Solid Engine Mounts
I have recently purchased a heavy displacement Laurent Giles Vertue fitted with a Bukh DV 18ME twin cylinder (1990 vintage). The engine has very low hours and appears to be in excellent condition, however it has been fitted on solid timber engine mounts through bolted directly to the longitudinal hull bearers. The engine is quite noisy; I believe the engine mounts to be the cause as the entire hull seems to act like an amplifier. On the delivery trip we were forced to motor for nine hours, due to lack of wind. The engine performed faultlessly, except for the noise levels, although at the end of that trip I noticed a few hoses had worked loose. Once tightened, no further problems have been experienced.
The solid mounts were professionally fitted a few months ago, probably to save cost. I could probably get used to the noise levels but I am concerned that this set up is not ideal and could potentially cause problems down the track. Bukh recommend flexible mounts, but these cost around A$750 plus the cost and hassle of fitting. Could anyone advise if solid mounts are acceptable on this type of engine?
