I bought a 12 years old Evinrude 40HP VRO.<br /><br />At wintherizing 4 years ago, the dealer vrote on the report: New VRO suggested soon.<br /><br />Why ? The VRO functions. Do I have to buy a new, or can I rebuild with the Maxrules parts kits ?<br /><br />Is 10 years the estimated average safe lifetime of a VRO unit. ( this is type 1 )
