454 mag rev limiter
Can someone tell me where the rev limiter is set at on a stock 2000 454 mag mpi?

Re: 454 mag rev limiter
5150 RPM, I think...

Re: 454 mag rev limiter
I was hoping it was more like 5200..........

Re: 454 mag rev limiter
According to the merc service manual that I have, Rev limiter is set at 5100 with a recommended operating range of 4600-5000. If you want to raise it , go with a MSD soft touch with a 5200 or 5400 chip.You need to find out where your peak HP is and at what rpm it is at. Generally anything over that is not going to produce any better results. You would be just spinning the motor and your HP would start to drop after you have reached your peak rpm. Hope this helps.

Re: 454 mag rev limiter
Ok, 5175?? :evilb:
Seriously, I thought it was like a range of 4600-5000 max so 5100-5200 range might be right for rev limiter.?? |
Re: 454 mag rev limiter
My 1996 502 Mag, GenVI, is set at 5050 according to the Merc Service Manual or 5100 according to the owners manual if that helps at all.

The correct number is 5050

Re: 454 mag rev limiter
How accurate are your tachs? Has anyone noticed when the limiter kicked in what the tach was reading?

Re: 454 mag rev limiter
Good question about tach accuracy. I remenber seeing 5100-5200 on occasion expecting the rev limiter to kick in but it did not.

Re: 454 mag rev limiter
Most boats I have been in including my own are off by as much as 500 rpm + or-
