Help!! I have a 15ft whaler sport circa 1985 with a 70 hp 3 cyl two stroke yamaha outboard(86 I think), that will not crank. The boat ran great all last summer but when I went to winterise with fuel additive it cranked a few times then quit cranking all together. The battery has 12.6 v all gauges lights and aux power are working, when I turn the key I get nothing not even a click? Any help would be great! Thanks
