    Can't get more than 2400 RPM's

    My baby ran fine for 2.5 days this week. Shut it down to swim and then only had 2400 RPM's. Topped of the gas, I ran it below 1/4 tank which I do not normally do. Same issue. Changed fuel filter. Same. I can get 3300+ RPM's in neutral, but only 2400 in gear. Has anyone expierenced this situation? Any ideas?

      You might want to post the year, make and Horsepower rating of your motor rmarbach.  Someone with a similar setup might have encountered the same thing and fixed it...... hopefully.

      I know that my Mercruiser will go into limp mode under certain conditions in order to protect the engine and drive.

      I have not checked for fishing line around the prop yet, but will next week.

      My unit went into limp mode when the drive oil reservoir was low.  When a Bravo 3 drive is new, I found out it is normal for the reservoir to drop significantly as the voids in the casing of the drive are finally reached and fills in while you run the boat and it is clearly stated to expect it in the Mercruiser Owners Manual.  That is exactly what happened to me.
