Thruster specs

VETUS Bow 60: specs, price and the boats it fits

The Bow 60 sits between the Bow 55 and the Bow 75 and gives 132 to 154 lb of push, the higher figure at 24 V, for boats of about 27 to 40 ft. It mounts in the same larger tube as the Bow 75 and Bow 95, and that tube, more than the thrust, sets the size of the yard job.

It sells for $2,243, the same price at 12 V or 24 V. The tube, panel, main switch and fuse come to about $533 to $1,358 more. Choosing 24 V means two batteries wired together at the bow instead of one, and our estimate for the battery side, with cable and charging, is $483 to $800. The full list is below.

Both versions are rated for 4 minutes of running at a time, longer than the bigger Bow 75 manages at 12 V. The motor is brushed: a yearly brush and zinc check keeps it healthy, and so does copper-free bottom paint on the unit. The warranty is three years when an authorized dealer does the servicing.

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

Is it right for your boat?

What VETUS says 27 to 40 ft The maker's own range, from its listing
What our sizing says 38 to 44 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 trawler gets full thrust to 38 ft, and a catamaran to 44 ft. The maker gives one range for every boat.

The table below tries the VETUS Bow 60 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 44 ft, just past VETUS’s own range (27 to 40 ft).

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 Lifting the boat out of the water on a travel lift or a trailer so work can be done below the waterline. It is billed separately from the job itself. adds $540 to $2,120 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 500 CCA (VETUS’s minimum), $257 for the battery; VETUS’s cable table gives 1 to 3/0 AWG, priced on 1 to 4/0 AWG, the nearest size cut to length: $80 to $314 for the red and black cable and the lugs; a GEN5X2 charger, $146.

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 31 ft, and a catamaran to 44 ft. The maker gives one range for every boat.

What else you buy

What follows comes from VETUS’s BOW55D installation manual 020522.11 r08 and the BOW PRO Boosted manual 020808.04 r09, May 2026 and February 2026, read 30 September 2026.

In the box
The unit assembled or in parts, the zinc anode, insulated gaskets, the drill template, the solenoid switches and the 5 A control fuse on the motor. BOW PRO: the thruster fuse in the connection unit.
Bought separately
The tunnel, the main switch (BATSW250 or BATSW600), the main fuse (ZE) and holder (ZEHC100), the cable, the control panel and its cable.
Charging
Every VETUS manual wants "its own separate battery or batteries" near the thruster, sealed if it shares the motor's compartment. The BOW PRO Boosted units carry a charger (12 V, 80 A) fed from the boat's bank, with a fused feed cable. The other manuals show an alternator and a battery separator on the wiring diagram and say nothing more.

The manual’s words, page 22 of the Boosted manual: “By connecting the 24 Volt battery bank to the MCVB boosted charge connection, the 48 Volt, battery bank is charged. An additional charging facility is not required.”

The “other parts” line in the estimate above is the priced parts below, $533 to $1,358 at Fisheries Supply’s prices on 30 September 2026. The batteries, cable and charger have a line of their own.

Parts the VETUS Bow 60’s box leaves to you, from the makers’ manuals read 30 September 2026. “What to ask for” is VETUS’s own part or model where its manual names one, otherwise the dealer’s item.

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 VETUS Bow 60, written from the maker’s manual, its product pages and the dealer’s listing.

In the box: The solenoid switches and the 5 A control fuse are on the motor. The panel, its cable, the main fuse and switch are bought.

12 V

A 185 mm tunnel, the hole the BOW75 and BOW95 share. So the tunnel and not the thrust sets the yard job. No VETUS manual for the 60 is in our files, so its current, battery and cable figures are not held here. The motor is brushed, and its brushes and anode are checked yearly. No copper-based antifouling goes on the unit.

Defender sells the 12 V and 24 V versions as one listing at one price. The warranty runs three years and is claimed through the dealer only. It is void unless an authorized VETUS dealer does the periodic maintenance, and labor, transport and lifting are excluded.

24 V

The 24 V BOW60 in the 185 mm tunnel the BOW75 and BOW95 share.

Videos

Two of VETUS’s own videos, from its YouTube channel: how VETUS picks a size, a battery bank and a panel, and the first of its service videos for a tunnel unit. They are the maker’s pitch. Watch them for what the unit looks like and how it goes in, and take any claim back to the figures above.

Other sizes and close alternatives

These are VETUS’s next sizes in the same line, by thrust.

  • One size down: VETUS Bow 55, two sizes, 121 to 132 lb, $2,137.
  • One size up: VETUS Bow 75, two sizes, 165 to 187 lb, $2,717.

These are other makers’ units of the same style, for the same end, within a quarter of its published thrust. Each is that maker’s nearest match.
