45 hp chrysler leg repair

[jamuss]

I have a 45 hp chrysler motor, model 454BG, ser #1902. I need to replace the lower housing but can't seem to get the output shaft out. I was hoping someone could tell me how to do this.

Are you talking propeller shaft or drive shaft? What is the model number of the motor. Late 60 to mid 1984 there were some changes.

hello chysler fans,
the lower leg on my '72 45 hp chrysler just separated(the lower seam). When the motor shifted from nuetral to forward, it clunked hard and created an 1/8" gap in the seam. I can see a threaded stud inside. I have never worked on these engines and have not heard good things.

question- how much should/does a complete lower unit overhall cost in parts? is it worth trying to keep it alive? Do I have a larger problem with the clutch?

any advice from the oldtimers would be great.
