About the VETUS Bow Pro Boosted 150
The Bow Pro Boosted 150 moves up to the larger tube size and gives 331 lb of variable push, for boats of about 40 to 60 ft. Its own batteries at the bow are kept charged by a built-in charger from your 12 V system, and the push holds steady as they run down.
Fisheries Supply lists it at $7,018. Expect about $635 to $1,634 for the tube, a control panel, a main switch and fuses, and budget for the two batteries it runs from at the bow; with cable we estimate $1,955 to $2,031. See what else to buy.

One thing to know: VETUS’s installation manual gives this model a shorter run rating than its product page does, so treat the manual’s figure as the limit until a dealer says otherwise. There are no brushes to maintain, the zinc gets changed yearly, and the warranty is three years through the dealer.
The full spec sheet for a yard sits lower down, and the VETUS thruster review covers VETUS’s whole range.

Will the VETUS Bow Pro Boosted 150 steer your boat?
66 FT TRAWLER · BOW · 15 KT WIND
Every knot figure here is wind speed, not boat speed or current.
On a 66 ft trawler the VETUS Bow Pro Boosted 150 (331 lb) steers her in a 16 knot breeze. Her bow needs about 293 lb from a tunnel to steer her in a 15 knot breeze.
The finder lists it for her.

Is it right for your boat?
Every kind of boat it fits, by length
| Boat | Full thrust at 15 knots | Still a fit, in lighter wind |

The VETUS Bow Pro Boosted 150 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 54 ft, and a sailboat to 66 ft. The maker gives one range for every boat.
The table tries the VETUS Bow Pro Boosted 150 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 38 ft and up to 66 ft, just past VETUS’s own range (40 to 60 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 |
|---|---|
| 38 ft | $15,408 to $20,073$47 to $61 a lb of thrust |
| 50 ft | $15,718 to $25,693$47 to $78 a lb of thrust |
| 66 ft | $15,988 to $26,463$48 to $80 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 $680 to $3,180 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.
| Boat length | The unit | Yard labor | Haul-out | Batteries, cable, charger | Other parts |
|---|---|---|---|---|---|
| 38 ft | $7,018 | $5,120 to $7,56032 to 42 hours | $680 to $1,830 | $1,955 to $2,031 | $635 to $1,634 |

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 24 V: two 12 V batteries in series, at least 170 Ah each (VETUS’s minimum), $1,860 for both; VETUS’s cable table gives 1/0 AWG: $95 to $171 for the red and black cable and the lugs; no charger, as the unit carries its own.

- 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.

Every step, and who does it
- Cut, bond and fair the tunnel; fit the gear leg, motor and propeller Yard 32 to 70 hours The low end is two crew over two days, the job as owners describe it on the forums. The high end rises with boat length between two real billed figures: 32 hours at 35 ft, and the largest invoice we hold, 70 hours at 47 ft.
- 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.

Know before you buy
What sets this model apart, what it costs to keep, and what to weigh.
Price per pound of thrust
$21.20 a lb The unit’s price over its published thrust. The bars are VETUS’s next sizes and the nearest other makers.Controls
A charger is built in (12 V, 80 A), fed from the boat's own bank. Proportional: the joystick sets how hard it pushes. The thruster fuse sits in the connection unit.
Pricey wear part: anodes
$85.21 a change- Zinc anode (SET0151): $85.21 at Fisheries Supply.
A change costs $85.21. That is over twice the $33.75 for Sleipner’s anode on the same 250 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
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 24 V it wants two batteries of 170 Ah or more, VETUS's figure. The cheapest that meets it is the Mastervolt 8D AGM start / deep cycle, $930.00. Check your own bank.
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.

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 BOW PRO Boosted 250 mm installation manual 020809.06 r8, December 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. The thruster fuse sits 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
- The manual wants the thruster on its own battery or batteries, close by, and sealed batteries if they share its compartment. The Boosted unit carries its own charger (12 V, 80 A), fed from the boat's bank through a fused cable.
The manual’s words, page 22: “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 covers these parts as a range, $635 to $1,634 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.

Our notes from the manual and listings
In the box: A charger is built in (12 V, 80 A), fed from the boat's own bank. Proportional: the joystick sets how hard it pushes. The thruster fuse sits in the connection unit.
Our note
A 12/24 V unit in a 250 mm tunnel. Boosted means the thruster runs on its own bank, which the boat's system charges through a built-in charger. The 250 mm manual prints no feed-cable table. It is brushless and proportional, so the joystick sets how hard it pushes instead of switching it on and off.
The installation manual rates this one at 6 minutes (S2), where the 180 and 210 in the same manual get 10. The product page prints 10. The user manual says run time is mainly limited by the battery. The US press release's "unlimited runtime" appears in neither. The manual gives 242 A at 24 V (276 at 21) and an example battery of two 170 Ah 12 V batteries.
It calls for a 355 A main fuse and a 300 A fuse in the controller that must stay in place. It gives 1 AWG cable to 20.7 ft of total run. 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.
Where each point above comes from
