The Northeast’s #1 Yamaha Retailer
Monahan’s Marine has proudly partnered with Yamaha for decades, earning our spot as the top-volume Yamaha outboard retailer in the Northeast. From dinghy kickers to flagship offshore V8s, no one in the region moves — or services — more Yamaha power than we do.
That volume comes with the deepest parts inventory on the South Shore, a full staff of Yamaha-certified technicians, and direct factory support. When you buy Yamaha from Monahan’s, you’re not just getting an engine — you’re getting the expertise to rig it, run it, and keep it running for years to come.
The Right Engine for Your Boat
As an authorized Yamaha outboard dealer, Monahan’s Marine carries the full lineup — from portable 2.5 HP motors for tenders and dinghies to the flagship 425 HP XTO Offshore for serious center consoles.
Our Yamaha-certified technicians handle every re-power from start to finish: engine selection, rigging, controls, gauges, prop matching, and sea trial. We don’t just bolt on a motor — we build a complete, turnkey power package.
Benefits of Re-Powering
A new engine transforms the boating experience. Here’s why it makes sense.
Better Fuel Economy
Modern Yamaha four-strokes deliver dramatically better fuel efficiency than older engines. Spend less on gas, more time on the water.
Proven Reliability
Yamaha outboards are built to last. Less downtime, fewer repairs, and the confidence that your engine will start every time.
Factory Warranty
Every new Yamaha outboard comes with a factory warranty. Re-power with peace of mind knowing you're fully covered.
More Power, Less Weight
Yamaha's latest designs pack more horsepower into lighter packages. Better hole shot, better top end, better handling.
Quieter Operation
Advanced engineering means less noise and vibration. Enjoy the ride, hear the conversation, and feel the difference.
Higher Resale Value
A fresh Yamaha outboard on the transom instantly increases your boat's market value. It's an investment that pays off.
