It's the porting. The older 2.4L MERCS porting doesn't like low RPM's as I understand it. The porting in the engine wants RPM's to increase the air speed through the engine. Most loopers don't like to be lugged, it's just how loop charged induction works. Now cross flows on the other hand pull great down low. I know even my 2.5L I had was MUCH happier when I jacked the jack plate up and turned it up over 5600 than it was with the prop buried turning 5300. It just felt better.
