    SeaDoo jet boats

    Before I start doing a bunch of research, does anyone know the first year of the DFI 2 stroke used in the SeaDoo jet boats? Which model? Or did they go directly to 4 stroke. Without spending a lot of cash I am looking for a Lake Tahoe legal jet boat. They don't allow EFI two stroke motors on the lake. Thanks for any info you guys might have.

    So you are looking for what model year the first 4-Tec 4-stroke engines appeared in the Sea-Doo jet boats, or the model year when the last of the 2-stroke engines was used?

    I think 2003 was the first year for the 4-Tec engines, but I don't think that all 2003 Sea-Doo models used the newer four-stroke engines.

    Two options were given in 03. 4-tecs were used as an 'option'. 04 was the first year that they no longer offered 2-strokes in any product BRP manufactured.
