Bouchard Special Engine
BSE
A brief history by year.

 

1971
Research and Development

 
- A 440 BSE F/A first appeared in a Bullet chassis
- The sleds' model number suggests it is a KMS engine
(1XR7K) but the BSE's were different
- KMS (Kebec Moto-Ski) engines debuted in 1970 as limited hand built versions
- Wider use in 1971 Bullets in 295, 340, 650, and 800 versions but quality issues during mass manufacture and the termination of the Bullet program caused the discontinuation of KMS for 1972.

 
1972
Incorporation into the Lineup
 
- BSE engines first appeared in the model lineup in 250, 340, and 440 axial fan versions
- Available in the Cadet 250M, Zephyr 340T + 440T, MS-18 440T, and Grand Prix 340T-SS + 440T-SS
- The resemblence to a CCW is not coincidence.  BSE's were manufactured in Japan by the same people who brought us CCW and        Kiortz but to slightly different specs.
 
1973
Exclusive use of BSE's
 
- All 1973 Moto-Skis came through with BSE's.
- 250, 340, and 440 fan engines stayed the same but were joined by a 295 twin fan, 400 twin F/A, 440 twin F/A, and a 340 triple F/A
- The 295 was a rotax in desguise.  It is the same basic motor as found in the '73 ski-doo's and even has a "Made in Austria" tag
- The 400, 440, and 340 triple F/A engines were also rotax engines slightly reworked
- Models using BSE's were: Cadet 250 (fan) , Capri 295, 340, and 440 (fans), Zephyr 340 and 440 (fans), "F" 295, 340, and 440 (fans), "S" 400(F/A) and 440 (F/A), "SR" 340 F/A triple.
 
1974
Writing on the Wall
 

- Last year of the Japanese built BSE.
-340T and 440T were reworked and became a 6 port design with the 440 going from 33 to 40 H.P.

- 250, 295, 400 did not change.

- Cadet 250, Capri 295, Futura 295, 340, and 440, Chimo 440, Grand Sport T.S. 400, Grand Sport 440
 

1975-
Hello Rotax
 
- Last year of the BSE name.
- Only the Chimo 440, Grand Sport 440, and Cadet 250 use BSE engines.  All other models use Rotax motors actually displaying the Rotax name.
- By 1976 all models use Rotax engines and Moto-Skis are completely Bombardier designs
