[QUOTE="Pappy, post: 403630, member: 3278"] Depending on the tachometer you may have the wrong setting on the tach and it is reading at half the true RPM. If you have a wasted spark system on the ignition the setting should be at 360 and if it is individual cylinder ignition it would be on 720 depending on the tachometer. The other indicator is that the boat would be going at barely above planning speed or not planning at all and I notice you did not say anything about that....just the opposite. [/QUOTE]
