Side-Power SEP100 PRO™ IP tunnel bow/stern thruster 12V

About this product

SEP100 PRO™ IP tunnel bow/stern thruster 12V — 100kg of thrust (116kg at 12V), sized by Sleipner for boats of 12-17m (39-56ft). PRO™ version with proportional speed control, ignition protected for petrol boats and wet stern installations. Fits a 185 mm tunnel and can be installed in the bow or, with a Sleipner stern tunnel, at the stern.

What you get, and what to order with it

This is the thruster unit: motor, gear leg, twin propellers, motor bracket and electronics. To complete a new installation you also need a 185 mm tunnel (GRP, aluminium or steel to suit the hull), a control panel, an ANL 500 fuse and holder, and battery cable sized to the run. The matching items are listed under “You may also need” below, and we will check the whole kit against your boat before it ships.

Features

• Variable speed control — proportional thrust from the joystick, quieter and easier to dock with
• Hold function — with a bow and stern pair, pins the boat to the pontoon while you handle lines
• Ignition protected (ISO 8846) — sealed electrics for petrol boats and stern installations that may get wet
• Intelligent Power Control (IPC) — minimal delay on direction change to reduce wear, with solenoid monitoring that stops the thruster automatically if a contact locks in
• Q-Prop™ five-blade skewed propeller — Sleipner measure up to 75% less noise than a conventional propeller
• Galvanic separation between motor and gear leg to protect against stray-current corrosion
• Overheat protection — shuts down (on/off models) or derates (PRO models) before the motor is damaged
• Ceramic shaft seals and sealed drive lubrication — no oil feed to plumb
• Flexible installation — mounts at any angle on the tunnel; the motor can be turned 90° on the bracket
• S-Link CAN-bus control — plug-and-play signal cables to S-Link panels and joystick systems

Power and battery

Draws 740A at 12 V for a 2–3 minute duty cycle. Sleipner specify a battery of at least 1320 CCA (EN) close to the thruster and an ANL 500 fuse. If the thruster battery is more than a few metres from the unit, size the cable with our battery bank and cable size calculator, and use the thruster size calculator to confirm SEP100 is the right size for your boat.
