I have a 1987 Cobra outdrive that has a bad lower gearcase. I've looked into buying a rebuilt lower unit but I also saw a place that will do a rebuild of my current gearcase for much less. Here is a link http://www.boatparts.ca/omc-cobra-parts/cobra_sterndrive.html for their full rebuilt units and at the bottom of the page they have pricing for sending your own unit to them. Does anyone have any experience with this company? Is this a good option for getting my drive repaired? Thanks!
