    Boat not as fast as expected?

    being over-powered means that if there is an issue (accident, etc), you may be 100% at fault. not to mention, your transom is designed for a 150hp. so the forces of the extra 50hp may simply rip it from the boat.

    how to remove prop shaft seal on a duoprop DPS-A ?

    looking at the casting, the bore is a thru-bore and the retention "lip" is the 4 staked areas. that is a cheesy design vs machining a tru lip. however it would save a secondary machining step.
