How Much Does a Mercury Repower Cost?

The single most common question we get at Gearhead Marine is “what will it cost to repower my boat?” The honest answer is that it depends — but the variables are predictable. Here is what goes into a Mercury repower quote.

1. Horsepower and engine family

A 90 HP FourStroke and a 300 HP Verado are very different investments. Higher horsepower, supercharged Verado, and Mercury Racing power cost more than mid-range FourStroke outboards. Browse current options on our Mercury outboards page to see real pricing.

2. Outboard vs. sterndrive

An outboard swap is usually simpler than a MerCruiser sterndrive repower, which may involve the engine, the drive, and the transom assembly. Buying a matched sterndrive package keeps the gear ratio and drive correct and simplifies the job.

3. Rigging, controls and props

Switching brands or moving to digital throttle & shift (DTS) can mean new controls, gauges, harnesses and rigging. The right propeller is critical to getting the performance you paid for.

4. Labor and installation

Clean installs take skilled labor. Gearhead Marine's certified technicians rig every repower properly and water-test the result. We also offer mobile service.

Frequently Asked Questions

What does a Mercury repower cost?

A Mercury repower price is driven by horsepower and engine family, whether you are replacing an outboard or a full MerCruiser sterndrive, new rigging and controls, the propeller, and installation labor. Gearhead Marine quotes each boat individually — call (951) 299-8024 for a written number.

Is repowering cheaper than buying a new boat?

In most cases yes. A repower replaces the single most expensive mechanical component while keeping the hull, trailer, electronics and interior you already own, so it is usually a fraction of the cost of replacing the whole boat.

Does a sterndrive repower cost more than an outboard?

Usually. An outboard swap is typically a simpler job, while a MerCruiser sterndrive repower can involve the engine, the drive and the transom assembly. Buying a matched sterndrive package keeps the gear ratio and drive correct and simplifies the work.
