"I have a Volvo AD41 B later model series and we have been having some trouble with the engine not having power while trying to go back onto the trailer after either a 4 hours water test or a full day of trolling. We have since changed the lift pump, checked and cleared the return line. Tried testing while running the fuel source directly from a separate canister and returning into the same (did not however check for the air in the loop). The boat would run fine all day while fishing and when we return home while throttling down to enter the marina there would be no response with the throttle. Only idle forward if anything. After letting the boat rest for a day then the engine would run fine. We also just changed both fuel tanks and changed all fuel lines including the vents. Any thoughts of what we can try next?"
