About the ezDrive Standard
The Standard is the plain upright version of ezDrive’s transom thruster: the unit bolts flat against the hull with no bracket, 15 in tall and the lightest of the three at 35 lb. It gives 88 lb of push either way on 12 V, so a wake boat can tuck its stern into a tight slip or line up on the trailer. ezDrive comes from the team behind Yacht Thruster and launched in 2018.
There is no published price: ezDrive quotes each boat. In the kit are the iBox, a lit rocker switch, the hardware and a 225 A breaker that also cuts the power off. Plan on heavy battery cable: ezDrive’s guide for its horizontal units insists on at least 1/0 gauge. Add a Group 31 AGM battery if you can fit one; it is suggested, not required. What else you buy.

It goes on through one 1.25 in hole in the transom, sealed with neoprene gaskets and no glass work. ezDrive publishes no guide for its upright models, so get the one from the box to your installer early; its horizontal guide says to install the unit as low as you can, never below the bottom of the hull. Give each push no more than ten minutes. The two-year warranty needs registering, and moving the unit to another boat ends it.
Installers will find the wiring figures and dimensions further down. For the rest of ezDrive’s line, read the Yacht Thruster and ezDrive review.

Will the ezDrive Standard steer your boat?
46 FT TRAWLER · STERN · 15 KT WIND
Every knot figure here is wind speed, not boat speed or current.
On a 46 ft trawler the ezDrive Standard (88 lb) steers her in a 15 knot breeze. Her stern needs about 98 lb from an external unit on the transom to steer her in a 15 knot breeze. Its 88 lb lands within 15 percent of that figure, which this site counts as enough.
The finder leaves it off her list. We found no published price for ezDrive, and the finder lists only units it can price.

Outlined: the finder does not list it at that length (under 13 kt, far more than she needs, or outside ezDrive’s own length range).
- Under 10 kt
- 10 to 15 kt
- 15 to 20 kt: the sweet spot
- Over 20 kt: more than she needs
Prices are the low end of the installed total, from our estimate. For your own boat, drive and installer, the finder prices each unit.
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 |
|---|---|---|
| Pontoon & tritoon | Not listed. Its maker does not name this kind of hull. | |
| Sailboat | 32 to 45 ft | 46 to 51 ftfull thrust to about 13 knots at 51 ft |
| Houseboat | Not listed. Its maker does not name this kind of hull. | |
| Catamaran | Not listed. An external unit bolts to the side of a single hull at the bow or to its transom, and a cat has two narrow hulls with a bridgedeck between them, so there is nowhere forward to hang one. | |
| Trawler | 31 to 44 ft | 45 to 51 ftfull thrust to about 13 knots at 51 ft |
| Motor yacht | 35 to 44 ft | 45 to 51 ftfull thrust to about 13 knots at 51 ft |
| Bass & flats | No length. More thrust than the boat needs. | |
| Wake & ski boats | No length. More thrust than the boat needs. | |
| Express cruiser | 40 to 57 ft | 58 to 65 ftfull thrust to about 13 knots at 65 ft |
| Center console | No length. More thrust than the boat needs. | |
The ezDrive Standard 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 trawler gets full thrust to 44 ft, and an express cruiser to 57 ft.
The table tries the ezDrive Standard 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 where it mounts. ezDrive publishes no boat length, so thrust alone decides.
It is sized for four 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
No US dollar price is published for the ezDrive Standard, so we build no total for it. The yard’s share of the job is on the cost page.
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.
DIY breakdown
DIY levels
- Level 5: Owner install. No yard, no electrician.
- Level 4: You install 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 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
- Mount the thruster at the transom; fit the battery and control box; run the cables You 8 to 16 hours Our estimate. ezDrive prints no time; one owner reported about 10 hours, and the range is widened for a first install. Source.
- 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.

Charger: a NOCO GEN5X2 two-bank shore charger, $146.41. It is the one our estimate prices.
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 1.25 in stainless steel threaded thru-hull fitting through the transom; position not stated relative to the waterline.
ezDrive publishes no boat length for it. The boat table is our sizing alone.
No US dollar price is published for it, so we can work out no installed cost.

For the install what the box leaves you to buy
From ezDrive’s FAQ and installation page, read 13 October 2026.
- In the box
- The thruster, mounting hardware, the iBox with its communication cable, the lit rocker control and the power flow nozzles, which the FAQ lists for every ezDrive kit. The protection is a 225 A breaker with quick shut-off, named on ezDrive's specification page.
- Bought separately
- The battery cable. The installation page says the package holds every part a normal install needs except the battery cables. ezDrive publishes no installation guide for this model. Its guide for the horizontal units asks for 1/0 AWG cable at least.
- Charging
- It runs off a 12 V battery, and ezDrive suggests a Group 31 AGM of its own. It says nothing about a charger.
In ezDrive’s words, from the FAQ: “Although a dedicated battery is not required, it is recommended for best performance. (Suggested: Group 31 AGM)”
A yard job adds these parts on top of the unit: $8 to $12 for the priced ones, at Fisheries Supply’s prices on 26 October 2026, plus the batteries, cable and charger. The cost page has what every maker says about each part.
Control-circuit fuse holder
Fisheries Supply lists it as “Waterproof in-line ATO/ATC fuse holder”.
ezDrive asks for a 5 A in-line fuse only with the joystick or throttle option; the rocker needs none.
Batteries
Fisheries Supply lists it as “Optima BlueTop SC31DM Group 31 AGM”.
One Group 31 AGM, the maker’s suggestion. The cheapest listing of that group and type.
Battery cable, red and black
Defender lists it as “Ancor tinned battery cable 1/0 AWG, cut to length, red or black”.
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, 1/0 AWG, bag of 10”.
The listing runs $23.74 to $28.04 by stud size. Eight ends on one run, with two spare.
Charger
Fisheries Supply lists it as “GEN5X2 on-board charger, 10 A, 2 banks”.
Or a DC-to-DC charger from the house system: ask the electrician.
No part matches. Try the number without spaces, or the part’s name.

Our note
Mounted flat against the hull with no stand-off bracket: 15 in tall, 35 lb. A 12 V transom unit for wake and ski boats, through one 1.25 in threaded fitting in the transom. ezDrive rates it 88 lb at 12 V and 77 lb at 10 V, and it draws 245 A.
It runs up to ten minutes, with a confirm-to-continue at three and a quarter minutes. ezDrive does not say whether it can be installed afloat. No price is published. The maker quotes by email. A dedicated Group 31 AGM battery is recommended, not required.
