I have a 1984 Charger inboard/outboard with an OMC 305 engine. We have been having power issues and would like to know if anyone has encountered the same thing or may have suggestions on what the issue may be. Here is the issue: the boat starts and runs great. When we are in the water and engage the throttle to full power the RPM's go up but it takes a long time for the boat to actually catch up to the RPM. It seems like its about a 5 minute delay before it picks up speed. When it does it takes off and runs great. After its been throttled down for awhile it does it all over again. We recently had a new impeller installed recently but it was doing this before it was installed. Anyone have any suggestions?
