Are they on to us? I removed the restrictor and took it out for a test run, with the restrictor in the boat maxed out at 5800rpm. With the restrictor removed it zipped right past 6000rpm and hit the rev limiter, at least that’s what I thought. It beeped and wouldn’t rev over 4000 rpm. I thought that was odd for a rev limiter. I shut of the engine and restart and it revs up to 6000 but of course shuts down again.
Fast forward to today when my new prop came in, so I swapped the prop, and my son and I go for what was supposed to be a successful rip, hoping to hit a whopping 25mph! (It’s a Sun Tracker Bass Buggy 16, so it ain’t fast) and the same thing happens, but at 5500 this time, so yeah, not the rev limiter. I have VesselView Mobile so I check that and get a code for air flow too high. Do I need a 60hp ECU too? Is this a new thing? I did a lot of research before this and there isn’t much out there to research, but no mention of error codes. I really don’t want to buy a new ECU, but I might. The other option is to just put the restrictor back in and have a couple less MPH on the rarely visited top end. The new prop is much better at all other RPMs, I just would have liked a free 60hp engine (minus the $150 prop)
I have a video of my shenanigans, it’s somewhere in my boat review. Around the 5:45 mark...
