I finally found a supercharger to fit my 4 cylinder 153 cid merc. The Eaton M45 supposedly will bolt right up. Anyone attempted this before and if so how did it go?
I just "completed" a total rebuild of an '83 bomber I/O. Replaced a seized 470 with a 153 cid. I put it on the lake and all went well the first time out. The second time however I noticed a loud knock and vibration when trying to idle. Took it home and tightened the motor mounts on the transom...
I am missing the up wire from my solenoid but can't find a broken wire. I can by pass the switch and it works but I have to straight wire the stud to the hot battery cable. In the pic I need to know where to attach the other end of the newer looking wire at the bottom of pic
I removed a busted MerCruiser 470 and dropped in a MerCruiser 153 cid 4 cylinder. I need a wiring diagram for the new engine, including transom plate wiring. I can not for the life of me get this engine to turn over.
