MERC 3.0 CLACKING AT W.O.T
Hi,
I have a mercruiser 3.0 with an Alpha 1 outdrive. the engine runs great up to about 3/4 throttle, but when I go to w.o.t. the engine still runs fine but it starts to make a loud clacking sound. I sat beside the engine with the cover off while someone else was driving to try to determine if it was caused by something vibrating, but it appears to be coming from inside the engine. Any ideas what this might be? Thanks, |
