Howdy, been on the hunt for a lower end. I have a 2007 Yamaha f250 txr 25 in shaft with dual water pick up standard rotation. Has anyone had any experience with any after market lower units? I been looking for a decent used Yamaha but can't find any. If so what company have you had gd quality lower ends. I see some use Yamaha internals where they can.but are these as gd. Thanks. If anyone has one let me know.
