About the VETUS Bow 95
The Bow 95 is the big push-button VETUS for boats of about 36 to 55 ft, giving 210 to 231 lb of push. It has a long record on trawlers and sedan cruisers, and its plain on/off control is easy for anyone aboard to use.
US dealers sell it for $3,511, the same at 12 V or 24 V. Expect around $533 to $1,358 more for its tube, a panel at the helm, the main switch and a fuse. It needs its own battery bank close to the bow, and with cable and charging we estimate $739 to $1,101. See the full list.

One owner of a converted Navy utility trawler ran a 2006 Bow 95 for years, then had the motor rebuilt at a local alternator shop in about ten days for less than half the price of a new one. VETUS rates it for 3 minutes at a time on 12 V and 3.5 on 24 V. Check brushes and zinc every year. The warranty runs three years.
The full spec sheet for a yard sits lower down, and the VETUS thruster review covers VETUS’s whole range.

Will the VETUS Bow 95 steer your boat?
57 FT TRAWLER · BOW · 15 KT WIND
Every knot figure here is wind speed, not boat speed or current.
On a 57 ft trawler the VETUS Bow 95 (210 lb) steers her in a 15 knot breeze. Her bow needs about 218 lb from a tunnel 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. It shows the Bow 95 at 24 V for her instead.

The VETUS Bow 95 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 43 ft, and a catamaran to 60 ft. The maker gives one range for every boat.
The table tries the VETUS Bow 95 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 33 ft and up to 60 ft, just past VETUS’s own range (36 to 55 ft).
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 installing. The compare page sets this unit beside others.
What it costs installed
A yard job, everything in. Our estimate.
| Boat | Total installed |
|---|---|
| 33 ft | $10,523 to $13,320$50 to $63 a lb of thrust |
| 45 ft | $10,733 to $19,660$51 to $94 a lb of thrust |
| 60 ft | $11,093 to $21,470$53 to $102 a lb of thrust |
From the shortest to the longest boat it is sized for.
What is in each total
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 $590 to $2,900 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. The cost page builds the same figures line by line.

For every length in the table above.
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 26 October 2026.
- At 12 V: one 12 V battery, at least 1,083 CCA (VETUS’s minimum), $443 to $552 for the battery; VETUS’s cable table gives 3/0 to 2 x 2/0 AWG, priced on 4/0 to 2 x 2/0 AWG, the nearest size cut to length: $180 to $403 for the red and black cable and the lugs; a GEN5X2 charger, $146.

The VETUS Bow 95 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 45 ft, and a sailboat to 60 ft. The maker gives one range for every boat.
The table tries the VETUS Bow 95 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 33 ft and up to 60 ft, just past VETUS’s own range (36 to 55 ft).
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 installing. The compare page sets this unit beside others.

Pricey wear part: anodes
$76.98 a change- Zinc anode (SET0150): $76.98 at Fisheries Supply.
A change costs $76.98. That is over three times the $20.89 for Lewmar’s anode on the same 185 mm tunnel (589350, Fisheries Supply). An anode is a plain block of metal that wears away by design, so you will buy it again.

Service and warranty
VETUS gives 3 years, or 1 for professional use, and it transfers to the next owner. Claims go through the dealer only. It is void unless an authorized VETUS dealer does the periodic maintenance, and transport, labor and lifting are excluded.
See VETUS’s warranty VETUS's warranty policy.Special mentions
Battery: at 12 V it wants one battery of 1,083 CCA or more, VETUS's figure. The cheapest that meets it is the Dyno Group 8D heavy duty marine starting (flooded), $443.02. A sealed one is the Lifeline GPL-3100HC Group 31 AGM starting, $551.95. Check your own bank.
Charger: a NOCO GEN5X2 two-bank shore charger, $146.41. It is the one our estimate prices.
Gas engine room? Buy the ignition-protected VETUS Bow 95 Ignition Protected, $4,343.
Dealer prices at Fisheries Supply, read 26 October 2026.What to weigh
The boat comes out of the water to install it: it needs a tunnel bore below the waterline.
Short pushes only: VETUS rates the motor for 3 min at a stretch.
At 12 V it draws 650 A, so the battery cable is heavy and the battery sits close to it.

For the install what the box leaves you to buy
The manual button above opens it on the maker's site. It has the hull, wiring and fuse figures for this model.
From VETUS’s BOW95D installation manual 020526.08 r7, January 2025, read 25 October 2026.
- In the box
- The manual prints no box list. It says the thruster is supplied with a zinc anode and has you drill with the template that comes with it.
- 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
- The manual wants the thruster on its own battery or batteries, close by so the power cables stay short, and sealed batteries if they share its compartment. Its wiring diagram shows an alternator and a battery separator, and it says nothing more about charging.
The manual’s words, page 22: “We also recommend that each bow thruster is powered by its own separate battery or batteries.”
The “other parts” line in the estimate above covers these parts as a range, $533 to $1,358 at Fisheries Supply’s prices on 30 September 2026 and 26 October 2026, because the exact items depend on your boat. The batteries, cable and charger have a line of their own. The cost page has what every maker says about each part.
Tunnel tube
Fisheries Supply lists it as “VETUS fiberglass tunnel tube, 185 mm bore, 40 in”.
Sold in lengths from about 40 to 60 in. This is the shortest: the yard cuts the tube to the width of your hull at the thruster.
Control panel
Fisheries Supply lists it as “VETUS push-button thruster panel with time delay”.
Control cable, panel to thruster
Fisheries Supply lists it as “VETUS bow thruster control cable, 6 m”.
Sold in lengths from 6 to 20 m. This is the shortest: measure the run from the helm to the thruster and buy the length that reaches.
Main fuse
Ask for 425 A (VETUS ZE425). This one is for the 12 V version.
A VETUS strip fuse in its own holder (VETUS ZEHC100). Not listed at Fisheries Supply; ask a VETUS dealer.
Main fuse
Ask for 200 A (VETUS ZE200). This one is for the 24 V version.
A VETUS strip fuse in its own holder (VETUS ZEHC100). Not listed at Fisheries Supply; ask a VETUS dealer.
Fuse holder

Batteries
Fisheries Supply lists it as “Lifeline GPL-1400T AGM starting”. This one is for the 24 V version.
You need 2, each at 533 CCA 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 4/0 AWG, cut to length, red or black”. This one is for the 12 V version.
This is the short run. A longer run takes heavier cable: the wiring calculator sizes yours. You need 5 ft of each color. For about 10 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.
Battery cable, red and black
Defender lists it as “Ancor tinned battery cable 1 AWG, cut to length, red or black”. This one is for the 24 V version.
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.
Cable lugs
Fisheries Supply lists it as “Tin-plated starter lugs, 4/0 AWG, bag of 10”. This one is for the 12 V version.
This is the short run. A longer run takes heavier cable: the wiring calculator sizes yours. The listing runs $47.52 to $49.44 by stud size. Eight ends on one run, with two spare.
Cable lugs
Fisheries Supply lists it as “Tin-plated starter lugs, 1 AWG, bag of 10”. This one is for the 24 V version.

Our notes from the manual and listings
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 manual gives 650 A, a battery of 1083 to 2166 cold cranking amps and a 425 A fuse. For cable it gives 1 AWG to 8.5 ft of total run (positive plus negative), and 4/0 to 20.7 ft. The motor is brushed. The manual rates it for 3 minutes at a time, or 3 per hour, at 650 A.
Brushes and anode are checked yearly, and no copper-based antifouling goes on the unit. The product page prints 610 A where the manual says 650. From 95 kgf up the manual's minimum brush length is 16 mm, not 14. 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 BOW95 on two 12 V batteries in series. The manual gives 320 A, a battery of 533 to 1067 cold cranking amps and a 200 A fuse. For cable it gives 4 AWG to 17.7 ft of total run (positive plus negative), and 4/0 to 85.3 ft. The manual rates it for 3.5 minutes at a time, or 3.5 per hour, at 320 A.
