Thruster specs
Sleipner SRVP80 PRO: specs, price and the boats it fits
The SRVP80 adds speed control to the vertical-motor SRV80: up to 212 lb of push for boats of about 33 to 49 ft, at 12 or 24 V.
Imtra lists the 12 V thruster alone at $10,510, before a separate tariff line; the 24 V one has no price there. The manual gives 530 A and an ANL 400 fuse at 12 V. See the specs.
At full speed it runs 2 to 3 minutes; at lower settings it can keep going longer. It needs headroom over the hull for the upright motor. Warranty: two years.
Installers will find the wiring figures and dimensions further down. For the rest of Sleipner’s line, read the Sleipner (Side-Power) review.

How much of the install is yours
DIY levels
- Level 5: Owner install. No yard, no electrician.
- Level 4: You fit it, electrician connects. You mount and wire it; a marine electrician makes the final connections.
- Level 3: Split with the yard. The yard does the below-waterline part; you do the wiring.
- Level 2: Wiring prep only. The yard fits the unit and does the hull work; you do the wiring prep.
- Level 1: Yard job. A qualified professional does all of it.
You Yard Electrician. The bar is labor hours; a haul-out is a note.
How we rate DIYYou: 4 to 16 h Yard: 40 to 88 h Electrician: 2 to 4 h Plus a haul-out.
- Cut the hull and fit the housing and mechanism Yard 40 to 88 h Nobody publishes an hours figure. Fisheries Supply says installation is significantly more expensive than a tunnel, and that is too loose to turn into a number. So this is the tunnel’s own banded figure plus a quarter, which keeps it above a tunnel as the distributors describe it.
- Mount the battery box, switch and fuse holder; run and secure the cables You 4 to 16 h 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 h Our estimate. Nobody publishes a time for the final connections and test on their own.
Your part needs:Heavy battery cableCrimping big lugs
A qualified marine electrician should make the final connections and test them before first use. Hours are labor only.
Is it right for your boat?
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 36 ft, and a catamaran to 53 ft. The maker gives one range for every boat.
The table below tries the Sleipner SRVP80 PRO 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 31 ft and up to 53 ft, just past Sleipner’s own range (33 to 49 ft).
| Boat | Full thrust at 15 knots | Still a fit, in lighter wind |
|---|---|---|
| Pontoon & tritoon | Not listed. A retractable drops down inside the hull, and a pontoon has no hull depth to drop into. | |
| Sailboat | 41 to 49 ft | 50 to 53 ftfull thrust to about 14 knots at 53 ft |
| Houseboat | 31 to 36 ft | 37 to 53 ftfull thrust to about 10 knots at 53 ft |
| Catamaran | 46 to 53 ft | None |
| Trawler | 41 to 48 ft | 49 to 53 ftfull thrust to about 14 knots at 53 ft |
| Motor yacht | 41 to 48 ft | 49 to 53 ftfull thrust to about 14 knots at 53 ft |
| Bass & flats | Not listed. A retractable needs hull depth to drop into, and these planing hulls have almost none forward. | |
| Wake & ski boats | Not listed. A retractable needs hull depth to drop into, and these planing hulls have almost none forward. | |
| Express cruiser | 52 to 53 ft | 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 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 $550 to $2,560 at these lengths, with 5 to 7 days out of the water, worked from eight yards’ own rate cards. The hours are our own estimate. Your own yard will have its own opinion. The cost page builds the same figures line by line.
| Boat length | The unit | Yard labor | Haul-out | Batteries, cable, charger | Other parts | Total |
|---|---|---|---|---|---|---|
| 31 ft | $10,510 | $6,400 to $7,200about 40 hours | $550 to $1,500 | $703 to $1,007 | $336 to $815 | $18,499 to $21,032 |
| 40 ft | $10,510 | $6,400 to $10,80040 to 60 hours | $710 to $1,930 | $703 to $1,007 | $336 to $815 | $18,659 to $25,062 |
| 53 ft | $10,510 | $6,400 to $15,84040 to 88 hours | $1,040 to $2,560 | $703 to $1,007 | $336 to $815 | $18,989 to $30,732 |
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 1,045 CCA (Sleipner’s minimum), $443 to $552 for the battery; Sleipner’s cable table gives 2/0 AWG: $114 to $201 for the red and black cable and the lugs; a GEN5X2 charger, $146.
- At 24 V: two 12 V batteries in series, at least 570 CCA each (Sleipner’s minimum), $720 for both; Sleipner’s cable table gives 2 AWG, priced on 1 AWG, the nearest size cut to length: $80 to $141 for the red and black cable and the lugs; a GEN5X2 charger, $146.
The sizing and the costs on this page are estimates, for guidance only and without warranty. They are no quote, and nobody has inspected your boat. Check them against the maker’s manual and your yard before you rely on them. Terms of use.
What else you buy
What follows comes from Sleipner’s SE80 to SE150 installation guide, document 2687 rev 30, 2025, read 30 September 2026. That manual is written for the tunnel units. A retractable unit brings its own housing, so there is no tunnel to buy.
- In the box
- The gasket, bolts and anode come with the unit. The SEP guides call the power controller "the included PPC unit".
- Bought separately
- The ANL fuse and a main switch ("must include"), the control panel with its own guide, the panel cable and the battery cable.
- Charging
- The word "charging" is not in any of the Sleipner guides we read. The battery is sized by cold cranking amps, and a battery near the thruster is suggested. How it gets charged is left to you and your installer.
The manual’s words, page 19: “For installations on large vessels with bow and stern thrusters or catamarans a dedicated battery for each thruster should be considered.”
The “other parts” line in the estimate above is the priced parts below, $336 to $815 at Fisheries Supply’s prices on 30 September 2026. The batteries, cable and charger have a line of their own.

Draw, cable, fuse and battery, at each voltage
These are the maker’s own figures, at each voltage it is sold at. The cable is the size for the shortest run in the maker’s table. A longer run may need heavier cable, and the wiring calculator works that out for your own boat.
| Voltage | Draw | Maker’s cable | Fuse | Battery | Run limit |

What holds up and what to weigh
Each point names the fact it rests on.
What holds up
- Sleipner sells it for either end, so it can go at the bow or the stern.The maker's listing
- It is sold at 12 V and at 24 V.The maker's and dealers' listings
- Sleipner also prints a second, lower thrust figure for when the battery sags under load: 176 lb at 10.5 V.The maker's published rating
What to weigh
- The boat comes out of the water to fit it: it needs a large hull opening 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 Sleipner SRVP80 PRO, written from the maker’s manual, its product pages and the dealer’s listing.
In the box: Proportional: the joystick sets how hard it pushes. The power controller (PPC) is included.
12 V
This retractable lives in a housing let into the hull through a large opening, and drops when used. It is a bigger yard job than a tunnel. It also has a mechanism to keep in order. The vertical-motor 80 kg retractable with speed control (PRO).
Videos
Two of Sleipner’s own videos, from its YouTube channel: X-Yachts on the ERV100 retractable in a 47 ft sailboat, and how the SRV and SRL retractables go in. 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.
