Comments. Unofficial. An in-house Sportsman sea trial on the Ashley River (sunny, 52° F, slight chop), not a Yamaha Performance Bulletin. 3 people aboard, 40 gal of fuel, livewells empty. Tested by Jeff Hudson and Stephen Cruz; approved JH, 9 Oct 2026. Boat ran and handled great: holeshot 10 of 10, hard-turn stability great, on plane in 3 s against a 4 s target. Against the Product Development Scope targets (baseline Masters 267): top speed 59.4 mph vs 60, cruise 35.3 mph at 3,500 rpm on 16.8 gph vs 33 mph on 16 gph.
Approximate and provided as a guideline only. Your boat's performance will vary with weight, sea state, wind, temperature, elevation, bottom condition, options and operator. Confirm figures for your specific boat and engine package with your Sportsman dealer before purchase.
