Max Power CT80 stern pod (24 V): specs, price and boat fit
This is the 24 V CT80 stern pod: 165 lb of push from a pod bolted to the outside of the transom, for boats of about 28 to 46 ft with a 24 V system. It avoids cutting a tunnel through the stern, though the boat still comes out of the water to fit it.
Marinedeal sells it for $3,684, and the 12 V pod is $4,299. On top come a panel, a main switch, a fuse and holder, about $307 to $642, and two batteries in series near the stern with cable and charging, about $946 to $1,037. See every part.
At 24 V it draws about half the current of the 12 V pod, so the cable can be lighter for the same run. Set it one tunnel width below the waterline and clear of trim tabs. The pod manual rates it for 3 minutes at a time. Max Power’s pod warranty runs three years.
Installers will find the wiring figures and dimensions further down. For the rest of Max Power’s line, read the Max Power thruster 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: 4 to 8 h Electrician: 2 to 4 h Plus a haul-out.
- Drill, seal and bolt the unit below the waterline Yard 4 to 8 h Our estimate. No maker times it; one owner paid his yard about a day of labor to mount two units. Source.
- 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.

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 every kind of boat it fits gets full thrust to 50 ft. The maker gives one range for every boat.
The table below tries the Max Power CT80 stern pod (24 V) 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 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 50 ft, just past Max Power’s own range (28 to 46 ft).
| 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 | 43 to 50 ft | None |
| 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 | 43 to 50 ft | None |
| Motor yacht | 43 to 50 ft | None |
| Bass & flats | No length. More thrust than the boat needs. | |
| Wake & ski boats | No length. More thrust than the boat needs. | |
| Express cruiser | No length. More thrust than the boat needs. | |
| 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 three 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 $770 to $2,410 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.
| Boat length | The unit | Yard labor | Haul-out | Batteries, cable, charger | Other parts | Total |
|---|---|---|---|---|---|---|
| 43 ft | $3,684 | $1,280 to $3,6008 to 20 hours | $770 to $2,070 | $946 to $1,037 | $307 to $642 | $6,987 to $11,033 |
| 45 ft | $3,684 | $1,280 to $3,6008 to 20 hours | $800 to $2,170 | $946 to $1,037 | $307 to $642 | $7,017 to $11,133 |
| 50 ft | $3,684 | $1,280 to $3,6008 to 20 hours | $990 to $2,410 | $946 to $1,037 | $307 to $642 | $7,207 to $11,373 |
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 24 V: two 12 V batteries in series, at least 800 CCA each (Max Power’s minimum), $720 for both; Max Power’s cable table gives 1 to 1/0 AWG: $80 to $171 for the red and black cable and the lugs; a GEN5X2 charger, $146.

What else you buy
What follows comes from Max Power’s CT100 and CT125 installation manual, July 2024, read 30 September 2026. That manual is written for the tunnel units. An external unit has no tunnel to buy.
- In the box
- The motor with its relay, the electronic controller, the composite leg with screws and gasket, two propellers. "The thruster is delivered without accessories (fuse, fuse holder, control panel)."
- Bought separately
- The fuse and holder, a manual battery isolator and an electric one, the control panel, an 8 A control fuse, a breaker on the DC panel and the battery cable.
- Charging
- Max Power is the one maker that asks for both: the engine's alternator and a charger. A dedicated bank is optional and goes "as close as possible to the thruster". It wants starting-type batteries with high cold cranking amps.
The manual’s words, page 3: “The batteries used by the thruster must be charged by both the main engine's alternator and an appropriate battery charger.”
The “other parts” line in the estimate above is the priced parts below, $307 to $642 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 |
|---|---|---|---|---|---|
| 24 V | 240 Anominal draw | 1 AWG for up to 16 ft of cable counted out and back. Longer runs take heavier cablestern pod installation manual | Not published | Maintenance-free "starting" type batteries, with high CCA outputs.

What the manual and listings say
This is the note we keep on the Max Power CT80 stern pod (24 V), written from the maker’s manual, its product pages and the dealer’s listing.
In the box: Delivered without accessories: the fuse, holder and control panel are bought.
Our note
A pod bolted to the outside of the hull at the stern, so nothing is cut through the hull. The boat still comes out of the water to fit it. The 24 V version is rated 75 kg where the 12 V one gets 69. The January 2010 pod manual gives it 240 A. Standard on/off units are made for lead-acid, AGM or gel batteries.
Max Power's FAQ says lithium will damage them unless specified correctly. Max Power publishes no price and sells through dealers. The figure here is one US dealer's listing for the unit alone.
