Thruster specs

Quick BTQ 185: specs, price and the boats it fits

Name: Quick BTQ 185
Brand: Quick

The BTQ 185 is Quick’s mid-size single-propeller bow thruster for boats of about 26 to 49 ft. It sits in a tube through the hull near the bow and comes in three strengths, about 121 to 209 lb of push on 12 or 24 V, so you can match it to your boat. Quick has made thrusters since 2007, and the BTQ name was in its 2012 catalog.

Prices start at $3,950 at Quick’s US store, for the thruster alone. You’ll want a control panel ($465 for the push-button one), the tube ($459 for a short one) and a fuse with its holder. The bigger models need a hefty battery bank. Batteries, cable and a charger add about $1,239 to $2,456, as the extra cost below shows.

Owners of Quick thrusters report two things worth knowing. The motor brushes wear over time, and Hanse owners have had them replaced along with a failed relay. And a long docking in strong wind can trip the overheat protection. Quick says the thruster isn’t made for continuous duty, so its panel stops the motor after about 5 minutes 40 seconds and waits 20 minutes. Quick backs it for three years.

The full spec sheet for a yard sits lower down, and the Quick thruster review covers Quick’s whole range.

What Quick says 26 to 36 ft The maker's own range, from its listing

What our sizing says 37 to 39 ft Full thrust in 15 knots. The longest boat of each kind is in the table.

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 sailboat gets full thrust to 37 ft, and a catamaran to 39 ft. The maker gives one range for every boat.

The table below tries the Quick BTQ 185 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 at the bow 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 up to 39 ft, just past Quick’s own range (26 to 36 ft).

The Quick BTQ 185 against each kind of boat, in a 15 knot wind. Our sizing, from the finder’s own rules.
Boat	Full thrust at 15 knots	Still a fit, in lighter wind
Pontoon & tritoon	Not listed. A pontoon has no hull body between the logs to bore a tunnel through, and nobody sells one for these boats.
Sailboat	31 to 37 ft	38 to 39 ftfull thrust to about 14 knots at 39 ft
Houseboat	None	30 to 39 ftfull thrust to about 11 knots at 39 ft
Catamaran	35 to 39 ft	None
Trawler	31 to 37 ft	38 to 39 ftfull thrust to about 14 knots at 39 ft
Motor yacht	35 to 37 ft	38 to 39 ftfull thrust to about 14 knots at 39 ft
Bass & flats	Not listed. Nobody sells a tunnel kit for these hulls, and a bass boat’s shallow planing bow has almost no depth to hold one.
Wake & ski boats	Not listed. Nobody sells a tunnel kit for these hulls.
Express cruiser	39 ft only	None
Center console	No length. More thrust than the boat needs.

Reading the two length columns. 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 falls short of what the boat needs by no more than 10 percent, and gives the whole figure only in the lighter wind named. On a boat shorter than the first column’s shortest length, the unit is more than the boat needs.

It is sized for six kinds of boat here. For your own boat, the finder gives an answer that also counts your drive and who does the fitting. The compare page sets this unit beside others.

What it costs fitted

These totals are our estimate of a yard job: the unit’s price, plus a yard’s hours at $160 to $180 an hour, plus the batteries, cable and charger, plus the other parts the box does not hold. A adds $540 to $1,880 at these lengths, with 5 to 7 days out of the water, worked from eight yards’ own rate cards. The hours come from what owners and yards report. Your own yard will have its own opinion. The cost page builds the same figures line by line.

How the batteries, cable and charger add up. We price a battery bank close to the thruster, as the makers recommend, with 10 to 20 ft of cable out and back: red for the positive, black for the negative, cut to length. The low end is the cheapest battery that meets the figure and the shorter run; the high end is a sealed (AGM) battery and the longer run. The charger is a NOCO GEN5X2 two-bank shore charger.

Batteries and lugs are priced at Fisheries Supply and the cable and charger at Defender, read 12 October 2026.

At 12 V: one 12 V battery, at least 550 CCA and 115 Ah (Quick’s minimum), $998 for the battery; Quick’s cable table gives 1/0 to 3/0 AWG, priced on 1/0 to 4/0 AWG, the nearest size cut to length: $95 to $314 for the red and black cable and the lugs; a GEN5X2 charger, $146.
At 24 V: two 12 V batteries in series, at least 450 CCA and 80 Ah each (Quick’s minimum), $1,147 for both; Quick’s cable table gives 1 to 1/0 AWG: $80 to $171 for the red and black cable and the lugs; a GEN5X2 charger, $146.

What else you buy

What follows comes from Quick’s BTQ Series installation manual REV 005A and the TCD control manual, September 2025, read 30 September 2026.

In the box: The thruster with its reversing contactor and anode, a drilling template, gasket, O-ring, the manual.
Bought separately: "Recommended Quick accessories not included": the TCD control panels, the line switch, the THF fuse holder. Plus the fuse, the cable, a battery disconnection switch, a 4 A control fuse and switch, the tube.
Charging: The manual gives a battery table by model, in amp-hours and cold cranking amps, and a diagram with the panel on the service battery. It says nothing about how the thruster bank is charged.

The manual’s words, page 10: “Standard supply and material included in the package: Thruster, Drilling template, Gasket, O-ring, Installation and use manual, Conditions of warranty.”

The “other parts” line in the estimate above is the priced parts below, $541 to $1,369 at Fisheries Supply’s prices on 30 September 2026. The batteries, cable and charger have a line of their own.

What holds up and what to weigh

Each point names the fact it rests on.

What holds up

It is sold at 12 V and at 24 V.The maker's and dealers' listings

What to weigh

The boat comes out of the water to fit it: it needs a tunnel bore below the waterline.The mounting: a bore through the hull, or a housing recessed into it

What the manual and listings say

This is the note we keep on the Quick BTQ 185, written from the maker’s manual, its product pages and the dealer’s listing.

In the box: The thruster, a drilling template, gasket and O-ring. The TCD panel and the fuse holder are bought.

BTQ 185-55, 55 KGF, single propeller, 12 V

Single propeller in a 185 mm tunnel. Quick is the brand Beneteau, Jeanneau and Hanse fit at the factory, so most owners meet it without having chosen it. The category page puts the whole BTQ 185 series on boats of 26 to 50 ft. The band here is the US store's own figure for this version.

The manual gives a 250 A fuse at 12 V and a weight of 16.7 kg. Its cable is 1 AWG for a total run under 5 m (positive plus negative), 2/0 to 10 m, 3/0 to 20 m. At 24 V the fuse is 150 A and the cable one size down in every band.

The manual prints a fuse and cable sizes but no current draw and no battery figure. No product page gives a run time. The installation manual says the unit is not designed for continuous use and leaves the limit to the control panel. The panel's own manual cuts the command after about five minutes and resets it after a cool-down the panel computes.

The tunnel sits at least three quarters of its diameter below the waterline. Once a year the unit comes apart for inspection, anode included. The warranty runs three years from purchase, with repair or replacement at Quick's discretion. The warranty is void for maintenance by anyone Quick has not authorized or for non-original parts. Removal and refitting are at your cost.

Quick announced a brushless QSY range in September 2026, rated for ten minutes' continuous running. The QSY range will sit beside this brushed line. The price is Quick's US store, $3,475.85 at 24 V and $3,949.57 at 12 V, read 11 October. The price is Quick's US store's own for this size at 12 V, read 12 October.

The price is Quick's US store's own for this size at 24 V, read 12 October.

BTQ 185-75, 75 KGF, single propeller, 12 V

The 75 kgf BTQ 185, single propeller. The manual gives a 350 A fuse at 12 V and a weight of 17.0 kg. Its cable is 2/0 for a total run under 5 m (positive plus negative), two 1 AWG per leg to 10 m, two 2/0 AWG per leg to 20 m. At 24 V the fuse is 250 A and the cable 1 AWG, 2/0 and 3/0 by band.

BTQ 185-95, 95 KGF, single propeller, 12 V

The biggest single-propeller Quick, 95 kgf in a 185 mm tunnel. The manual gives a 350 A fuse at 12 V and a weight of 26.6 kg. Its cable is two 1 AWG per leg for a total run under 5 m (positive plus negative), two 2/0 AWG per leg to 10 m, two 3/0 AWG per leg to 20 m.
