Rhodan Gen5 GPS Trolling Motor — 36V | 84" Shaft | Black
The Rhodan Gen5 84" Black (36V) is the entry point into Rhodan's dedicated offshore lineup — the first shaft length purpose-built for dedicated offshore center consoles rather than crossover bay boats. It's the correct fit for boats with a bow height between 42" and 48", delivering 120 lbs of thrust to hold position in the most demanding saltwater environments: open ocean, offshore reefs, wrecks, 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.
Available Finishes: ⚫ Black (Current Model) | ⚪ White
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 between 42" and 48" | Your bow height is under 42" (use 72" shaft or shorter) |
| Your vessel weighs 6,000–15,000 lbs | Your bow height is over 48" (use 96" shaft) |
| You fish a dedicated offshore center console | Your vessel weighs under 6,000 lbs (use 24V) |
| You run Simrad, Raymarine, or Lowrance electronics | You run Garmin electronics and want native helm integration |
Why the 84" Shaft? The Entry Point Into Dedicated Offshore
The 84" is where the Gen5 lineup transitions from crossover boats into purpose-built offshore platforms. Each shaft length in the 36V lineup has a distinct role:
- 48" — Maximum thrust for lower-bow offshore boats (bow under 30")
- 60" — The versatile sweet spot for offshore bay boats and mid-size center consoles (bow 30–36")
- 72" — The offshore crossover — higher bows and rougher conditions (bow 36–42")
- 84" ← This motor — Entry point into dedicated offshore — purpose-built offshore center consoles (bow 42–48")
- 96" — High-freeboard offshore boats and tournament platforms (bow 48–54")
- 108" — Charter boats and very high bows (bow 54–60")
- 120" — Maximum reach for extreme offshore applications (bow 60"+)
If your bow height is under 42", the 72" shaft is the correct fit. If your bow height is over 48", step up to the 96" shaft. When in doubt, choose the next longer shaft — offshore conditions are less forgiving than inshore.
Why Choose 36V Instead of 24V?
The 36V Gen5 produces 120 lbs of thrust — 50% more than the 24V. That difference is not about speed. It's about holding power under load, steering authority in wind, and runtime when the motor is working hard.
Choose the 36V Rhodan Gen5 if you:
- Fish a dedicated offshore center console over 6,000 lbs
- Regularly fish in strong tidal current, rough inlets, and open ocean conditions
- Fish offshore reefs, wrecks, and live bottom where GPS Anchor hold is critical
- Need maximum steering authority in wind and chop
- Want additional thrust reserves for all-day offshore use
- Fish in conditions where a 24V motor would be working at or near its limit
Who Should Choose the Rhodan Gen5 36V 84" Shaft?
This motor is ideal for:
- Dedicated offshore center consoles between 6,000 and 15,000 lbs with a bow height of 42–48"
- Anglers fishing offshore reefs, wrecks, ledges, and live bottom
- Boats that need sustained GPS Anchor hold in open ocean wind and current
- Tournament anglers requiring all-day offshore runtime
- Anglers running Simrad, Raymarine, or Lowrance electronics
Excellent for these species and scenarios:
- Snapper · Grouper · Amberjack · Cobia · King Mackerel · Mahi · Tuna
- Live-bait fishing over offshore wrecks and reef structure
- Snapper and grouper on deep bottom structure
- Reef edges and bluewater bait schools
- Offshore ledge and drop-off fishing
- Maintaining position in ocean swell over live bottom
- Tournament offshore fishing requiring all-day runtime
Who Should NOT Buy This Motor
Don't buy this model if:
- Your bow height is under 42" — the 36V 72" shaft or shorter is the correct fit
- Your bow height is over 48" — step up to the 36V 96" shaft
- 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 if you're unsure.

Real-World Performance — Where This Motor Works
The 36V Gen5 84" is built for open ocean conditions where GPS Anchor hold is most critical and where shaft reach matters as much as thrust. On a dedicated offshore center console with a high bow, the 84" shaft keeps the prop in the water through ocean swells and chop — maintaining GPS Anchor hold when shorter shafts would break the surface and lose all thrust.
Offshore reefs and live bottom: Hold position precisely over structure in tidal flow and open ocean wind. The 36V system maintains GPS Anchor hold when conditions build — keeping you on target over the exact piece of structure you're fishing.
Live-bait fishing over offshore wrecks: Stay positioned over structure while working live bait in current and wind. GPS Anchor holds through tidal changes, keeping your bait in the strike zone without constant repositioning.
Snapper and grouper on deep structure: Lock onto reef edges, rock piles, and bottom transitions in open water. The 84" shaft stays in the water through ocean swell where shorter shafts on high-bow boats would break the surface and lose hold.
Reef edges and bluewater bait schools: Work color changes and bait concentrations in open water where wind and current combine. Extended runtime under load keeps you fishing longer without worrying about battery reserves.
Offshore ledges and bottom transitions: Maintain position over ledges and drop-offs in open water. The 36V system has the thrust reserve to hold through current changes and wind shifts that push lighter motors off target.
Tournament offshore fishing: All-day runtime under demanding open ocean conditions. The 36V system operates with more thrust reserve, drawing less proportional current at typical fishing speeds — critical for full-day offshore trips.
Wind-against-tide situations: Maintain station when wind and current are working against each other in open water — the conditions where a 24V motor or shorter shaft would be working at or near its limit.
Shaft Selection at a Glance — 36V Series
| Shaft | Best Bow Height | Typical Boat | Best For |
|---|---|---|---|
| 48" | Under 30" | Low-bow offshore center consoles | Maximum thrust, lightest 36V option |
| 60" | 30–36" | Offshore bay boats, mid-size center consoles | Versatile sweet spot — most common 36V fit |
| 72" | 36–42" | Large bay boats, higher-bow center consoles | Offshore crossover — higher bows and rougher conditions |
| 84" ← This motor | 42–48" | Dedicated offshore center consoles | Entry point into dedicated offshore |
| 96" | 48–54" | High-freeboard offshore boats | High-freeboard offshore and tournament platforms |
| 108" | 54–60" | Large offshore / charter boats | Charter boats and very high bows |
| 120" | 60"+ | Extreme offshore / maximum freeboard | Maximum reach for extreme offshore applications |
When in doubt, choose the next longer shaft. Offshore conditions are less forgiving than inshore — a prop that breaks the surface in chop loses all thrust instantly. → 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 an 84" shaft, GPS Anchor has both the reach to stay in the water through ocean swells 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
Why is the 84" called the entry point into dedicated offshore?
The 84" is the first shaft length in the Gen5 lineup purpose-built for dedicated offshore center consoles rather than crossover bay boats. The 72" serves the offshore crossover market — larger bay boats and hybrid offshore boats with bow heights of 36–42". The 84" steps into a different category: boats with bow heights of 42–48" that are designed specifically for open ocean fishing.
Why do I need the 84" instead of the 72"?
If your bow height is between 42" and 48", the 84" is the correct fit. The 72" is designed for bow heights of 36–42". On a higher-bow dedicated offshore center console, a 72" shaft may not reach the water properly — especially in ocean swells. When in doubt, choose the next longer shaft.
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.
