I have a 2001 bahacruiser 286 sportfish w/ a 8.1 liter Volvo penta I/0 (400 hp I think). I've bought the largest beefy bags Amish outfitters sells (one on each side obviously). Had the maps sensor replaced/fixed and still having trouble getting below 2mph when trolling. Any ideas on how to get her slower besides shelling out the pesos for a kicker motor?
