Have a 87 242g Offshore with a 05 F250 yamaha full transom on a bracket that runs great. We have been venturing 20-30 miles offshore more frequently and have been thinking of selling the single and installing 2 F115 yamaha for more peace of mind. Any thoughts on weight, 605lbs for the single and 424lbs a piece so 848lbs for the pair. Also, 93gallon tank enough? In research it appears certain models came with two motors so im thinking it would be ok. Any thoughts.....
