What we can help with

01

Engine and computer diagnostics

Volvo Penta VODIA and Mercury G3 connection diagnostics combine electronic information with on-board inspection. If an alarm appears or engine performance changes, share the engine model, the alarm text and the conditions in which the symptom occurs.

02

Marine electrical work and equipment installation

We support batteries, charging equipment, electrical systems and equipment installation. Tell us which equipment is affected, whether shore power or a generator is in use, and when the problem occurs.

03

Main engines, generators and hull maintenance

Our services include main engine and generator inspections, haul-out, washing, antifouling and work around the hull and propellers. The work needed is discussed after reviewing the vessel’s condition.

04

Lithium batteries, BMS and inverters

We design and configure marine power systems combining lithium batteries, BMS settings, inverters and charging equipment. Share your existing system and how you use power on board.

Quick gyro stabilizers

Our representative completed Quick MC² technical training in Italy. As an authorised dealer, we welcome enquiries about Quick gyro stabilizers.
