The short answer. Same electrics as the freshwater Terrova QUEST, longer shafts, salt in the air. 24 V or 36 V, sensed at power-on. Minn Kota’s table: 60 A max draw, a 60 A breaker rated for your voltage, 6 AWG for the first 10 ft of extension. The manual calls the QUEST line “optimized for use with LiFePO4”. Then it tells you to rinse the motor in freshwater every trip, and that goes for the terminals too.
What the salt changes
The battery numbers don’t change. Table D in the Riptide manual is the same one the freshwater QUEST motors print. What changes is where the wire lives. An 87 in or 100 in shaft means a bigger boat, and a bigger boat usually means the batteries are further from the bow. Measure that run before you buy cable; the table below is by length, and the longest Riptide leads are already about 8 to 9 ft of 8 AWG from the factory.
Minn Kota’s saltwater routine, from the maintenance pages: – Rinse the whole motor with freshwater after every use. – Stow it so the steering housing drains. – Keep the battery terminals clean; the manual says sandpaper or emery cloth. – The warranty page adds a hard one: damage from running the motor with water in the lower unit isn’t covered.

Minn Kota’s table (3% drop)
| Bank | Max draw | Breaker | 5 ft | 10 ft | 15 ft | 20 ft | 25 ft |
|---|---|---|---|---|---|---|---|
| 24 V (90 thrust) | 60 A | 60 A, min 24 VDC | 6 | 6 | 4 | 4 | 2 AWG |
| 36 V (115 thrust) | 60 A | 60 A, min 36 VDC | 6 | 6 | 6 | 6 | 4 AWG |
“Minimum 24 VDC” is the breaker’s voltage rating, so a 12 V-rated breaker is out. Minn Kota’s part is the MKR-27 (1865115). Over 25 ft of extension, the manual sends you to a marine technician. For a run in between the columns, the Wire gauge calculator will do the drop math.
Lithium on a Riptide QUEST
The manual’s lithium line is the strongest Minn Kota writes: the QUEST motors are “optimized for use with LiFePO4 lithium-ion battery cells”. Lead-acid still works (flooded, AGM or gel, Group 24 to 31). For lithium, the only rule is for US boats: batteries that meet Coast Guard regulations and ABYC standards, E-13 in particular. No amp-hour number is given, so ours is below.
Our fit rule: match the voltage, and the pack’s continuous discharge must cover the 60 A max draw.
| Pack | For | Ah | Continuous | Salt note |
|---|---|---|---|---|
| Pro-Guide 24VM90 24V 90Ah lithium | 24 V | 90 | 90 A | IP67 case |
| Pro-Guide 24VM115 24V 115Ah lithium | 24 V | 115 | 100 A | IP67, taller |
| Pro-Guide 36VM60 36V 60Ah lithium | 36 V | 60 | 60 A | IP67; meets the draw exactly |
| Pro-Guide 36VM75 36V 75Ah lithium | 36 V | 75 | 75 A | IP67, taller |
IP67 is the pack maker’s rating for the case. It doesn’t make the terminals immune; rinse and keep them clean, as Minn Kota says.
Hours on the water (example)
Same math as the Run time calculator in trolling mode: 80% of the amp hours divided by the amps, warm day.
- 24VM90: 1 h 12 min at 60 A, 2 h 24 min at 30 A.
- 24VM115: 1 h 32 min at 60 A, 3 h 04 min at 30 A.
- 36VM60: 48 min at 60 A, 1 h 36 min at 30 A.
- 36VM75: 1 h 00 min at 60 A, 2 h 00 min at 30 A.
Minn Kota says nothing about hours, and the 60 A figure is the top of the throttle. Holding a spot in current pulses the motor; the average is lower.
Wiring and the warranty
A single 24 V or 36 V pack: positive through the breaker, negative straight to the motor’s black lead. Two or three 12 V batteries: series, with battery #1 as the Low Side. Steps are in Trolling motor battery: 12V, 24V or 36V, wired right.
What the manual ties to the warranty, in its words: alternator charging that connects the trolling-battery negatives to the crank battery’s negative “can damage” the motor’s electrical system, “voiding your warranty”. Radios and sonar don’t go on the trolling bank (“interference from the trolling motor is unavoidable”). Any accessory negative lands on the Low Side battery only, and damage from wrong connections between battery systems isn’t covered.
Charging and storage
Pro-Guide’s 24 V packs charge to 28.8 V and the 36 V packs to 43.2 V. We don’t list a charger at those voltages yet, and no 60 A breaker yet; the MKR-27 is Minn Kota’s. Disconnect the motor while charging. Minn Kota’s lithium note: charge just before you use the pack, and don’t store it full for months. The motor also shuts itself off after 90 minutes stowed.
Quick answers
Does the Riptide Terrova QUEST take lithium? Minn Kota says the QUEST series is optimized for LiFePO4. US buyers: batteries that meet Coast Guard regulations and ABYC E-13.
What breaker for a Riptide Terrova QUEST? 60 A, manual reset, rated at least 24 VDC (24 V bank) or 36 VDC (36 V bank). Minn Kota’s part: MKR-27.
What does Minn Kota say about saltwater care? Rinse the whole motor with freshwater after use, stow it to drain, keep terminals clean. Water in the lower unit voids coverage for that damage.
Can I see the battery on my Minn Kota fish finder? Yes, in 1% steps, after you set the battery chemistry and system type.
