3.5 HP Outboard Motors

3.5 horsepower suits tenders and light dinghies where every kilo counts. Expect 18 to 20 kg, 40 to 44 lb dry, which is the figure that decides whether one person can lift it on and off a transom.

Buying a 3.5hp outboard

At this size you normally find short shaft, manual start, tiller, with integral, with an external connection on most.

We do not hold one at this size on the floor, but the engines below can be sourced and delivered in seven to fourteen days.

Buying used at this size, check the tilt lock and the transom clamps, which take a beating on a tender.

Listed prices on this page run from $395 to $1,950. Freight, controls and a propeller are quoted separately.

Common questions

What size boat does a 3.5hp outboard suit?

It suits tenders and light dinghies where every kilo counts. Always check the capacity plate at your transom first, since that gives the maximum the hull is rated for and it is illegal as well as unwise to exceed it.

How much does a 3.5hp outboard weigh?

Typically 18 to 20 kg, 40 to 44 lb. That figure matters more than most buyers expect: it decides whether you can lift the engine alone, and whether your transom bracket is rated for it.

Which shaft length do I need?

Measure vertically from the top of the transom to the lowest point of the hull. Fifteen inches takes a short shaft, twenty inches a long shaft, twenty five inches an extra long. Fitted right, the anti ventilation plate finishes level with the hull bottom. Send us a photograph with a tape measure in frame if you are unsure.

Does the price include controls and a propeller?

Remote steering engines are supplied without a control box or cables unless you add them, and engines from 40hp up ship without a propeller so it can be pitched to your hull. Both can go in the same crate, so there is no second freight charge.

How does it get to me?

Crated and shipped to all 48 states. Freight is priced from your zip code against the destination zone, and the exact figure is shown at checkout before you pay. Ask for a written quote first if you would rather see it in an email.
