Marine Diagnostics

Marine Diagnostics

We are proud to announce we can now carry out computer diagnostics on compatible engines, drives and associated systems.
We are the first to offer JALTEST diagnostics in Europe. The system has proved successful in the US.
Volvo Penta is among the many inboard makes we can connect to. Many other manufacturers of inboard and outboards can be connected.
We can test individual sensors, saving time and money. It takes the “try it and see if works” out of the diagnosis.
We can carry out diagnostics whether the vessel is afloat or ashore.
Feel free to book your diagnostic report on 01481-822772.Read More

Wireless Killcord !
March 2nd, 2014


CoastKey works as a wireless engine kill switch. If the driver falls overboard, the communication between the boat and driver is disrupted, the engine will stop immediately and the signal beacon is activated. In addition the existing killcord can still be used alongside the CoastKey.


CoastKey is a great looking wireless device worn as a pendant around the neck or clipped to clothing. This allows the driver to safely move about on board, without the need to be leashed to the console.


CoastKey also acts as an immobiliser. This is automatically activated when the ignition is switched off.
