About the Quick BTQ 300

The BTQ 300 is the largest bow thruster Quick sells in the US, made for yachts of about 65 to 99 ft. Two propellers in a big tube through the hull give about 551 or 595 lb of push on 24 V. Quick also lists a still larger 48 V model. It comes from a maker in the thruster business since 2007.

It starts at $11,962 at Quick’s US store, for the thruster alone. The control panel, tube and fuse come separately: Quick’s joystick is $540, the tube starts at $1,247 and the heavy-duty fuse holder is $209. Batteries, cable and charging add about $2,322 to $4,767 more. See below for the full list.

The drive coupling for this size is the priciest in the range, $607 at the store, and the motor brushes are the other part that wears. Quick calls the unit unsuited to continuous running, so the panel turns it off once a run nears 5 minutes 40 seconds, then rests it for 20 minutes. Quick asks for a yearly strip-down, and its three-year warranty is void if anyone it hasn’t authorized does that work.

Installers will find the wiring figures and dimensions further down. For the rest of Quick’s line, read the Quick thruster review.

The Quick BTQ 300 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 houseboat gets full thrust to 70 ft, and a sailboat to 80 ft. The maker gives one range for every boat.

The table tries the Quick BTQ 300 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 down to 59 ft, just past Quick’s own range (65 to 85 ft).

It is sized for five 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.

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.

Pricey wear part: anodes

$166.91 a change

A change costs $166.91. That is nearly five times the $33.75 for Sleipner’s anode on the same 300 mm tunnel (SM201180A, Defender). An anode is a plain block of metal that wears away by design, so you will buy it again.

They sit below the waterline, so a change means a haul-out or a diver.

Service and warranty

Quick gives at least 3 years from purchase, with repair or replacement at Quick's discretion. It is void if maintenance is done by anyone Quick has not authorized, or with parts that are not original. Removal and reinstalling are at your cost.

See Quick’s warranty Quick USA's conditions of warranty.

Special mentions

Battery: at 24 V it wants two batteries of 800 CCA and 150 Ah or more, Quick's figure. The cheapest that meets it is the Odyssey Extreme PC1800-FT start / deep cycle, $998.12.

Charger: a NOCO GEN5X2 two-bank shore charger, $146.41. It is the one our estimate prices.

The site’s reviewQuick thruster review

Every published figure the site holds for the Quick BTQ 300, with where each came from.

The tunnel: length and depth rules

Tunnel length. The optimal length is three to four times the tube diameter. A ratio of up to six can be tolerated. Longer tubes lose more of the thrust to friction. Quick’s installation manual.

Depth below the waterline. In the bow and as low as possible, at least 0.75 times the tunnel diameter below the waterline, to avoid cavitation at the propeller. BTQ250 and BTQ300 installation manual, REV006C.

Our notes from the manual and listings

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

BTQ 300-250, 250 KGF, double propeller, 24 V

The 250 kgf version, 24 V, with twin counter-rotating propellers in a 300 mm tunnel. The category page puts the whole BTQ 300 series on boats of 62 to 98 ft. The band here is the US store's own figure for this version. The manual gives a 400 A fuse at 24 V and a weight of 46.7 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 3/0 AWG per leg to 20 m. The US store page printed 77.2 lb for both BTQ 300 variants where the manual gives 46.7 kg for this one and 55.9 for the 270.

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 reinstalling 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's own for this size at 24 V, read 12 October.

BTQ 300-270, 270 KGF, double propeller, 24 V

The 270 kgf BTQ 300, twin counter-rotating propellers, 24 V. The manual gives a 500 A fuse at 24 V and a weight of 55.9 kg. Its cable is 3/0 for a total run under 5 m (positive plus negative), two 3/0 AWG per leg to 10 m, two 4/0 AWG per leg to 20 m. The manual's ladder tops out above it with a 48 V 300 kgf unit that no US page lists.

Where each point above comes from
  • The boat comes out of the water to install it: it needs a tunnel bore below the waterline.The mounting: a bore through the hull, or a housing recessed into it
