Good point Ed, on the piston’s being installed backwards.Also, those 5 1/2 motors are notorious for having broken shock absorber springs in the lower unit, which brings up Mumbles post about how fast the motor can be cranked over. it seems like every time I find one of the old CD motors, the spring is broken… I have an equally tough time finding one with a good powerhead. Just my bad luck I guess.
Ed’s post about installing piston’s reminds me of a V4 that was brought in to the local Marine Mechanics students at our local Vo Tech class. The dealer had been fighting this motor because it would barely even try to run, if at all. It turns out that someone during a rebuild had installed all four cross flow pistons backwards. This was after the students had worked on it for some time, and finally looked inside the cylinder with an inspection camera. This may not be the issue here, but an interesting story anyway!
