How close 2 top RPMs on df30a should I be

[Chris k]

After I raise the motor and if I have to start prop switching how close should I try to get to 6300 RPMs and is it okay to go slightly over I would like to get the longest trouble free life possible out of my motor

While doing the same on my motor, I learned that you do NOT want to hit the rev limit. I thought the motor would simply not go any faster, like the computer would just stop applying more "go" when it hit the rev limit. But what it does is much cruder than that. I believe it cuts spark to one of the three cylinders when it hits the rev limit. This does in fact prevent the motor from running any faster, but it runs like poo on 2 cylinders. It will run very rough, then when the revs drop by a hundred or so, it will start running normally again. Then hit the limit again and start missing, etc. Up and down, kind of like someone beating their head against a wall. I propped my boat to max out around 6000 RPM, and I don't miss those extra few RPM. Others may feel differently...

Target 6000rpm and you will be fine.

Thanks for replying do you know if the rev limiter does hit right at 6300 I think stopping around 6 would make more sense I'll shoot for 6 thanks for the info
