I have just purchased this boat and I need to find a manifold the motor is a I/O GM block 4 cyl. 3.0L 140 OMC cobra outdrive HO . It has a 2brl holly carb that runs across the manifold. I have done some research and found that the manifold is specific to the year. The reinell dealership in salem,OR told me that there is no part number that transfers for a replacement. Also, the heads were changed which in turn changed the manifold. I have called everywhere from TX to Canada with no luck. IF ANYONE HAS ANY IDEAS please please let me know. The casting # I believe is 986984
