I'll share my experience. I bought a used boat with twin Mercury outboard 2 cycle motors (late 80's) that had oil injection. All was well for about a year, then while cruising one of the motors began to miss, then shutdown--took maybe ten to fifteen seconds. The problem was the oil pump is run off the crank shaft of the motor and the gear had shredded, consequently destroying the motor. By the time the temp alarm went off the motor was destroyed. Learned later that Mercury used a FIBER gear so that when it destroyed itself, it wouldn't throw metal parts throughout the motor--lots of good that did. Power heads are expensive.

My advice, and that of lots of experienced mechanics. When your warranty runs out, start pre-mixing.
