90 EVINRUDE 40 hp long shaft electric start tiller model. Owned it since 1991. Used a few times per year. VRO quit working 4 years ago and it lost lubrication briefly. Scored the rings. It was then bored and repaired with 2 new Wiseco pistons/rings. VRO oil pump is now by-passed as all of them should be (my opinion). The motor has and still does run perfectly and better than when it was new. You can call me for more pictures or questions at 330-204-6872. Lower unit oil changed every year. Motor was never in freezing weather. Always stored in heated garage. Rig was always trailed back home. Never left setting in the water.
