Outboard repowering in South Carolina

Repowering means putting a new outboard on the boat you already own, and it's often the smartest money in boating, because hulls outlast motors by decades. Coastal Marine does the whole job in house on Highway 544, with new Yamaha and Suzuki outboards in stock and the area's only Yamaha Certified Master Technician in the bays.

Repower jobs we handle

Two-stroke to four-stroke swaps

The classic repower. Weight check on the transom first, then the quote.

Brand switches

Moving from another brand to Yamaha or Suzuki, with the rigging swap inside the one price.

Pontoon and tritoon repowers

More shove for the river boat without replacing the boat.

Bay boat and console repowers

Single motors and twin setups for the boats that work the salt.

Controls and gauge upgrades

Older cable setups brought current while the motor’s off anyway.

Service after the swap

The same bays handle every service the motor ever needs.

Pick your repower brand

Yamaha repowering

Installed by the area’s only Yamaha Certified Master Technician, with the motors already in stock.

Suzuki repowering

Usually the sharpest price for the same horsepower, installed by Suzuki certified technicians.

Signs the old motor is done

An aging motor usually tells you. The question is whether you're listening:

If two or three of those sound familiar, run the math before the next repair. Add up what the motor has cost you over the last two seasons and weigh it against the price of a new one, with its warranty, its fuel economy and its cold-morning starts.

  • Repair bills landing closer together every season.
  • Hard starting that's become part of the launch routine.
  • A compression test your mechanic frowns at.
  • Parts for an old two-stroke getting harder to find.
  • A fuel bill a modern four-stroke would cut noticeably.

What's included in a repower here

The quote covers the whole job, not a motor on a pallet:

  • Removal of the old motor.
  • The new Yamaha or Suzuki, usually straight from stock in the building.
  • Controls, cables and gauges, matched to what your boat actually needs.
  • A prop sized to how you load the boat.
  • Rigging labor, fluids and sales tax.

One number, out the door. We'll put the repair estimate for your current motor right next to it and tell you which one we'd pick if it were our boat.

What it costs

No two quotes match because no two boats match, horsepower drives the number and rigging rides on top of it. As one real reference point, a Suzuki DF140 repower on an 18-foot bay boat typically lands in the low twenties installed. Smaller motors land well under that, big offshore power lands above it.

How the job runs

  1. 1

    The fit check

    A new four-stroke often weighs more than the old two-stroke it replaces, so we verify the boat's weight rating and the mounting before quoting anything.

  2. 2

    The quote

    One installed, out-the-door number, with the repair option priced beside it.

  3. 3

    The swap

    Old motor off, new Yamaha or Suzuki rigged with the right controls and prop.

  4. 4

    The after

    The same bays handle every service the motor ever needs, with its history on file where it was installed.

Repower questions we hear every week

Only up to what the boat is rated for. The capacity plate and the transom rating decide, not optimism, and we check both before quoting anything.

A sound hull with a tired motor is the best repower candidate there is. A soft transom isn't, and if that's what we find, we'll tell you before you spend a dollar.

It moves with the season and the rigging, but the longest wait in most repower timelines is the factory order for the motor, and ours are already in the building.

Yes. Plenty of repowers roll through here on boats that never came off this lot.
