Julie - HELP
 

I just replaced a pair of 330 hp mercs with 502 mpi's (415 hp), was running 22 p hydromotives which worked best, now I get porpusing or horrible chine walk....

I need a reasonable amount of stern lift, brovos give me a LOT of porposing....

and suggestions?

Oh boy new power! Well it sounds like we need to do some dial in work. I will pull your prior data and then consider all of the upgrades. We know you have some behavioral issues from the get go so we will have to make some necessary changes to the lifting characturistics, of the boat. Not to worry we'll get it! Call me at the office and we get started.
