GEARBOXES / SURFACE DRIVES / STEERING / CONTROLS

ENGINE
TO WATER.
ALL OF IT.

HUNTER Boatworks treats the driveline as a system: engine torque, transmission, reduction, couplings, shafts or surface drives, steering, controls and propeller have to agree with the hull and duty cycle.

01 / PERFORMANCE PROPULSION

ARNESON
SURFACE DRIVES.

Twin Disc’s current Arneson family contains seven model sizes, ASD08 through ASD16. Published family torque figures are useful for orientation only; application engineering controls final model and variant selection.

Shaft / family note
2.0 in nominal shaft
Steering / trim
40° steering / 15° trim

Surface-piercing propulsion with hydraulic trim/steering. Exact variant, gearbox adapter, driveline, propeller and installation engineering are project-specific.

02 / MARINE TRANSMISSIONS

TWIN DISC.

Twin Disc publishes more than 100 marine transmission models, so HUNTER uses the manufacturer selector instead of pretending a partial web list is complete.

QUICKSHIFT

MGX transmissions

Integrated transmission/clutch/control families covering down-angle, vertical-offset, V-drive and other arrangements.

  • Current published examples span roughly 500 hp-class through 2,100 hp pleasure ratings.
  • Duty ratings differ materially between pleasure, light, medium and continuous service.
  • Ratio and installation geometry are selected with vessel and propeller data.
QuickShift family ↗
STANDARD

MG transmissions

Traditional Twin Disc marine transmission families for a wide spread of pleasure and commercial propulsion applications.

  • Multiple ratios and housing arrangements
  • Commercial-duty service classes
  • Parts, rebuild and global support network
Transmission selector ↗
ELECTRIC + HYBRID

MGE / MGH

Electric and hybrid transmission families sit alongside Twin Disc’s conventional gears, control systems and propulsion products.

  • project-specific electric/hybrid integration
  • controls and driveline engineering
  • factory selection required

03 / COMPLETE PROPULSION SYSTEMS

ZF MARINE.

ZF’s marine portfolio extends beyond gearboxes into controls, steering, thrusters, propellers and hybrid/complete driveline work. For cruising craft, ZF publishes transmission options for multiple configurations up to 1,500 hp; commercial and fast-craft ranges extend beyond that.

PLEASURE CRAFT

Cruising + sportfish

Vertical offset, down-angle, coaxial and V-drive transmission arrangements with electronic control-system options.

ZF cruising portfolio ↗
COMMERCIAL

Working vessels

ZF supports commercial transmissions, controls, propulsion systems and aftermarket service for repower/new-build applications.

AFTERMARKET

Parts + service

ZF Aftermarket supports marine transmissions, thrusters and control systems with diagnostics, spare parts, repair, overhaul and repower support.

HUNTER BOATWORKS / APPLICATION INTAKE

DON'T ASK
“WHAT GEAR?”
WITHOUT THE BOAT.

For any driveline quote we need the engine and vessel context before a model number means anything.

PREPARE A DRIVELINE ENQUIRY ↗
  1. Boat make/model/year, hull, LOA, beam and loaded displacement.
  2. Engine model, horsepower, rated rpm and torque data.
  3. Pleasure/light/medium/continuous duty and annual hours.
  4. Existing reduction ratio, shaft/drive geometry and propeller data.
  5. Target speed, cruise, maneuvering and installation constraints.
  6. Factory application review before final specification.
