For all technical matters, have you checked through Halyard's Top 20 Questions and Answers? If so, and your query isn't covered, then you need to call or email our 'Technical Help line'. Although our friendly staff are always keen to take your call, it's usually more efficient to email our staff with some important information in advance. Such information would include;

Engine; make, type and power rating.
Vessel; sail or power.
Sketch of System; If possible, a hand drawn sketch with as many of the key dimensions placed on it, and sent as a jpeg scan attachment to the email.
