I have a 1996 Volvo Penta 3.0GSP that powers a SX Cobra drive. Shorty after the first ride with the boat, i noticed when I turn the wheel all the way to the left, it gets stuck and is very difficult to then steer back to the right. Also when the drive sticks, the engine slows down, very noticeably. Mechanic says this is normal for this drive, but it certainly seems odd. Anyone know if this is in fact normal for the SX Cobra?
