Engine Mount Options

Is Your Saildrive Installation Straight Forward?

Beta Marine engines have been fitted into tens of thousands of vessels around the world using our standard engine mounts. We offer a variety of engine mounts to simplify installation for common engine replacements, such as Atomic-4, Perkins 4.108 and various Yanmar models. However engine beds can vary immensely so when a problem arises, our solution is to offer our unique service of designing and manufacturing custom engine mounts to suit your individual engine beds. Your new engine just drops onto your existing engine bearers and lines up with your propeller shaft reducing installation complexity, time and labor.


Simply; click on the drawing highlighted below. An online form will come into view detailing and clarify the information required for your installation. The form can be printed off for reference and used when you next visit your vessel to obtain the necessary data. As a sense check, please always take some photographs of the installation, so these can be uploaded for Beta Marine technicians to refer.

Submitting Your Data

Once you have the required data and supporting photographs revisit this website page, enter your data, upload you photographs and submit your form.

Approving Your Engine Mounts

Once your engine mount form and photographs have been received, Beta Marine technicians will produce a virtual reality 3D model, once they are satisfied it will full fill your installation needs, a 2D drawing will be created and a pdf returned to you. Once this has been received it will need to be carefully checked through, approved and returned to Beta Marine before any manufacturing commences.

Once Approved

Once approval has been received, we manufacture, paint and assemble your engine ready to drop onto your vessels existing engine bearers. Note: Where possible we will fit them directly on to the engine, but if they will not fit within the engine shipping case we will send the mounts loose, using standard mounts to secure the engine for transportation.

Please Note

Should any of the dimensions submitted be incorrect and a re-modelling is required a charge for the additional cost will be made. Beta Marine will not be held responsible for the incorrect fitment of an engine due to incorrect measurements being supplied to us. If you are unsure on which installation is within your vessel or require further clarification, please contact Beta Marine. Whenever one to one assistance is required, it is imperative to have available current installation photographs so we are able to fully understand the installation and be able to provide a solution.

Recommended Measuring Tools

The following tools are recommended to be available to take the required measurements accurately. All measurements are taken from the propeller shaft centreline (the datum).

Flexible Mountings

Are supplied with all our engines as standard. Correctly installed, these will isolate an extremely high percentage of the engine vibration from the vessel and are adjustable for both height and width.

Beta 10 to Beta 45T
Small Flexible Mountings
Beta 43 to Beta 150
Large Flexible Mountings

Engine Pads

If the flexible mountings are wider than your engine bearers, Beta Marine can supply solid mounting pads that fit between the flexible mountings and your engine bearers.
