M8 drive issues behind 1350 Q4
Merc M8 drives not standing up to the HP of the 1350 Q4, heard merc is having issues with M8s, and are going back to the #6 for reliability. Is this true, anybody else with issues with M8s.

The 6 is not rated for 1350hp so it wouldn't be Mercury doing this and the 1350 is sold as a motor/drive package. Im not positive whats avail today but the M8 has / had(?) limited gearing options. Some guys went back to the 6's for gear ratio selection.

As to the #6 horsepower ratings-i am living proof that they do live at 1800 plus.Several M8 owners have switched back to the #6 and gained substancial top end numbers thru lower slip.

The gear ratios they offer are intended to keep the speeds down.They do have a new ratio for the M8 taller than the current 1.30 and 1.43.

...and how long can the #6's live at 1800+ hp survive on your Skater before service or major failures?
