Two different versions of the same airplane. There were several earlier versions of the aircraft, each with slight improvements or changes from the original. The 'J' model introduced a key operated electric starter, along with rocker type electrical switches to replace the older style "toggle" switches
The Cessna 150 uses an air cooled engine.
150 mph
The original M model Cessna had 150 hp

The empty weight of a Cessna 150 is 1,111 lb (504 kg) the maximum takeoff weight is 1,600 lb (730 kg).
Which one? A Cessna 150 has two seats. A Citation Sovereign has 12.
Cessna C-150 can hold 1 passenger. Cessna C-172 can hold 3 passengers
Two
The Cessna 150 is a small two seat tail wheel aircraft. It is very popular as a trainer and a glider tug for groups like Air Cadets.
Weights vary with airplanes (even those coming out of the same assembly line!) but the average is a little less than 1000 pounds (986 poounds).
The 150 and 152 both have 2 blade propellers.
NO! Aircraft maintenance and repair are quite heavily regulated, and only the parts specified by the aircraft manufacturer are allowed. Swapping parts between airplanes requires testing and government approval. Since the 150 and 152 use different engines, swapping parts between them would not be allowed.
