I appreciate you have a problem but ummm....this is a "Mariah" owners club website. I believe "Parker" owners have their own website for your centre console boats at www.classicparker.com. It's not as nice as ours mind you but they should be able to help you out.

Sounds like a timing issue to me. Check your distributor.
