I have a 96 javelin 400tdc with a johnson 225hp. It has a 10" backplate and a 25p tempest prop. At wot and trimmed up im at 62mph but my issue is that it sounds and feels like the props loosing grip In The water. I can Hear it catch and then slip in the water and it feels like the boat goes side to side a bit when it happens. I've tried all different prop to pad heights and trimminig the motor more and less. Does anyone have any ideas of what's causing this or what it is doin? Thank you.
