Re: What does this light means

i don't know if this lights has anything to do with the lost of power on my motor. i can start off planing @ 42k-46k RPM then it gradually drops to 28-33k RPM and the boat won't plane again. Does anybody knows what's causing this? :confused:

Low oil level is my thoughts.

Not enough info on PRM issue

i filled the oil tank and the indicator is on the full side. The RPM would hit 42-46k for less than a minute then would gradually drop to 28-33k.

Need to troubleshoot to see if compression is good, if it is loosing spark to one or more cylinders, timing is in spec, or if a fuel issue. \

Also depends on if this motor has ever run properly on this boat
