Rough running...
Posted: Mon Apr 15, 2013 4:20 am
Hello All.
We did it!... We went out yesterday morning on our maiden voyage. Thank God we were with the mechanic from the place we bought our boat. It was rough running, well actually, it ran awesome but after a minute or two at perfect constant RPM, lets say 5800, it quickly dropped to 5K then a few seconds later 4200, then 3500... Eventually, if I didn't adjust the throttle position, it would almost get to idle. I would bring it back to idle for a few moments and could start the whole process over again. 6K doing about 22-23 MPH, after a few moments, 5200, 3500... It is a 20' Princecraft Vantage 20L with a Merc 75 HP 4 stroke hanging off the back. The mech kept it there and said they were going to look at it today. What do you think? Thank you for your help...
Sincerely,
Rich
