Proper adjustment for throttle cable/shift cables...

Hello,

Can someone explain how adjust the throttle cable in relation to shifting to forward / reverse?

When I move the stick forward it takes nearly 3/4 of the 90 degree arc before the engine throttle moves increasing the engine speed. Shifting occurs in the first 10-15 degrees, so I would have thought the throttle could be more gradual.

Simply put, it shifts between 12 and 11 o'clock, seems to do nothing from 11-10 o'clock, and throttles the engine between 10 &9 or maybe even 8 o'lock.

1. Does all this sound normal?
2. I hear a little grumbling of the gears as it shifts into forward or reverse, nothing terrible, but you want to wait until it settles before pushing forward. Is this related to adjustment/linkage or something more involved in the lower unit.

I've got a pretty good mercruiser manual but I can't find anything this specific. Any other recommended sources/documentation?

Thank you.

Gene

Post your question and concerns on the Mercruiser I/O forum. But in my opinion, the "grumbling" you hear is normal. That said, you may be taking too much time shifting. Shifting should be done quickly to avoid lower unit clutch dog wear. I also feel the throttle action is normal.
