My walter v drives are rattling at 900 rpms and lower when in gear. It stops when the rpms hit close to 1000+. Any ideas and should I keep using the boat or is this something that is going to get exponentially worse? THx
I have an 88' Carver Voyager and I just read in the manual that there is an acceptable level of rattle in the driveline at low RPM's and if you idle up a bit it should go away. If not then the v-drive and engine may need reallignment. There is also a u-joint that connect the motor to the v-drives and this maybe bad as well if grease was never or seldom used.
While it may not always exist, a rattle is considered normal at lower rpm's. Any inconsistent power can cause this (ie. bad tune). Be sure you have plenty of fresh oil in the drive and proceed. Working on you engine tune would probably reduce or eliminate the rattle.
