cavitation

[fendersfender]

I own a '85 searay 255 amberjack with twin 3.8L omc stringer drives. problem is that port drive seems to always cavitate while running in swells or turning......port drive NEVER does this. I have checked drive to ensure that the drive is all-the-way down and trimmed properly...it seems to me that twins should always be counter-rotating and mine is not. I have also noticed WOT rpm differences (starboard runs 4600, port runs 4000)??????????? props are identical. I may also mention that boat lists to port when running unless port trim-tab is adjusted. any ideas??

Re: cavitation

i must also add that stringer drives are a pain in the rump and wallet. currently repairing both drives (ball gears, gear set, bearing carrier, bearings, and water pump kits)$$$$$$$$
