Mercury Authorized Dealer

Engine Installation

Engine installation is one of the most critical services a marine dealership can offer — and it's one we take seriously. As an authorized Mercury Marine dealer, our certified technicians install outboard, inboard, and MerCruiser sterndrive engines to exact factory specifications.

Whether you're repowering an aging vessel, upgrading to a more fuel-efficient engine, or dropping a new motor onto a freshly purchased hull, we handle every detail. From mounting and rigging to fuel system integration, wiring, controls, and a full on-water sea trial — we don't hand back the keys until everything is dialed in perfectly.

Mercury Authorized

Certified installation to factory specs with full warranty protection on every engine we install.

Complete Rigging

Controls, fuel lines, electrical, throttle & shift — full rigging done right, not rushed.

All Engine Types

Outboards, inboards, and MerCruiser sterndrives across the full range of marine systems.
