How do I adjust neutral position without iNR, a touch screen or available setting mode

[Joatmon]

I have a 2017 twin Rotax Scarab that does not have an iNR adjustment setting, no touch screen and no push button setting to adjust for idle neutral positioning.

To adjust idle neutral positioning I have to adjust the IBR cable at the pump by disconnect the cable end, removing the cotter pin, pulling the nut out of the pocket and turning the nut to adjust the bucket position. There has to be a better way. I have researched the manuals and forums on the subject, but it appears everyone with a Scarab has an electronic method to adjust the neutral position except me.

Will CanDooPro do this?

Help please.

Thanks

Older versions of Scarabs do NOT have electronically controlled neutral positioning. Mine included. No software will fix that. You'd need to retrofit the iBR system, replace the ECU, etc. This is not a small project and I have never seen it done.

With that being said, once it's adjusted, I've never had to touch it again at now 300h. Neutral is damn near perfect for me. Why do you keep having to adjust that? It is a pain to get it right initially.... and ideally it should have been done by the dealer. Cable stretch over time could require some adjustment though. But I haven't experienced that personally.

I have seen older model Scarabs with the electronic adjustment. Guess I’m one of the unlucky ones. I don’t really have to adjust often but would like to be able to adjust when my boat load changes. When I get neutral adjusted with just me in the boat I’m good but a heavy load moves boat forward in neutral. Not sure why load makes a difference other than more draft or pump is lower. Physics.

I don’t use my local dealer and bought the boat1000 miles away.

My adjustment method works. Just not on the fly. I’m a DYI guy.

Thanks for the reply.

Boat load has zero affect on this. The pump, the bucket, everything is moving together. Adjusting the bucket is moving it relative to the jet nozzle. That's it. Once it's adjusted to obtain neutral, there is no further adjustment required unless the cable stretches, something breaks, etc.

So I really don't understand how that's possible unless there's another factor at play. I have never heard of such a thing. Whatever you're experiencing, this isn't it.

Currents, wind, etc.

My tiny 165 doesn't see that either. I've had it fully loaded and empty, still the same neutral. Sea-Doo PWCs (which I own one), also doesn't require any adjustment to neutral based on load. Ever.

I think you're chasing the wrong thing here.

I'm not saying you're not experiencing some sort of issue... Maybe it's another issue.
