If your rpms are high and your losing thrust you spun a rubber hub like Bob said or your motor is trimmed to high and you are grabbing air on your prop. I saw your other post about your trim. Maybe you are trying to keep it trimmed up to far ?
I have been using Daiwa Wilderness Trolling Rods in Med action from Fishusa for my board rods last few years.Hard to beat for $16 each. They even come with a hook keeper.They are currently back ordered but should be back in stock soon.
If you have a live well that takes in water from a pump check the lines and have a spare plug in case they become compromised.Sometimes they hold water after draining your boat in the fall and freeze over the winter and split. Found that one out the hard way a few years ago opening night of Walleye.10 minutes into fishing my deck was covered in water. If I didn't have a spare plug boat would have sank.
