seadoo motor colors

[JKEP44]

I hear everyone talking about older seadoo motor colors. I don't actually know what years and models this applies to. Mostly I hear of the 580/587 white and Yellow motors. Does anyone actually know if there is an interal difference or if it just breaks up manufacturing dates?

Re: seadoo motor colors

I was told that the first engines were yellow, they were converted snowmobile engines, some changes were made to that engine and it became a white engine and was a jet ski engine. each color denotes a change made to the actual engine.1988 to 1991 were yellow, 1992 up were white
