to pump or not

[THEFERMANATOR]

Many people don't have any faith in the oil injection system. Many times the alarm will sound, but normally you can't shut em down in time and the damage is already done. The JOHNNY-RUDE VRO(trademark for OMC's oil injection) system really gave a black eyye to oil injection system's. The first ones didn't have an alrm, and the pump's were a completely new design and gave some trouble. Plus many boater's had never had a 2-stroke, let alone one with oil injection. Needless to say many didn't fill the reservoir, but the VRO got blamed. Or they would buy the cheapest oil they could get that wasn't even meant for oil injection(there are different viscosity's to 2-stroke oil), and the VRO got blamed as well for operator error. But the simplest solution is to just pre-mix the fuel and then you know the oil is there.

I personally wouldn't run a JOHNNY-RUDE(excluding the DFI's) with oil injection. And I bypassed it on my MERCURY because of the failure prone plastic(yes I said plastic) crank gear that drives a metal oil pump driveshaft. But I ran them on all of my SUZUKI's(with SUZUKI oil, there oil is THICK! compared to regular TCW 3), and never thought of bypassing a YAMAHA's either. Oil injection system's can be very reliable, but they do require operator maintence every once in a while.
