A Mercury 60 HP FourStroke Command Thrust can suit a heavier 18-foot deep-V aluminum boat that benefits from a larger gearcase and propeller. This is an illustrative planning example, not a completed customer job. HBW confirms the hull rating, gearcase choice, controls, propeller, engine height, and current written quote for the actual boat.

Quick answer: This illustrative scenario considers a Mercury 60 HP FourStroke Command Thrust repower on a properly rated 18-foot deep-V aluminum boat. The current bare-motor price is in the pricing reference; controls, propeller, removal, fuel-system work, rigging, and water testing require a boat-specific quote.

Key facts
- Old motor: standard Mercury 60 HP FourStroke
- New motor: Mercury 60 HP FourStroke Command Thrust
- Boat: 18-foot deep-V aluminum (heavy hull)
- Pricing: current bare motor in the pricing reference; installed quote depends on the boat and rigging
- Boat with us: 2 to 5 days (motor lead time separate)
- Same HP, bigger gearcase + higher-thrust prop
- Warranty: Mercury Limited Warranty, confirmed at quote
- Deposit: $500 for mid-range orders
What was on the boat before?
The candidate is a heavy 18-foot deep-V aluminum with a wide beam, full canvas, and a transom plate rated 60 HP. Owners often have a standard 60 HP FourStroke that came with the boat. Nothing is broken. The motor runs clean.
The planning complaint is slow loaded acceleration with two people, fishing gear, a full livewell, kicker, and fuel. HBW would first measure the existing setup, propeller, engine height, WOT RPM, load, and hull condition. With a 60 HP capacity-plate limit, any recommendation must stay within that rating.
Why upgrade to Command Thrust at the same HP?
Command Thrust is Mercury's heavy-hull gearcase. The horsepower rating stays at 60. What changes is the gearcase under the powerhead, a larger-diameter torpedo, larger gears, and a high-thrust prop with more blade area. The motor turns a lower gear ratio, which means each prop revolution moves more water.
The larger gearcase and propeller options may improve loaded acceleration and low-speed control. The exact planing time, top speed, trim behaviour, and cruise result depend on the actual hull, load, engine height, and selected propeller, so this scenario does not assign a guaranteed improvement.
Staying within the capacity-plate rating is mandatory. Command Thrust is a gearcase choice within the same horsepower rating, not a substitute for confirming that the complete motor and boat combination is approved.
What did the job involve?
A standard-to-Command-Thrust swap is mostly a propeller and gearcase change in terms of customer-visible difference, but it's a full motor swap under the cowl. We confirm the transom plate rating (the 60 HP cap stays valid), pull the old 60, inspect the transom and bracket, and mount the new Command Thrust 60 with new bolts. New controls and cables go in to match Mercury's current specs.
Propeller selection is boat-specific. HBW would choose the correct Command Thrust propeller family and verify loaded WOT RPM, acceleration, steering, and trim on the actual boat rather than prescribing a generic pitch range.
Water test on Rice Lake confirms WOT, hole shot, gauge function, and trim behaviour. Pickup-only at Gores Landing, we don't ship or deliver. See our repower process for the full sequence.
What did it cost?
Use the pricing reference for the current bare-motor price. The installed quote depends on controls, propeller, removal, fuel-system condition, steering, engine height, and any rigging that can be reused. Any trade value is assessed separately after the existing motor is identified and inspected.
HBW can arrange financing through DealerPlan and Canadian lenders on eligible purchases of $5,000 or more at the current 5.48% APR promotional APR through Dec 31, 2026 (OAC). The financed quote includes the $349 DealerPlan documentation fee where applicable and discloses the contract term, amortization, and any balance due at maturity. A $500 deposit holds the order.
Frequently Asked Questions
- What is Command Thrust on a Mercury outboard?
- Command Thrust is Mercury's heavy-hull gearcase option. Same horsepower as a standard motor, but a larger-diameter torpedo, bigger gears, and a high-thrust propeller. It pushes more water per revolution, which means better hole shot, better trim attitude, and more pull on heavy or oversized hulls.
- Will a Command Thrust 60 give me more top speed?
- Not really. Top speed is usually similar or slightly lower than a standard 60 because the gearing trades top-end for thrust. What you gain is hole shot, mid-range pull, and control of a heavy boat, exactly what a deep-V aluminum or heavy pontoon needs.
- Why not just go to a bigger HP standard motor?
- Sometimes a different horsepower is worth comparing, but the capacity plate is the hard ceiling. Command Thrust is one gearcase option at the rated 60 HP; HBW confirms the actual boat and load before recommending it.
- How long does the repower take?
- Two clocks. Your boat is with us for 2 to 5 days, drop-off to pickup, for a Mercury-to-Mercury swap on a clean transom. Motor lead time is separate: in-stock motors ship immediately, special orders wait at Mercury (the wait depends on the model and current Mercury availability), and your boat stays with you until the motor arrives. Pickup-only at Gores Landing.
