Hey Folks,

I have a Mud Buddy Mini 23 that has high performance cams and muffler. Last season I threw a rod and had to replace the short block. I got it back and the motor runs fine until under a load or long periods of running full throttle where it seems to run hot and looses power. The motor runs like it is under incredible stress and seems to power down. The mechanic that worked on it put a new rev limiter on it, and it is a 5000-5200 limiter. I called Mud buddy yesterday with my issue not knowing exactly what I had and they recommended a 4600-4800 limiter. I have emailed them already this morning, but thought I'd throw it out here to see what you guys thought. Am I running the right limiter or is this my problem? Any thoughts on carb upgrades or propellers that might help my performance? My main concern is not blowing up another block. Motor is on a 16 ft. x 48" flat alumacraft. Thanks in advance for your comments.

45/4600 limiter on stock rods imo.Double check valve adjustments. Make sure carb isn't jetted lean

You say you have a cam and exhaust and mention a carb upgrade. Are you running an aftermarket carb?
