Issues at Sea
Regular maintenance of engines and following service schedules are of paramount importance on any craft, wherever you sail. When you head out to sea it's even more important as a breakdown may well not just endanger your own life but risk the lives of your rescuers.

The Nannidiesel Hybrid System
The Nannidiesel Hybrid System, which was launched in September 2009 combines with a diesel engine of up to 200hp and has been tested since 2007 to ensure that it can be easily and securely fitted, either intially or as a later option.
The Hybrid System is based on the principles of a generator. The ...
Preparation for the new season
After experiencing the very cold snap this winter, it will be necessary to pay extra attention to your boat, in particular the engine when preparing for the new season.
Firstly check the water level in the header tank. It should be 3/4 inch from the top. If it isn't, replenish ...
Winter Maintenance
It's the ideal time of year, with the London Boat Show upon us, to think about winter maintenance and servicing. Correct preparation will ensure a successful boating season, and involves several different areas:-
Hull Condition
If your boat is out of the water, it is an ideal to check ...
The Principles behind the Insert Generator
With today's demands for onboard electrical power, both DC and AC becoming more popular, Nanni Diesel has developed an innovative new concept to add to it's already comprehensive range of marine engines.
It's that time of year again when the nights are drawing in and the temperature is cooling off and it is time to start thinking about preparing your boat for storage during the winter months. 'Winterising' an engine is a key maintenance task for any boat owner. Failure to do so ...
Nanni Diesel now offers three new marine engines, 165, 180 & 200hp, based on common rail Toyota blocks from their rugged 4x4 automotive sector. The common rail system used high-pressurised fuel for improved fuel economy and provides robust engine power, while reducing noise and vibration.
Liquid flow rate and pressure are the basic measures of pump performance. Flow rate is commonly measured in litres per second, per minute or per hour or sometimes in cubic metres per hour. Pressure is commonly ...
The circulation of the lubricating oil around the engine has quite rightly been likened to the human blood circulation system. The oil is pumped from the sump through the filter and into the bore holes leading to the main bearings on the crankshaft. After leaving these main bearings, the oil flow is divided. ...
Turn your engine's waste heat into useful domestic hot water with a C-Warm Calorifier. Made in the UK and fitted as standard by leading UK and European boat builders, C-Warm heaters are designed for use at system pressure up to 3 bar (44 psi). Maximum ...
With the introduction of higher output alternators and electronic charge Xsplitters charging systems on boats have vastly improved. To benefit fully from a decrease in recharge time and longer runtime the correct battery choice should be made. When making a battery purchase you need to consider - Battery life ...
Temperature Gauge Problems
Marine engines traditionally have been coupled directly to the propeller drive shaft, perhaps with a stiff flexible coupling between the two. Most of the vibration is sent straight down the shaft, and the engine mounts can't so their job properly because they are strained forwards by propeller thrust. So, vibration gets into the hull, ...
Starter batteries and supply batteries are designed for different tasks. Starter batteries, in order to start the engine, must initially supply a high current level and will then serve as an energy buffer with smaller partial cycles. Supply or domestic batteries, by contrast, are charged at lower current levels for ...
If you haven’t done before, now is an ideal time to start thinking about your boat fuel efficiency. Not only because of the current economic climate and rising fuel prices but also because it can go a small way into helping the environment too.
Alarms instantly if the Sea Strainer blocks..... Why?
Tunnel systems provide a simple cost-effective solution and can be installed at two thirds their diameter below water level. To achieve optimum performance and reduce the risk of damage from surface debris, an immersion depth of one complete tunnel diameter is advised. The longer your tunnel, the ...
With Spring just around the corner, its time to start preparing your boat ready for the season. Whether your boat has been winterised or stored throughout the winter months, there are a few things that you should ensure you do prior to using the boat once again.
The ManeCraft seal comprises of two main components. The stationary seal assembly and the rotating seal assembly, both moulded from tough, oil resistant chloroprene. The stationary seat has a solid bronze ring bonded into it and is clamped onto the stern tube with two stainless clips, ...
