About the Yacht Thruster Duplex 600D
The Duplex 600D puts two motors in one long pod, Yacht Thruster’s answer for bigger boats of 56 to 66 ft at the bow. Like the smaller Simplex it hangs outside the hull, at either end, so a large boat gets strong control at the bow or stern with no tunnel through her and no space lost below. It is rated 397 lb, a “thrust equivalent”, the push times 1.4; our size tables use Sleipner’s measured 287 lb for the same pod.
There is no published price; Yacht Thruster quotes each boat. The kit includes the control box and a joystick or touchpad. At 24 V the two motors together draw several hundred amps, so plan a short, heavy cable run from a 24 V bank near the unit, about $700 to $731 on our estimate for the batteries, cable and charger. See every part.

Installing it means a haul-out and three holes through the hull: one sealed fitting for the cables and two for the mounting rods. The housing is aluminum, so it takes antifouling over a suitable primer and must not touch a steel or aluminum hull directly. It runs up to five minutes at a time and about twenty-five minutes in an hour, which covers a long docking.
The full spec sheet for a yard sits lower down, and the Yacht Thruster and ezDrive review covers Yacht Thruster’s whole range.

Will the Yacht Thruster Duplex 600D Thruster steer your boat?
67 FT TRAWLER · BOW · 15 KT WIND
Every knot figure here is wind speed, not boat speed or current.
On a 67 ft trawler the Yacht Thruster Duplex 600D Thruster (397 lb, which counts as about 210 lb on its own lever here) steers her in a 15 knot breeze. Her bow needs about 220 lb from an external unit at the very bow to steer her in a 15 knot breeze. Its 210 lb lands within 15 percent of that figure, which this site counts as enough.
The finder leaves it off her list. We found no published price for Yacht Thruster, and the finder lists only units it can price.

Outlined: the finder does not list it at that length (under 13 kt, far more than she needs, or outside Yacht Thruster’s own length range).
Two of them, one at each end
With a unit at each end she turns in her own length. One thruster on its own cannot turn her that way. On a 67 ft trawler:
Turns her in her own length
Turns her at 21 kt
Bow one way, stern the other, and she pivots about her middle.
- Under 10 kt
- 10 to 15 kt
- 15 to 20 kt: the sweet spot
- Over 20 kt: more than she needs
Prices are the low end of the installed total, from our estimate. For your own boat, drive and installer, the finder prices each unit.

The Yacht Thruster Duplex 600D Thruster against each kind of boat, in a 15 knot wind. Our sizing, from the finder’s own rules.
The first column is where one unit gives all the thrust the boat needs in 15 knots. The second is where the finder still lists it: the unit steers her in a 13 or 14 knot wind, within 15 percent of the 15 knot breeze this site sizes for. On a boat shorter than the first column’s shortest length, the unit is more than the boat needs.
How we size it
Our figure is the longest boat one unit can steer in a 15 knot wind. It is a range because each kind of boat catches the wind differently. Here a trawler gets full thrust to 67 ft, and a sailboat to 68 ft. The maker gives one range for every boat.
The table tries the Yacht Thruster Duplex 600D Thruster on each kind of boat, at every length that kind of boat is built in. The wind is 15 knots and the rules are the finder’s own. A length counts as a fit when the unit gives the thrust that boat needs where it mounts and the maker lists it for that length.
A boat up to 10 percent past the maker’s range still counts here, as it does in the finder. So the table runs down to 51 ft and up to 72 ft, just past Yacht Thruster’s own range (56 to 66 ft).
It is sized for three kinds of boat here. For your own boat, the finder gives an answer that also counts your drive and who does the installing. The compare page sets this unit beside others.
What it costs installed
No US dollar price is published for the Yacht Thruster Duplex 600D Thruster, so we build no total for it. The yard’s share of the job is on the cost page.
The sizing and the costs on this page are estimates, for guidance only and without warranty. They are no quote, and nobody has inspected your boat. Check them against the maker’s manual and your yard before you rely on them. Terms of use.

DIY levels
- Level 5: Owner install. No yard, no electrician.
- Level 4: You install it, electrician connects. You mount and wire it; a marine electrician makes the final connections.
- Level 3: Split with the yard. The yard does the below-waterline part; you do the wiring.
- Level 2: Wiring prep only. The yard installs the unit and does the hull work; you do the wiring prep.
- Level 1: Yard job. A qualified professional does all of it.

- Mount the battery box, switch and fuse holder; run and secure the cables You 4 to 16 hours Our estimate. No maker times this step, and a first-time owner is slower than a yard, so the range is wide.
- Final connections at the battery and the motor, load test Electrician 2 to 4 hours Our estimate. Nobody publishes a time for the final connections and test on their own.
A qualified marine electrician should make the final connections and test them before first use. Hours are labor only.

Service and warranty
Yacht Thruster's FAQ gives 2 years, and its product pages give 3.
See Yacht Thruster’s warranty Yacht Thruster's FAQ.Special mentions
Battery: at 24 V it wants two batteries of 397 CCA, sized to the draw. The cheapest that meets it is the Lifeline GPL-1400T AGM starting, $256.72. Check your own bank.
Charger: a NOCO GEN5X2 two-bank shore charger, $146.41. It is the one our estimate prices.
Yacht Thruster sells it for either end, so it can go at the bow or the stern.
Dealer prices at Fisheries Supply, read 26 October 2026.What to weigh
The boat comes out of the water to install it: it needs three small holes, below the waterline.
It bolts under the hull about 15% of her length back from the bow, not at the very end, so the boat tables on this page count its 287 lb of push as worth about 210 lb from a unit right at the bow.
Yacht Thruster's 397 lb is a "thrust equivalent" that already adds credit for the position, so we judge it on the push and work the position out ourselves.
No US dollar price is published for it, so we can work out no installed cost.

For the install what the box leaves you to buy
From Yacht Thruster’s Overview and FAQ pages, read 30 September 2026.
- In the box
- The thruster with its through-hull fitting and seals, the rods and seals of the mounting kit, the control box and controls.
- Bought separately
- Fuse, switch, cable and battery are not named on either page.
- Charging
- A 12 V unit may share the boat's supply, even a windlass feed if a specialist agrees. A 24 V unit on a 12 V boat needs a bank of its own. Neither page names a charger.
In Yacht Thruster’s words, from the FAQ: “In order to run a 24V Yacht Thruster with an on-board voltage of 12V, an additional 24V battery bank will be required.”
A yard job adds these parts on top of the unit: $88 to $268 for the priced ones, at Fisheries Supply’s prices on 26 October 2026, plus the batteries, cable and charger. The cost page has what every maker says about each part.

Batteries
Fisheries Supply lists it as “Lifeline GPL-1400T AGM starting”.
You need 2, each at 397 CCA (the motor’s draw; the maker prints no battery figure) or more, in series for 24 V. The cheapest listing that meets it.
Battery cable, red and black
Defender lists it as “Ancor tinned battery cable 4 AWG, cut to length, red or black”.
You need 10 ft of each color. For about 20 ft of cable in all, out and back. Measure your run and check it against the cable table in the manual: never go smaller than it asks for.

Our notes from the manual and listings
In the box: The through-hull fitting, its seals and the control box come with it.
Our note
Two 3 kW motors in one pod, rated 397 lbf at either end. It weighs 77 lb, is 38.5 in long and draws 397 A at 24 V. Yacht Thruster puts it on boats of 56 to 66 ft at the bow and 52 to 60 ft at the stern. It bolts through the hull below the waterline, so the boat comes out of the water to install it.
It takes one 2 in hole for the fitting and two 18 mm holes for the rods. Yacht Thruster puts the thruster itself at one to two hours once she is out. The FAQ gives a run time of up to five minutes continuous and 25 minutes an hour. The product pages promise a three-year warranty, where the FAQ says two. No price is published.
