Prop 1999 30 Mainship pilot sedan
Looking at changing prop, due to vibration issues , after 2200 rpms
All major systems were check, and passed .... Alignment , shaft, cutless bearing, and old prop, 22X26X4 LH,
Running Cummins 6bta, WOT 2600,
I understand there were vibration issues on the older boats, and Mainship added a 5 blade prop to help the issue.....
