About the Max Power CT125 stern pod

The CT125 stern pod is the 24 V partner to the CT100 pod: 254 lb of push at the stern for boats of about 34 to 59 ft, from twin propellers in a pod bolted to the outside of the transom.

It costs $4,913 at Marinedeal. You add a control panel, a main switch, a fuse and a fuse holder, about $307 to $642, and two batteries in series near the stern with their cable and charger, about $961 to $1,180. The full parts list.

On 24 V it draws far less current than the 12 V CT100 pod. Before you bolt it on, check that the transom is flat and strong; Max Power says to flatten and stiffen it if not. Keep pushes under 3 minutes. Warranty: three years, transferable.

Will the Max Power CT125 stern pod steer your boat?

64 FT TRAWLER · STERN · 15 KT WIND

Size forThis page always opens on Steering.

Every knot figure here is wind speed, not boat speed or current.

Steers her at 18 kt

On a 64 ft trawler the Max Power CT125 stern pod (254 lb) steers her in an 18 knot breeze. Her stern needs about 193 lb from an external unit on the transom to steer her in a 15 knot breeze.

The finder lists it for her.

The Max Power CT125 stern pod 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 every kind of boat it fits gets full thrust to 64 ft. The maker gives one range for every boat.

The table tries the Max Power CT125 stern pod 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 64 ft, just past Max Power’s own range (34 to 59 ft).

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 installing. The compare page sets this unit beside others.

What it costs installed

A yard job, everything in. Our estimate.

Installed by a yard
Boat Total installed
53 ft $8,501 to $12,895$33 to $51 a lb of thrust
60 ft $8,621 to $13,235$34 to $52 a lb of thrust
64 ft $8,691 to $13,425$34 to $53 a lb of thrust

From the shortest to the longest boat it is sized for.

What is in each total five lines

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 $1,040 to $3,090 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.

Each line of the estimate
Boat length The unit Yard labor Haul-out Batteries, cable, charger Other parts
53 ft $4,913 $1,280 to $3,6008 to 20 hours $1,040 to $2,560 $961 to $1,180 $307 to $642

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 800 CCA each (Max Power’s minimum), $720 for both; Max Power’s cable table gives 1/0 to 3/0 AWG, priced on 1/0 to 4/0 AWG, the nearest size cut to length: $95 to $314 for the red and black cable and the lugs; a GEN5X2 charger, $146.

  2. 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.

A qualified marine electrician should make the final connections and test them before first use. Hours are labor only.

For the install what the box leaves you to buy

10 parts

The manual button above opens it on the maker's site. It has the hull, wiring and fuse figures for this model.

From Max Power’s Stern Pod installation manual, read 16 October 2026.

In the box
The pod alone. The manual says it is delivered without the fuse, the fuse holder or a control panel.
Bought separately
The fuse and its holder, the control panel, the battery isolators, the 8 A control fuse and its breaker, the battery cable, the batteries, the screws and the sealant.
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.

In Max Power’s words, from its CT100 and CT125 installation manual, 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 covers these parts as a range, $307 to $642 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.

Control panel

Ask for Max Power control panel (joystick or red/green push-button type).

No part number is printed for it. A Max Power dealer can give you the one that suits this model.

Fuse holder

Part number 2306

Control-circuit fuse holder

Fisheries Supply lists it as “Waterproof in-line ATO/ATC fuse holder”.

The maker asks for an 8 A fuse on the control supply.

Part number 5065

Batteries

Fisheries Supply lists it as “Optima BlueTop SC27DM Group 27 AGM”.

You need 2, each at 800 CCA or more, in series for 24 V. The cheapest listing that meets it.

Part number BAT SC27DM

Battery cable, red and black

Defender lists it as “Ancor tinned battery cable 1/0 AWG, cut to length, red or black”.

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.

Part number None on the listing. Order it by name.

Cable lugs

Fisheries Supply lists it as “Tin-plated starter lugs, 1/0 AWG, bag of 10”.

This is the short run. A longer run takes heavier cable: the wiring calculator sizes yours. The listing runs $23.74 to $28.04 by stud size. Eight ends on one run, with two spare.

Part number 91066-P10

Charger

Fisheries Supply lists it as “GEN5X2 on-board charger, 10 A, 2 banks”.

Our notes from the manual and listings

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 install it. The January 2010 pod manual gives it 389 A at 24 V. 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.
