Wow, a million thanks,now I see why I should of waited another 3 hours,would spare me from cutting the tail section open,but,better late then never,discovered that the shaft seal got old and hard and was letting some water in,probably the cause of motor problem,one of the motor mounting screws was corroded, going to order replacement from Engel. Mean while I'm still hunting for the radio,the receiver in the sub. is:quantum 6ch. futaba stile, 75mhz. Some one offered me futaba am on 75mhz, is it ok? or I should stick to FM? Thanks again for your help Taxidriver.
