also when buying used make sure to keep clear of boats that have been run in saltwater. Saltwater tends to wear motors and lower units a lot faster then freshwater. If your going to use it in saltwater I guess it really doesn’t matter.
Also note if you want to do any modifications to your boat to careful of which drive you get. The Mercury Alpha drive is only good up to 300 HP or so. If you want to add any power adders I’d suggest getting a boat with the Bravo drive.
sea ray, crown line, and cobalt all have good resale for a boat but overall they still have bad resale value.
