I recently purchased a nu boat w/ 1986 70 Johnson VRO it ran fine through 1 1/2 tanks of gas. Took it out a few days later and it had no power at wot. The Boat Doctor i took it too blamed bad gas (Water and Old Oil gunk) either from second tank or station or both ?<br /><br />He cleand the carbs and it ran great through 2 more tanks of gas today.<br /><br />Would a water sperator possibly prevented the origional problem ?<br /><br />Can you find these babies at Walmart ?
