Just bought a 16' open bow with a 1975 Evinrude 115 HP. Motor appears to need some work (starter, water pump, ???) and in the meantime I found a Mercury 65 HP in good shape that I can buy at a decent price. Would the Mercury be adequate to pull a skier on a 16 footer (and money better spent) or am I better putting my money into repairing the Evinrude 115? Any opinion welcomed! Thanks in advance!
