All front mount cylinders built after June 15, 2007 will have this high strength bolt included in the box.High strength tiller bolts can be identified by the marking ‘TFX – ARP’ on the head of the bolt (refer to NOTICE below).
3. HC63xx PRO Cylinders are designed for all those critical high speed, single outboard engine boats, such as Bass, Flats combo Race/Ski and other performance orientated boats capable of speeds in excess of 65 mph. For optimal performance, the use of SeaStar PRO Kevlar Steering Hoses is recommended.
4. HC67xx Tournament cylinders are designed for use with high powered fishing/sport boats. If your application calls for dual or triple outboard engines, is capable of speeds exceeding 55 mp/h and runs ion open water, tournament Cylinders should be used.
