1994 mercury outboard won't plane out

[blackmax135]

I started a post a few weeks ago about my lower unit going out because the motor locked up and when I took the foot off it cranked right up.  My mechanic went through the foot and couldn't find anything so I put it back on and took it to the river.

Ran it WOT for about 10 min and all of a sudden it seemed like either I lost power or something in the foot slipped but I did stay on plane when this happened (because I was already on plane) so it didn't seem like a big deal at the time. Had a tournament the next day took it out and it ran fine for about 5 min then it locked up again.  Fished for about 30 min and then it cranked right up, but now my boat does not have the power to get on plane, the highest it will run is 3,000 rpm. So I basically idled around the lake for the tournament the whole weekend.  Has anyone else run into this?  1994 135 Mercury V6 Black Max

Sounds like you need a mechanic. Might be that it's in safe mode, which limits the motor to 3000 rpm.  Check to see if the motor's peeing OK. Does the motor have a built in oil tank? My old Yamaha had a sensor that put it in safe mode if the oil level went too low in the tank, which was about 1/4 full.

It does not have a oil tank and it is peeing fine. It will get over 3000 rpms in neutral.

You need a mechanic then.
