Hi: I am repowering my Ranger 680T with a 50 ETEC. The ETEC has a tiller handle that is considerable longer than my current outboard. The seat is fixed, so I am considering adding a 6" jackplate to setback the outboard and bring the tiller handle into a more comfortable position. Will the jackplate complicate the performance of my engine?

What is the difference between manual jackplates, or are they all basically the same?

THANK YOU!!!!!
