      If there's a reduction in water flow from the bilge pump, clean the screen at the base of the pump. Also, check the discharge hose and clean or repair it as needed. Reroute the hose so it runs uphill from the pump to the thru-hull fitting, and check the battery and wire connections.

    Why is my Monterey Boats Boat sluggish and losing speed & RPM?

      Adrian GilbertAug 21, 2025
      Your boat might be sluggish due to several reasons. Start by cleaning the hull and running gear. Ensure the propeller is clean. Reduce the load on the boat. Also, pump out the bilge, identify, and correct the underlying issue. If these steps don't resolve the problem, have a qualified marine technician check the throttle control system.
