I HAVE A 1999 CHRIS CRAFT CONCEPT 21 BOAT WITH A 350 V8 THAT I PURCHASED WITH DAMAGED LOWER UNIT. iT HAD A 1.60 RATIO UPPER UNIT. I BOUGHT A 1.66 FOR IT. I ALSO BOUGHT A LOWER PART FROM A GUY AND FOUND IT NEEDS TO BE OVERHAULED. NOW IN PROCESS I AM FINDING THAT THERE ARE DIFFERENT RATIOS IN THE LOWER PART AS WELL. THE GEARS IN THE ONE I HAVE ARE 26 TOOTH ON THE LARGE GEAR AND IM NOT SURE OF SMALL ON YET. BUT I SEE TALK OF A 30 TOOTH LARGE AND 17 SMAALL. DOES ANYONE KNOW WHAT I SHOULD BE RUNNING WITH THE ENGINE I HAVE. 30 /17 OR CAN I USE WHAT I HAVE THE 26/? THANKS FOR ANY HELP I MIGHT GET
