Why Twin 100s? (Control, Confidence, and Cost That Makes Sense)

Twins aren’t just about speed. They’re about control when you’re docking in a crosswind, redundancy when family or clients are aboard, and balanced performance on 20–26 ft boats that like even weight on the transom.

• Maneuverability: Independent throttles make close‑quarters handling easier.

• Redundancy: If one engine needs attention offshore, you’re not calling for a tow.

• Economy & Noise: Yamaha 100s deliver quiet four‑stroke operation and efficient cruise.

• Resale: U.S. buyers love twin setups on coastal and Great Lakes boats—smart for long‑term value.Used Yamaha 100hp Twin Outboard Motor for sale

What to Check Before You Buy (The Twin‑Specific Buyer’s Checklist)

Matched Pair Credentials

Ask for serial verification and model matching. Ideally, the pair should be same generation and hours within a reasonable range. Used Yamaha 100hp Twin Outboard Motor for sale

Rotation & Steering

Some 100 HP lines may not offer counter‑rotation in certain years. That’s okay—many twin‑100 rigs run standard rotation on both. We’ll advise on prop selection and steering setup to keep torque steer civilized.

Controls & Rigging (Mechanical vs. DEC)

Most Yamaha 100s are mechanical throttle/shift. Good news: mechanical twins are budget‑friendly. We confirm compatibility with your helm and can bundle dual binnacle, harnesses, key switch, and gauges when available.

Shaft Length & Mounting

Check your transom: 20″ (L) and 25″ (XL) are common. Twins must match height and mounting holes for clean alignment and cooling.

Diagnostics That Matter

• ECU hours and fault‑code scan (for each engine)

• Compression & leak‑down test (even numbers = happy weekends)

• Gearcase pressure/vacuum test (seal integrity)

• Charging output verification (electronics, livewells, and lights love steady volts) Used Yamaha 100hp Twin Outboard Motor for sale

Salt vs. Fresh History

Salt is fine with the right care. Review anodes, paint, brackets, and wiring cleanliness. Our high‑resolution photos and inspection notes make it easy to judge.

What’s in the Box

Twins can save big if they include controls, harnesses, key switch, gauges, and props. We label inclusions clearly so you’re not chasing parts after delivery.
