RESTORING THE SPORT ONE PIECE AT A TIME.

I BELIEVE THESE TO BE
1968 YAMAHA SL 350, S 350 & SD 350 JAPAN SNOWMOBILE MODELS.
BUT I AM NOT 100% SURE.
READ BELOW AS TO WHY I THINK THESE ARE
1968 YAMAHA MODELS AND NOT 1969.

THIS JAPANESE YAMAHA SNOWMOBILE BROCHURE AT THE TOP OF THIS PAGE
SHOWS DIFFERENT MODELS THAN
THE 1969 YAMAHA EUROPA SNOWMOBILE BROCHURE OR THE 1969 YAMAHA CANADA / USA BROCHURE.

THE TOP PICTURE ON THIS BROCHURE SHOWS WHAT I THINK IS A 1968 YAMAHA SL 350 SNOWMOBILE.
THE SHAPE OF THE SLED AND OTHER THINGS ON THE 1969 YAMAHA SL 351 SNOWMOBILE ARE DIFFERENT.

ACCORDING TO THIS ARTICLE .........
IN THE FALL OF 1967, YAMAHA PRODUCED 300 - 1968 YAMAHA SL 350 SNOWMOBILES FOR MARKET TESTING.
IN JANUARY 1968, THIS YAMAHA ARTICLE SAYS THAT THEY COMPLETED THE PRODUCTION OF THE 1968 SL350.

THAT WOULD MEAN THAT THEY HAD 2 PRODUCTION RUNS.
SUMMER 1967 OF THE PROTOTYPES AND LATER IN 1967 OR JANUARY 1968 AFTER
THEY WERE SATISFIED WITH THE IMPROVEMENTS ON THEIR NEW MODEL.

CLICK HERE FOR INFORMATION ABOUT THE
SECOND PRODUCTION RUN OF THE 1968 YAMAHA SNOWMOBILES.

THEN THEY STARTED TO PRODUCE THE S 350 AND SD 350 MODELS FOR THE JAPANESE MARKET,
AND THEN
THEY WENT ON TO PRODUCE THE 1969 SL 351 FOR NORTH AMERICA.

FIRST, IT CAN MEAN THAT..............

1. STARTING WITH THE PRODUCTION OF THE 300 - 1968 SL 350 SNOWMOBILES THAT
WERE PRODUCED IN THE SUMMER OR FALL OF 1967, THEY WERE WAITING FOR THE REPORTS ON THEM
BEFORE PROCEEDING. WITH FULL PRODUCTION.

2. AFTER GETTING THE TEST REPORTS BACK FROM FIELD TESTING IN THE FALL OF 1967......

IN LATE 1967 0R JANUARY 1968,  THE FINAL PRODUCTION OF 1968 YAMAHA SL350 SNOWMOBILES WERE MADE.

I THINK, THAT AFTER THEY DID THE TESTING OF THE ORIGINAL 300 SNOWMOBILES FOR 1968 YAMAHA SL 350,
THEY GOT THE REPORTS BACK FROM THE TESTING, THEY DID SOME MODIFICATIONS AND BUILT SOME MORE
1968 YAMAHA SL 350 TO COMPLETE THE 1968 YAMAHA SL 350 PRODUCTION AND THEN DID A 
LATE SEASON ( JANUARY OR FEBRUARY 1968 )
PRODUCTION OF THE 1968 YAMAHA SL 350, S 350 AND SD 350 TO CONTINUE THE TESTING ON ALL MODELS.

AFTER THE PRODUCTION IN JANUARY 1968 OF THE S 350 AND SD 350 MODELS, THEY THEN TURNED THEIR
ATTENTION TO PRODUCING THE 1969 YAMAHA SL 351 MODEL.

IF THIS JAPANESE BROCHURE WAS PROMOTING NEW AND EXCITING MODELS FOR  1969 YAMAHA SNOWMOBILES, 
WHY WOULDN'T THEY SHOW THIS JAPANESE BROCHURE WITH A MAN RIDING A
NEW 1969 SL 351 AND THEN HAVE PICTURES OF THE  NEW 1969 YAMAHA S 350 AND SD 350 MODELS.

IT DOES NOT MAKE SENSE TO SHOW THE NEW EXCITING LINE OF THE 1969 YAMAHA SNOWMOBILES ON THE
JAPANESE BROCHURE WITH A MAN SITTING ON A 1968 YAMAHA SNOWMOBILE.

I BELIEVE THAT THE YAMAHA SNOWMOBILES ON THIS PAGE ARE 
1968 YAMAHA SNOWMOBILES BUT THAT IS JUST MY OPINION.

SO, I THINK THAT THEY DID AN ORIGINAL PRODUCTION OF 300 SNOWMOBILES IN FALL 1967,
SENT THEM FOR FIELD TESTING IN NORTH AMERICA AND JAPAN IN THE FALL OF 1967, AND 
THEN IT SAYS IN JANUARY 1968, THEY COMPLETED PRODUCTION OF THE 1968 SL 350.
SO IF THAT IS THE CASE, THEY MADE MORE THAN A TOTAL OF 300 UNITS TOTAL FOR THE 1968 MODEL LINE.
THEY WOULD HAVE BUILT MORE 1968 YAMAHA SL 350 SNOWMOBILES IN THE 2ND PRODUCTION RUN.

THAT WOULD MEAN THAT THEY PRODUCED THE FOLLOWING 1968 YAMAHA SL 350 SNOWMOBILES ..........

300 BUILT SUMMER / FALL 1967

+

MORE 1968 YAMAHA SL 350 SNOWMOBILES BUILT IN JANUARY 1968.

TOTAL OF 1968 YAMAHA SL 350 SNOWMOBILES = UNKNOWN.

IT IS HARD TO GET THE TRUE HISTORY AFTER SO MANY YEARS HAVE GONE BY.

NOTE !!

ALSO, I HAVE SEARCH THE NEWSPAPERS ON MANY OCCASIONS.  THERE ARE HUNDREDS OF ADS IN THE FALL OF 1967 AND
EARLY 1968 LISTING 1968 YAMAHA SL350 SNOWMOBILES FOR SALE.  SOME DEALERS HAVE UP TO 5 OF THEM TO SELL.
IT DOES NOT MAKE SENSE THAT ALL ACROSS THE USA AND CANADA THAT THERE WERE ONLY 270 - 1968 YAMAHA SLEDS.
