mercuryrev Posted August 22 Report Share Posted August 22 Can anyone tell me what the crankcases on an 08 Rev3 were made of please, I seem to recall they are magnesium? I'm rebuilding one and the cases have corroded badly and so I need to refinish them. Thanks in advance Quote Link to comment Share on other sites More sharing options...
lemur Posted August 22 Report Share Posted August 22 Vinegar Magnesium is highly reactive to it, aluminum is not. Quote Link to comment Share on other sites More sharing options...
mcman56 Posted August 23 Report Share Posted August 23 My 2008 had a magnesium side cover that was eaten away by corrosion in the water pump area. I believe the replacement part was aluminium. Quote Link to comment Share on other sites More sharing options...
