High RPMS in neutral
I have a 2004 Moomba Outback with the Indmar Assault and when it is idling in neutral the rpms are way too high-up in the 1200-1600 range. It is always worse after the boat has been ran at faster speeds (pulling tubers vs wakesurfing). Has anyone had this issue? Any suggestions as to what could be causing this? TIA

Is it the carb version? Idle air speed may need adjusting or the throttle body could be gummy and sticking open, and might need to be cleaned

You might also look at any vacuum hoses. Bad hoses will cause high idle

It happens about 80% of the time. It's okay for the first little while but the lowest
it will go is around 1000 rpms at rest after it has been running for a little while. Yesterday it was between 1400-1600 after I had been pulling the tube.

I have a similar problem. I own a 2017 Moomba mondo surf edition, just put it in, won’t idle below 1500 rpm, just had the wiring harness replaced this past winter. Dealer told me computer needs to be replaced, any other options before I trailer my boat 2 hours back to the dealer and ruin my Memorial Day weekend?

Oh that sucks. Bad harness on a new boat? What is the reason for the replacement and why would the ECM need to be replaced as well? How did all that come about? Originally Posted by Zoch

Never had a problem with it last summer, when I took it in to winterize it, dealer said they couldn't start it and they replaced the wiring harness. Dealer is telling me over the phone that it is the computer, I tried disconnecting all power and resetting, hasn't worked. Any ideas on how to fix before I trailer it back?
