I have been fishing mid-tx coast for 15 years out of a 2002 Maverick HPX-T. Pleased with boat but the 2002 Yamaha 2 stroke needs new power head. Options are new/ rebuild on head or buy a newer hpx s or hells bay waterman or professional. New 70f. Any ideas on value of boat and trailer in average condition of hpxt? Ideas on stability of the hells Pro vs hpxs?
