Variable Oil Ratio

[peter upfield]

I need information on what the actual oil ratio or consumption curve is for a 2001 LX2000. I'm going to build an electronic engine control system and want it to include a metering pump for the oil. I'll need the rpm : oil use curve and I'd rather not have to figure it out myself.

If anyone is interested, the system will start as a fly-by-wire cruise control referenced to synchronized engine rpm or GPS indicated speed. Maybe later I'll add steering and directional control. With the new reverse control enhancements from Thrust Vector, I'm planning on an auto docking sequence by controlling the port and starboard engines and nozzles independently.

Very cool idea.

Are you planning to use existing equipment or to use something like a Pi or Arduino?

I am not aware of Yamaha publishing specs on those oil pumps or of anyone testing the output. If your oil pumps are in good shape it might make sense to work in other areas first.

Yes, but not those specific controllers. I want positive control of the oil ratio. I could monitor the flow but that is difficult and the hardware is more expensive. I will be monitoring cooling water flow.

So awesome - I can't help with the mixture ratio but you could see if @JetBoatPilot could help you with a contact person at Yamaha. They would probably have access to that information or the oil pump manufacturer

I'm not sure either. Maybe call Dragon at Cycle Springs in Clearwater. He's my go-to guy.

 

[peter upfield]

That's where I bought it. Dragon seems like a good guy. I'll see what be says.

 

[JetBoatPilot]

Good deal!

There is a thread on YJB where a guy did some testing on oil pump out put.
