1. This was not supposed to be a franchise, but when it grossed a ton of money on a shoestring budget they decided to keep it going so that explains why they brought Jason in since his mom had already gotten decapitated.
2. The sequence at the end of the original with Jason grabbing the girl in the boat was a dream if I'm remembering right. So technically since you never saw Jason in the original it makes sense that he's around 33 during Part 2.
3. The original begins in 1958 with the two camp counselors getting killed (who were presumably responsible for Jason's death) and then flashes to "present day" (1980) when the camp is re-opening which pisses Mommy off so she decides to resume her murderous rampage.
4. This franchise was a cash cow and passed through so many directors, producers, actors, writers etc. they basically just freestyled shit as to the way Jason looked, especially after Tom Savini quit after Part 4.
