I get a vibration when in forward gear
, that's noticable between 1300 rpm
and 2000. So I end up cruising at either 1300 or 2000rpm. It results in cupboard doors etc. vibrating throughout the boat.
is that a local boatyard installed a new Hurth transmission
, had the prop balanced, and a new propshaft was installed, all just before I bought the boat 2 years ago. It's had the vibration since I bought it.
This is a Universal 5424 with 2:1 Hurth transmission
and 3 bladed prop.
I'm assuming the two most likely causes are the prop, and a misaligned driveshaft? How can the driveshaft alignment be improved and can this be done in the slip?
I'm also wondering if the problem could be worn out engine mounts
. They are 28 years old now.
One problem is I don't really know what to expect. Anyone else with a 3 cylinder?
