I dont think you have to be quest registered, but one or the other should be the registered owner of the boat and should be able to prove should it be necessary. Technically if the boat is 2000 model year or newer and warranty not transferred, then there is no warranty. Spend the $150 and transfer warranty and get in quest at same time.
