Tachs Out of Synch

[74Alfa]

Hi,

I have a 2000 380 Sundancer and with a Glendenning engine synch setup. One of the cable ends to the center of the front pulley broke and I spent last season synchronizing the engines manually which was not a problem and added it to my project list.

The other day I noticed the starboard tach with ignitions off was reading about 1,300 RPMs while the port rested at 1,000. When bringing the boat on plane the starboard tach pegged and the synch dial was pinned like the starboard engine was at relatively lower power, but we seemed to be in trim.

Any advice?

Thanks.
