50 hp 2004 mercury rpm's drop
Motor starts up fine, runs a little roughly at low rpms, but at wot the engine runs perfectly for 5-10 seconds at 4900 rpms and then drops to 3000-3200 rpms and wont run any faster. If you drive in low rpms (800-1000) for 5 min, you can get up to 4900 rpms before it drops back down again. Any idea what's up? Everything is close to brand new and even have a water/fuel seperator installed.
