500 HP Outboard Motors
500 horsepower suits large offshore hulls, almost always in pairs, triples or quads. Expect 450 kg and up, 990 lb and up dry, which is the figure that decides whether one person can lift it on and off a transom.

Buying used at this size, nothing on the market is exactly five hundred horsepower; the class runs from the 400hp V8s to the 600hp V12, so decide on the hull rating first.
Listed prices on this page run from $8,464 to $35,000. Freight, controls and a propeller are quoted separately.
Common questions
What size boat does a 500hp outboard suit?
It suits large offshore hulls, almost always in pairs, triples or quads. 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 500hp outboard weigh?
Typically 450 kg and up, 990 lb and up. 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.
