This New Outboard Extension Kit by Bay Manufacturing is specifically designed to convert select Yamaha F75, F80, F90, and F100 HP outboard motors by adding 5 inches to the midsection.
Manufactured with quality in mind, the kit features spacer housings cast from the same series alloy as the original motors, coupled with durable stainless steel shafts and studs for long-term reliability in the marine environment. This conversion is ideal for optimizing your motor's performance and matching it to a transom requiring a longer shaft length.
PLEASE NOTE: This is an "S" Model kit, which includes the 5″ housing, shift shaft, water tube, and mounting hardware, but does NOT include a driveshaft. If you require a driveshaft, please see our Item #809 kit; otherwise, the driveshaft must be sourced from a Marine Dealer.
