Rhodan Gen5 GPS Trolling Motor — 36V | 120" Shaft | White
Rhodan Gen5 GPS Trolling Motor — 36V | 120" Shaft | White
Rhodan Gen5 GPS Trolling Motor — 36V | 120" Shaft | White
The Rhodan Gen5 120" White (36V) is the maximum-reach motor in the Gen5 lineup — built for extreme freeboard offshore platforms with a bow height over 60". It delivers 120 lbs of thrust to hold position in the most demanding open ocean conditions: offshore reefs, wrecks, ledges, and structure in wind and tidal current. It carries the same GPS Anchor dynamic positioning system, full-screen base display, and native Simrad, Raymarine, and Lowrance integration as every Gen5 motor.
The white finish blends cleanly with modern offshore boat styling and is particularly popular on large offshore center consoles and charter boats with white gelcoat.
The 120" is a specialty fit. Most boats that believe they need a 120" shaft actually fit a 108". Measure your bow height carefully before ordering.
Available Finishes: ⚫ Black | ⚪ White (Current Model)
Manufactured in Sarasota, Florida with 90% U.S. content. Backed by a 5-year limited warranty with direct access to Rhodan's customer service team.
Is This the Right Model for Your Boat?
| Choose this model if... | Consider another model if... |
|---|---|
| Your bow height is over 60" | Your bow height is under 60" (use 108" shaft or shorter) |
| Your vessel weighs 6,000–15,000 lbs | Your vessel weighs under 6,000 lbs (use 24V) |
| You fish an extreme freeboard offshore or charter platform | You run Garmin electronics and want native helm integration |
| You run Simrad, Raymarine, or Lowrance electronics | You're unsure of your bow height (measure first — most boats fit 108") |
Important: The 120" is the longest shaft in the Gen5 lineup and is a specialty fit. If you're not certain your bow height exceeds 60", the 108" shaft is likely the correct choice. Contact TrollingMotors.shop before ordering.
Why the 120" Shaft? Maximum Reach for Extreme Offshore Applications
The 120" is the top of the Gen5 shaft lineup — the maximum-reach option for the largest, highest-freeboard offshore platforms where no shorter shaft will keep the prop in the water through ocean swell. Each shaft length in the 36V lineup has a distinct role:
- 84" — Entry point into dedicated offshore — purpose-built offshore center consoles (bow 42–48")
- 96" — High-freeboard offshore center consoles (bow 48–54")
- 108" — Large offshore and tournament boats (bow 54–60")
- 120" ← This motor — Maximum reach for extreme offshore applications (bow 60"+)
If your bow height is under 60", the 108" shaft is the correct fit. When in doubt, choose the next longer shaft — but measure carefully, because the 120" is a specialty item that most boats do not require.
Who Should Choose the Rhodan Gen5 36V 120" Shaft?
This motor is ideal for:
- Extreme freeboard offshore platforms with a bow height over 60"
- Very large charter boats and tournament rigs where no shorter shaft will reach the water in swell
- Anglers running Simrad, Raymarine, or Lowrance electronics
- Boats that have already confirmed a 108" shaft is insufficient for their bow height
Excellent for these species and scenarios:
- Snapper · Grouper · Amberjack · Cobia · King Mackerel · Mahi · Tuna · Wahoo · Swordfish · Marlin
- Live-bait fishing over offshore wrecks and reef structure on very large platforms
- Deep-water bottom fishing requiring maximum prop depth in swell
- Tournament offshore fishing on the largest center consoles and charter boats
Who Should NOT Buy This Motor
Don't buy this model if:
- Your bow height is under 60" — the 36V 108" shaft or shorter is the correct fit
- You haven't measured your bow height — most boats that think they need a 120" actually fit a 108"
- Your vessel weighs under 6,000 lbs — a 24V motor is the correct and more cost-effective choice
- You run Garmin electronics and want native helm integration — the Garmin Force Kraken is the correct motor
We'd rather help you find the right motor than sell you the wrong one. Contact TrollingMotors.shop before ordering if you're unsure.
Typical Boats for the 36V 120" Shaft
The following boat types may pair with a 36V 120" shaft. This is not a compatibility guarantee — always confirm your specific bow height before ordering. The 120" is a specialty fit and most boats do not require it.
- 35–45+ ft extreme freeboard offshore center consoles with bow heights over 60"
- Very large charter boats with maximum freeboard
- The largest tournament-rigged offshore platforms
Confirm your bow height measurement before ordering. If you're unsure, contact TrollingMotors.shop — we'll help you confirm the correct shaft length.
Real-World Performance — Where This Motor Works
The 36V Gen5 120" is built for the largest offshore platforms where extreme bow heights demand maximum shaft reach. The 120" shaft keeps the prop in the water on extreme freeboard boats where even a 108" shaft would break the surface in ocean swell and lose all thrust.
Extreme freeboard offshore platforms: The only shaft in the Gen5 lineup that reaches the water on boats with bow heights over 60". GPS Anchor holds position through ocean swell, tidal current, and open ocean wind on the largest platforms.
Deep-water bottom fishing: Lock onto reef edges, wrecks, and bottom transitions in open water. The 120" shaft maintains prop depth through ocean swell where shorter shafts on extreme freeboard boats would break the surface and lose hold.
Tournament and charter fishing: All-day runtime on the largest offshore platforms in demanding open ocean conditions. The 36V system operates with more thrust reserve, drawing less proportional current at typical fishing speeds.
Shaft Selection at a Glance — 36V Series
| Shaft | Best Bow Height | Typical Boat | Best For |
|---|---|---|---|
| 84" | 42–48" | Dedicated offshore center consoles | Entry point into dedicated offshore |
| 96" | 48–54" | High-freeboard offshore center consoles | High-freeboard offshore fit |
| 108" | 54–60" | Large offshore / tournament / charter boats | Large offshore and tournament platforms |
| 120" ← This motor | 60"+ | Extreme freeboard / largest offshore platforms | Maximum reach for extreme offshore applications |
When in doubt, measure your bow height first. Most boats that believe they need a 120" shaft actually fit a 108". Contact TrollingMotors.shop before ordering. → Use Rhodan's official size guide to confirm your selection.
GPS Anchor — Rhodan's Precision Dynamic Positioning System
Rhodan's GPS Anchor uses a dynamic positioning system that continuously calculates and applies thrust corrections to hold your exact GPS position — compensating for wind, current, and wave action in real time. On a 36V system with a 120" shaft, GPS Anchor has the reach to stay in the water through ocean swells on even the most extreme freeboard boats and the thrust reserve to hold position when conditions deteriorate offshore.
Activate GPS Anchor from the wireless FOB remote, the Rhodan app, or directly from the base display. Your position is locked until you release it.
Simrad, Raymarine & Lowrance Integration
The Gen5 supports native integration with compatible Simrad, Raymarine, and Lowrance multifunction displays through Rhodan's supported NMEA 2000 networking and gateway hardware — the Rhodan MFD Gateway and a properly configured NMEA 2000 network.
Important: Integration requires the Rhodan MFD Gateway, a compatible NMEA 2000 backbone, T-connector, and compatible display firmware. Confirm display compatibility and required networking hardware with Rhodan or TrollingMotors.shop before purchase.
If you run Garmin, the Garmin Force Kraken is the correct motor for native Garmin integration.
Rhodan App — Full Motor Control from Your Phone
The Rhodan app (iOS and Android, free) provides full motor control from your smartphone — speed, heading, GPS Anchor, and motor status.

Frequently Asked Questions
Do I really need the 120" shaft?
Only if your bow height exceeds 60". Most boats that believe they need a 120" shaft actually fit a 108". Measure from the mounting surface to the waterline with a typical fishing load. If that measurement is under 60", the 108" shaft is the correct fit. Contact TrollingMotors.shop if you're unsure.
How do I measure my bow height?
Measure from the mounting surface (where the motor base will sit) to the waterline with a typical fishing load. That measurement determines the correct shaft length. Confirm with Rhodan's official size guide or contact TrollingMotors.shop before ordering.
Why do I need 36V instead of 24V?
If your vessel weighs over 6,000 lbs and you fish dedicated offshore conditions, 24V (80 lbs thrust) may not provide sufficient holding power. The 36V system produces 120 lbs of thrust — 50% more — with greater steering authority in open ocean wind and longer runtime for all-day offshore trips.
Does the Gen5 work with Garmin chartplotters?
No — the Gen5 integrates natively with Simrad, Raymarine, and Lowrance via Rhodan's MFD Gateway and NMEA 2000. For Garmin integration, the Garmin Force Kraken is the correct motor.
Is a circuit breaker required?
Yes. Confirm the correct breaker SKU with Rhodan or TrollingMotors.shop before purchasing — do not use SKU A00155, which Rhodan identifies as a Legacy breaker not compatible with the Gen5.
What battery system does the 36V Gen5 require?
Three 12V marine batteries wired in series, or a dedicated 36V lithium battery. Confirm battery capacity with TrollingMotors.shop for your runtime requirements.
Where is the Rhodan Gen5 made?
Sarasota, Florida, using U.S. and globally sourced parts (90% U.S. content).
What warranty does the Gen5 include?
A 5-year limited warranty with direct access to Rhodan's customer service department.
Does the remote come included?
Yes. The Gen5 includes a wireless FOB remote, a Quick Release Bracket, and a RAM Mount Stabilizer.
