I am looking to buy a 1993 Ranger 361V with a Johnson fast strike 150 ...Previous owner who is 80 years old has owned it since 1994 & cannot fish anymore ...It has sat for over a year & has hardly a scratch top & bottom with quite the shine . His son said he fished it about 5-8 times a year ..Has a new lower unit & his son who is selling it for him says due to his dementia he cannot tell him anything about routine maintinence ..That is my concern the most . You guys are pro's & i know very little about this year & make of boat & engine .He is asking $7500 ..would appreciate any feedback ...Thank you
