So this is a different motor than the one that was on the boat last week, correct?
Your signature reflects an '87 and this one is an '86.
Has the VRO been gutted? Knowing you, yes.
The parts catalog brings the model up as E225TXCDA if that matters.
Like BS was saying, not sure about the low oil - low rpm safety thing, what year it was implimented but seems to me it was the first year they came out with the VRO system.

Well . . . the shift problem is fixed!! Now onto the the next problem . . . the motor won't go above 2500rpm in gear (with a load). I think it's probably the stator, but I'm no OMC guru. I believe the motor is an 86 or 87 and slow mode didn't happen till 1988/89??? any suggestions. There is decent spark on all 6 clylinders when cranking, and compression is even in all 6. We pulled plug wires on one side and the motor will start . . . and then we did the same on the other side and the motor started, so I don't think it's a power pack. Linkage is advancing through the full range of motion. I'm 100% sure it's electrical, but I'm not sure what else to try beside breaking out a multi-meter and going through each component.

My '84 had the capability to change to dual fuel pumps but from '86 on out I don't see that option.
I'm not sure how to defeat the VRO system and use the fuel pump disconnected from the oil pump.
It sounds like the VRO system is actually working and preventing it from running over 2500 rpms.
You have an almost identical motor to compare to.
That year model had a remote mounted reservior for the oil, is it possible to have a pair of wires that need connecting to simulate a full tank of oil?
