NEW MODEL 805A For Offshore Series 225, 250 & 300hp

Long Shaft Extension Kits

Bay has expanded its line of kits to convert many Mariner and Yamaha outboards to long or extra long shaft. Even though they cost a fraction of factory parts alone to convert standard motors to long shaft, Bay extension kits are designed and manufactured of top quality materials to give lasting reliability to your outboard motor.

Using compatible alloys in both the housings, shafts, and studs, these kits are as corrosion resistant as the motor itself. All shaft and studs are of stainless steel and housings are cast of the same type of alloy as used in the motors.

Dealer pricing is available pending proper qualifications.
