The four-stroke MSF25 outboard from Tohatsu Outboards uses cross-flow induction for quick acceleration and response. Conventional electronic fuel-injected outboards get power from the battery through the key switch, but the MSF25 receives its voltage directly from the alternator, which allows it to be started with a pull rope or electric starter instead of a battery, so it starts in all conditions. The 25 comes with a three-year limited warranty. Tohatsu America; (972) 323-6003; www.tohatsu.com Tohatsu MSF25
