had a complete rebuild done on my 1989 Bayliner Ciera with an OMC 5.7, they did everything except replace the Valve springs. The original reason for the rebuild was I wasn't getting proper WOT and low top end speed. WOT = 3800 and top speed 27 mph. After rebuild still same problem. Someone suggested to me that weak valve springs would cause the lack of power and low WOT. Can someone confirm this before I pull the motor again and replace the valve springs? Thanks for all the help on this forum. Although I am not a frequent poster I learn a lot just reading the threads.
