I have a Mk1 Sonata with the sliding bracket on the transome. My otherwise good o/b performance is marred by periodic vibration seemingly in the bracket. I cannot seem to find an RPM that eliminates this, but some speeds are better than others. Can anybody suggest a solution?
Use the sails and switch the engine off.
THE ONLY ADVICE WE CAN OFFER IS TO PURCHASE AN ELECTRIC ENGINE WHICH WILL BE SILENT AND WILL STOP THE VIBRATION,
BUT PLEASE BE AWARE THAT YOU MAY NEED A VERY LONG EXTENSION LEAD TO PLUG IN THE MAINS AT YOU YACHT CLUB ETC,
We inherited a ‘customised’ engine bracket with our Sonata, which had various rubber dampers added to try to cut down engine noise – during a week of coastal sailing, it started to fall apart, first causing the engine to leap out of the water whenever it was put in reverse (which makes moving about in a marina rather interesting ) and by the time we got home again was in such a state that I have ‘de-customised’ it back to something approaching its original format – ok the engine is quite noisy, but not much more than before – you just have to sail or go into idle if you want to hear the VHF, crew, spouse or anything else!
