HIgh RPM in neutral
I have a PSC 34, l998 with Yanmar 3jh2 engine. At full throttle in neutral the Rpms are 4000. This has been checked with a another meter and the reading is accurate. The book says the maximum rpms at the flywheel should be
3600. The mechanics are not sure what is going on. The engine seems to run fine otherwise. What is going on?
