the ship in the first place.

Luffy tells Usopp not to complain and that the ship is part of the crew and that it needs to be fixed. That was before he hit a hole in the ship, making Usopp angry again.

Nami looks at the map explaining that they are headed east by circling the island on their way to visit Mont Blanc Cricket. Luffy and Usopp are shocked to see a huge carnival palace looking house.
