I've read on many forums that salt water usage is something I should take into account when making a offer on an outboard. Up to this point I've avoided all motors that have been used in salt water. Nada states this also so I assume it's a real problem. What is the best and most expedient way to inspect a motor to see if it's been maintained correctly? Also, when making offers, how much should a person offer for lower hour usage? I've seen some outboards that for example only have 266 substantiated hours on it, but is a 2006 vintage. Nada stated it's worth on average 2500 roughly. The seller is asking in the 6K range. I understand it has low hours but disparity of 3500 dollars?, really? The manufacturer is no longer in business so parts availablility could also be an issue in the future. This is why I don't make offers on Johnson and Evinrude. Am I being paranoid?
