  • Cobalt 262- what's shakin?

    Hey guys, strange issue here! We have the '02 8.2L 425hp HO volvo penta GXi. Occasionally when engine is started the ENTIRE boat shakes. Engine is not missing but whole boat wiggles. If i immediately shut it down, wait a few secs and restart it may or may not occur again. Only happens when starting, never appears if engine is already running or in gear. Is there a tiller stabilizer that could b worn? Boat has about 440 hrs, always been maintained by dealer removing outdrive each winter for service.
    Any ideas would b appreciated,

      We have an '02 262 with 375HP VP that had the exact same symptoms you describe. Turned out the steering actuator was leaking which causes the power steering to rock back-forth - the shaking. Replacing the actuator solved the problem, but it's not an inexpensive part.
