Side-Power SE20 tunnel bow thruster 12V

About this product

SE20 tunnel bow thruster 12V — 20kg of thrust (25kg at 12V), sized by Sleipner for boats of < 7m (< 23ft). Standard on/off version. Fits a 110 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, single propeller, motor bracket and electronics. To complete a new installation you also need a 110 mm tunnel (GRP, aluminium or steel to suit the hull), a control panel, an ANL 150 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

• 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

Power and battery

Draws 150A at 12 V for a 2–3 minute duty cycle. Sleipner specify a battery of at least 330 CCA (EN) close to the thruster and an ANL 150 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 SE20 is the right size for your boat.
