Hey all
firstly thanks for letting me join the forum.
I am looking for information on outboard rpm.
I have a 4 stroke Honda BF8D teller outboard. I have just fitted a tachometer
To the motor just to get a ball park on rpm but initially for hours of use
Calculation. But now I have become very interested in the rpm.
There are a few settings on the tachometer unit but at idle in a bucket
I get with setting 1: 680 to 700rpm setting 2: 1260 to 1340 rpm setting
3: 14000 rpm
My owners manual does not show idle rpm but on the internet I found something that showed 900 rpm +/-50
Does anyone have any advice? I know that these units are not the most accurate but now I'm curious. Will idle in a bucket show higher rpm?
