This Sea Nymph outboard utility has a aluminum hull, is 18 feet long and 78 inches wide at the widest point. The boat weighs approximately 485 pounds with an empty fuel tank and without any gear or passengers. The maximum horsepower we have listed for this outboard boat is 130 hp . If repowering you will want to verify the max horsepower for safety and to make sure your insurance company will insure your boat. New engines are expensive so having the manual for your engine is a great investment.
Despite the aluminum hull on this utility, we recommend that the boat be kept dry and covered in order to preserve the value of the boat. Proper care and regular maintenance can help your craft stay nice and increase resale value. We have included some outboard engine information since a boat isn't much good without a good, reliable source of power.
Information on this page is provided to you as a free service of iboats.com. Because this information has come from many sources we can not guarantee its accuracy. Even if this information is the same as the original factory specs, boats are sometimes modified. Thus, for safety and other reasons, it is a good idea to verify information here to make sure it matches up with your boat. For additional information, we recommend the iboats forums and a boating safety course.
