what year did correct craft go to standard rotation motors?
RE: what year did correct craft go to standard rotation moto
Not completly sure...but it makes sense that they went standard rotation when they started using the PCM 1.23:1 trans. The trans reverses the rotation at the prop and allowed a standard rotation motor yet maintained right rotation prop. The standard rotation motors were probably less $$ for CC. I think CC made available the new trans in late 1989 boats.
I believe CC still sold boats w/ the 1:1 trans as an option so your boats, if originally equiped that way, would be more unique/rare but not unheard of.

Correct. CC offered the reverse rotation 351w mated to the 1:1 through at least '94 as a base option. Most boats starting in '89 had the 1.23 mated to a standard rotation motor, though.
I'm a little confused here. I have a 1987 S/N 2001 with a PCM 351 and a 1:1 transmission. Comparing the information on the aluminum tag/plate attached to the engine, the firing order on mine matches what the documentation on PCM engines says is standard rotation. For that reason I assume I have a standard rotatiion engine. The original question here was what year did Correct Craft start using standard rotation engines. The previous posts speak of years in the 90's yet I am led to believe my 1987 has standard rotation. Am I all wet here??
I think you better check agian. I would be very surprised if yours is std rotation. An easy way to find out is if you have a 1:1 trans and a RR prop, your engine is RR. I know for sure that CC offered a std rotation w/ the 1.23:1 trans as early as 89 because my Sport has it.
I am just going to throw out some terms, and definitions here.
"standard rotation" This term is for the engine, not the propeller. A standard rotation engine rotates clockwise, standing in front of the engine. The flywheel is away from you.
Propellers are either "right hand" or "left hand"
A right hand propeller will move the boat away from you, if you are behind the boat, when it is rotated clockwise.
A standard rotation engine, hooked up to a direct drive propeller shaft, will require a left hand propeller to move forward.
My personal opinion, but I do not consider Ski Nautique boats with the gear reduction transmission direct drive. There is a pair of gears that change the engine rotation, and the crankshaft of the engine is not in line with the propeller shaft.
By using the reduction transmission, Correct Craft was able to use standard rotation engines, which are less costly to obtain, but I do not know if the total cost of additional transmission expense, minus more economical engines balanced out.
There are some other advantages of the reduction transmission. A higher pitched propeller, turning slower is more efficient. The gear reduction transmission also allows the front end of the propeller shaft to be lower in the boat, reducing the propshaft angle. The angle of the propshaft to the engine crankshaft can also be different, and this allows the engine to sit more level in the boat.

Borg Warner/VD trannies cost the samee no matter the output direction. So yes, CC did save money (~500) by going to a regular rotation motor.
