I'm looking for a carolina skiff right now (used) and have come across a J16 with a 2000 nissan 25 2stroke e-start remote. My concern is...the boat has been USED. The owner is a regular on a fishing forum I frequent and keeps the boat hanging (out of water) and fishes it frequently. He says the water pump impeller has never been changed (lower unit has never been off). The motor was bought new in '02 so that's 4 years of salt use. Assuming it was flushed regularly, is there anything I need to look at other than the general appearance/performance of the motor?
