2019 Evinrude 3.5HP E3RG4

At 41 lbs, the E3RG4 is a compact, single-cylinder 3.5 hp Evinrude meant for small dinghies, inflatables, and backup duty rather than a primary boat motor. It starts by rope and steers from its own tiller handle.

Engine

Final gear is 2.15:1, and the engine tops out between 5000 and 6000 rpm at wide-open throttle, drawing 5.2 cubic inches (86 cc) of displacement from a bore of 2.17 in and a stroke of 1.42 in.

What to check before buying

This motor comes on a 15-inch shaft, so it's suited to small boats and short transoms rather than larger craft; trim adjustment is manual, with no power tilt motor to account for. The small tank runs on Evinrude/Johnson's 5W40 Ultra 4-Stroke blend, 10 ounces per fill, alongside 87-octane gas.

Who it suits

Its light weight makes it easy to carry, clamp on, and remove by hand, which fits uses like a kicker for a canoe, a dinghy on a larger boat, or a simple spare kept aboard. There's no electric start or alternator at this size, so it stays mechanically simple, with fewer parts to maintain between trips.

Coverage

Evinrude's 3-year, non-declining warranty applies to this engine.

Is this electric start? No, it's rope start only, with no alternator fitted.

How much does it weigh? 41 lbs.
