Running Crestliner Superhawk 1850. Looking to get new kicker motor. I have 1999 Merc 9.9 4stroke (pull start) on the boat now. Thinking about the Merc 9.9 pro kicker for $3200. Question is get the Pro kicker or keep the old 4 stroke or go with different brand of kicker? Is the Pro kicker worth $3200?
