We have a 570 Bass seeker with a 200 efi mercury motor with a 21" Pro speed stainless prop and a 10" jackplate
We have the following problem
At 91Km/h GPS speed we experiance very bad chining to such an extend that we have to trimm the motor right down and slow down to +_ 83km/h it feels like you want to fall out of the boat
We have already dropped the motor as low as possible on the jackplate
We have also spoken to Niel he recons we have to drive throug it?
Can anyone HELP? What do we need to do to fix this?
