I plan on trailering my 2010 Ranger boat to FL & use in both fresh water & saltwater for 6 weeks. Modern outboard engines & fiberglass / composite boats should do well in both fresh water & saltwater by just rinsing off boat & flushing out engine with fresh water IMO. The Ranger trailer is powder coated, sealed LED lights, surge brakes with sealed oil bath bearings & fiberglass fenders so also should do well for dual use. My boat in summer will see many Northern WI lakes & when not on the move it will be on a boat lift.There seems to be many opinions regarding saltwater damage in general to boats & trailers but seems to me many Ranger Rigs do both well in FL. What is you opinion & why?
