Cobalt R4 Outboard
The benchmark bowrider, Yamaha-powered.
The R4 is Cobalt's core bowrider — the seating, the upholstery, the helm feel that make Cobalt the benchmark everyone else measures against — and in outboard trim it takes a Yamaha F300 on the back. Sandbar days, tubing, dinner runs across the bay: this is the boat those days were invented for.
The outboard version is why RT 113 carries it: a Cobalt our own Yamaha Pro Elite shop can service completely, mounted on the brand famous for holding its value. Yamaha even published performance numbers for this exact package — linked on our listing. Cobalt joined our lineup in 2023 as the play side of a fleet chosen brand by brand.
