I just rebuilt my 31yo YSM8R
single 8hp
Yanmar with no problem finding parts. I replaced the cylinder sleeve and
seals, the piston with rings, the wrist pin and bushing, the main bearings, both valves and guides and the
exhaust valve seat. I replaced the
oil pump, the injector and the exhuast manifold and
elbow a short time ago too. Depending on where you are the suppliers can be good or the pits. I used Laborde in La. and they got me what I needed without any trouble. I am now confidant that my
motor will last as long as the
boat will..........m
