Re: 3126 or 3126B

Thanks Dave! I mistakingly thought it had to do with the year of manufacture. Glad you were able to set me straight

1ZJ engines are 3126, not 3126B. 3126B is a 3 valve cylinder head, HEUI fuel system, electronic engine.

3126 or 3126B

I just purchased a 2002 Sea Ray with 3126's. How can I tell if they are 3126's or 3126B's? Also, what is the difference between the two?

serial numbers are 1ZJ01883 & 1ZJ01907

Thanks!
