High RPM

[LBCap'N]

I have an 86 bayliner with aq225E Volvo Penta and a 275 drive. I ran it a few times now but the last time the RPM read high (redlining) without being at WOT, I didn't notice a decrease in speed but I also didn't push it too hard

What does this mean? and how can I fix this?

Re: High RPM

Have you verified the tach is correct?

Re: High RPM

Tach = Tachometer, RPM gauge.

You need a good shop tach to verify. I use the digital tach built into my timing light.
