The starboard Velvet Drive on our '87 Defever 44 was replaced some years ago with a Twin Disc. That leaves the boat with a 2.5 ratio direct drive transmission on the port side and a 2.44 on the starboard side.
My questions:
1). Is the engine synchronizer equalizing engine or shaft RPMs?
2). If the synchro is matching engine RPMs, am I not getting two different drive speeds at the props due to the different gear ratios in the transmissions and, by definition, the props are not synchronous?
3). During sea trials , we heard a mild "singing" in the starboard aft area. Could this be caused by the differing gear ratios?
4). Should I avoid using the engine synchro, think about replacing the other Velvet Drive or just not worry about it?
Thanks!
