Suzuki 40 Hp 2 stroke

Suzuki's 40 HP two-stroke is a twin-cylinder engine displacing 696 cc, with a bore and stroke of 79 by 71 mm, weighing 76 kg on a 508 mm shaft and steered remotely rather than by tiller.

Running on a fuel-oil mix

Unlike the four-stroke motors in this lineup, this engine runs on a 50 to 1 fuel-to-oil mixture rather than drawing oil from a separate sump, so keep pre-mixed fuel on hand rather than straight gasoline. Maximum output is rated at 29.4kw, with full throttle running from 5,000 to 5,600rpm.

Rigging details

Electric start is standard, shifting through forward, neutral and reverse at a 2.09 to 1 gear ratio, and an optional 12-volt, 80-watt alternator can be added if your rigging needs more charging capacity than the base engine provides. Propeller pitch is available across a wide range so your rigger can match it to your hull and load.

Who it suits

A two-cylinder two-stroke like this is lighter for its displacement than a comparable four-stroke, which matters on boats where keeping weight off the transom affects handling and fuel burn, and it suits owners already set up to carry pre-mixed fuel.

Does this engine need an oil sump? No, it runs on a 50 to 1 fuel-oil mix instead. Is the alternator included? It is listed as optional on this motor.
