I´m very sorry to hear that.
What happened to you, happened to me..... and to some many other buyers, we were thinking HANSE knows what they were doing. They were not!
Their replies were astonishing, like:
a) That happens only in Spain
b) You are the only one reporting those problems
c) We never heard about vibrations before
I can offer you free assistance, You may not need to put a V strut like the one on the pics posted here before.
I have designed the fix of a HANSE 630 with similar problems.
I´m enclosing here two pics with the solution.
The repair was made in Barcelona
again, is cheaper that the V strut. but shaft, cv joint, bearings, need all to be changed and the engine
has to be hoisted on his room and realigned on its vibration mounts.
But anyway you will need to change your propeller
as the Gori is not appropiate for you yacht.
After this repair you can barely hear the engine
at 2000 rpm
outside and you will get no vibration at 3300 rpm
. The yacht will peak 9 knots at 3300- 3500 rpm with a suitable folding prop without any ¨överdrive¨.
I´m still wearing the AUTOPROP: I can't recommend this propeller
as it is not practical , you need to clean the prop every month as it is very sensible to organic growth.
I can recommend other propellers that theorically can perform as good as the AUTOPROP without the problems associated.
You can leave the yatch as is now, but if you are along range cruiser community , this will break your nerves up.
will not be damaged, The epoxy
Hanse hull is the best think in this Yacht but the SS shaft, Cv joint, and last but nor least the cutlass bearings will all be damaged sooner or later.
The most sensitive part is the last (deadwood mount) cutlass bearing, this vibration will eat this bearing in two months, worsening the shaft vibration like a feedback.

Thankyou for the very appasionate informations.
