Sixes to M8's who's done it? What challenges did you face?

8 is shorter so I imagine there will be some setup to do again

Interesting.....It does seem like people like the M8 more than they used to, would be cool to hear more about them.

These were delivered with 2 inch spacers so same height. We will run them and then decide if an adjustment would be appropriate.

The M8R has a hydro-dynamically more efficient lower gear case than the original M8. The mechanics of this conversion are straight forward however the bullet measures about 1/2" larger in diameter and the skeg is thicker. I was hoping someone had done this and could shed some light on handling characteristics. They are rated at 1600 ft lbs vs 1160 for the #6 so hopefully these will stay on the boat Lol. Seriously, the #6's are great units that can for sure handle more than 1160 Ft lbs. We ran them at at almost 140% of their rated capacity and finished races, broken, worn out yes...but finished all except one.

Aren`t the M8`s double the price?

Probably not double but I don't know what new sixes cost.

Sounds like your going to be spending a lot of $$ and still have breakage issues. Didn't the MTI's break the hell out of these things too?

I don't know. Where did you hear this? I know this drive is improved since it first came out and Merc puts it behind their 1750, and warranties it behind a 1350.
Thanks for the heads up.

In the middle of a #6 to Weisman upgrade for similar reasons.

I'd consider going 6 to 8's a walk in the park..:)
