We had a chance to test the Formula 260 BR last year, so we were looking forward to wrapping our hands around the throttle of the 240 BR. We had three people aboard our test boat and a half tank of fuel (about 30 gallons or 188 pounds). For power we had a 320 hp MX 6.2 MPI Horizon MerCruiser with a Bravo III drive spinning a 24-inch cupped three-blade stainless steel prop set.
Acceleration was respectable with 7.5 seconds to plane and a 0- to 30-mph time of 9.9 seconds. The 240 BR weighs about 5,000 pounds without fuel, gear or people, so acceleration isn't going to be as snappy as a lightweight sportboat with a big engine.
We posted a top speed of 47.5 mph at 5,000 rpm on our GPS, which would give you a top-speed range of about 104 miles. Sound at top speed was 94 dBa, which is consistent with other runabouts. Our most efficient cruising speed was 30.8 mph at 3,500 rpm, which yielded a cruising range of 154 miles. Sound at cruising speed was 87 dBa, which is in the range we like to see for cruising.
