LIFTING THE ENGINE: REVIEW OF POSSIBLE OPTIONS FOR MARINE ENGINE MOUNT REPLACEMENT.
Multiple ways to lift the marine engine at a glance Introduction In order to avoid the tedious process of dismantling numerous components to lift the motor using a halyard or hoist, sailboat owners typically seek innovative solutions to raise it slightly without causing damage to the oil pan. This article will explore various alternatives for […]
HOW TO IMPROVE ENGINE STABILITY
HOW TO IMPROVE ENGINE STABILITY On recreational boats or sailboats, achieving maximum engine stability is often a challenge. There are different factors that must be taken into account: 01. Condition / Performance of the engine 02. Condition of the shaft. Ensure that it is not damaged 03. Condition of the cutless bearing 04. Alignment of […]
WHEN AND WHY SHOULD MARINE ENGINE MOUNTS BE REPLACED?
The main goal of the marine engine mounts is to isolate the vibration generated by the engine and to absorb shocks / vibration when the vessel is cruising. The elastic properties of the marine engine mounts are essential to the prevention of engine damage and to improve the comfort of the boat’s passengers. Must these products be […]
ENGINE BED FLATNESS AND CORRECT PROCESS FOR ALIGNMENT
SOME ADVICE ON THE ENGINE BED CONSTRUCTION. Engine beds are a critical element on for the stability and vibration level of the engine.When determining the engine bed dimensions, full consideration must be given to the stress caused by the propeller’s propulsion and reaction force, the engine’s torque and boat cruising. It is interesting to have […]
CORRECTING PROPSHAFT OFFSET USING THE SLOTTED HOLES OF THE ENGINE MOUNTS
Picture of a propeller shaft directly fixed to the transmission. Sailboat: Jeanneau Sun Odyssey 40.3 2006. Moored in Port Campello, Alicante (Spain), Yanmar 4JH4E, 2 ELLEBOGEN 150 (Ref. 121370-08351) and 2 ELLEBOGEN 200 (Ref. 129470-08350) Propeller shaft is fixed to the marine engine transmission. For obvious reasons, we are interested in the fixation being straight, […]

ENGINE BRACKET FLATNESS INFLUENCE ON VIBRATION ISOLATION
Deformed Engine bracket (left). Engine mount conically inclined (right). Information about the correct installation of flexible engine mounts in marine engines. The flexible engine mounts in marine engines act as springs. They have to work without conical, torsional or twist pre-stress. The hole of the engine brackets and stud of the flexible engine mount should […]
HOW DO THE MARINE ENGINE MOUNTS LOSE THEIR ELASTIC PROPERTIES
This article is associated to a precedent article that deals about the symptoms of how to detect when an flexible engine mount of a marine engine has to be replaced. On this article we are putting more weight on the reasons and process of degradation of the elastomeric compound in marine engine mounts. Knowing how and […]
WHY IS IMPORTANT NOT TO ABUSE ON THE LEVELLING OF THE MARINE ENGINE MOUNTS
This article concerns specifically the users of boats that do not have a thrust bearing in their boat. This is to say, when the thrust of the propeller “pushes” the engine through the anti vibration mounts. In this case the marine engine mounts have to push the boat and resist the thrust forces of the […]
WHY IT IS IMPORTANT TO WAIT 48h BETWEEN FITTING THE NEW MOUNTS AND FITTING THE PROP SHAFT
Due to the several questions from Ellebogen users, we make an article to explain the reasons why the propeller shaft has to be fixed 48 hours after the installation of the marine engine mounts. Vibrations on a marine engine can occur for several reasons or origins, engine unbalance, incorrect stiffness of flexible engine mounts, wear […]
