SeaProp 60

The Beta Marine replacement engine and saildrive solution comprises of an appropriate new engine of choice fitted with a shallow sump mated to a Technodrive SeaProp 60 saildrive. Which when used in combination with our special feet option will drop into your existing Volvo or Yanmar saildrive GRP moulding.

Note: Replacing a Bukh saildrive leg will required the fitting of the Beta Marine optional GRP moulding as direct replacement to the existing mould.

The SeaProp 60 can accommodate a clockwise or anti-clockwise output rotation and is available in a reduction ratio of 2.15:1 or 2.38:1. Additionally, should your vessels hull design require it, the saildrive leg can be turned through 180 degrees so that the engine is directly over the propeller.

The Engine and SeaProp 60 package includes engine with shallow sump, housing to mate with the Seaprop 60 mounting bracket, through the hull fitting twin diaphragm seal and engine fresh water cooling valve. The transmission main structure is made of die-cast aluminium alloy, hardened and treated against corrosion. Additional protection against galvanic corrosion is guaranteed by sacrificial zinc anodes. The Engine and Seaprop 60 are not mated at the factory and shipped together, independently packed.

Adaptor Kit Options & Technical Drawings

Beta Marine offer the following gearbox options and reduction ratios. We have selected suitable gearboxes to match the torque loading of each engine, and this will be correct for the majority of yachtsmen and canalboat owners. Some customers, such as commercial fishermen, may require a heavy duty gearbox and/or different reduction ratios to suit their heavy duty requirements. We can also mount your old/existing gearbox on a new Beta engine, if you wish to send it to us. Find out more…

Shallow Sump

For vessels with very limited space between the engine, bearers and hull we can offer a specially designed shallow sump option, standard on saildrives. The key differences are a reshaped sump pan and repositioning of the sump pump connection.

Oil volumes are marginally reduced (please refer to relevant operators manual) but the dip stick calibration is unchanged. However when this option is fitted, it is important to note that the frequency of the oil change period is reduced. Rather than the standard oil change hours of use, engines fitted with a shallow sump require an initial change after 50 hours then either annually or every 150 hours if sooner.

Special Feet Service

Beta Marine engines have been fitted into tens of thousands of vessels around the world using our standard engine feet. However engine bearers can vary immensely so when a problem arises, our solution is to offer our unique service of designing and manufacturing ‘Special Engine Feet’ to suit your individual engine bearers.

Having designed, manufactured & supplied thousands of bespoke ‘Special Feet’ when required, the additional cost of this option is heavily repaid when your new engine just drops onto your existing engine bearers and lines up with your propeller shaft reducing installation complexity, time and labour.
