Any clutch can be used as long as the adjustments (arms and springs) are cut for the power curve of a 644cc Mercury engine.

Hurricanes used Salsbury 910 clutches on the 72 model which was made in 1971 and very early (January) 1972. Salsbury 850 clutches were used on Hurricanes made after 2/72.

Unfortunately after 35 years it may not have the original clutch on it. A picture to identify the clutch is best.

What is the compression in PSI both sides?

Electric Start was a dealer installed option (in kit form). Parts book indicates that the regulator has a serial number split.

I have both. $25 each plus shipping.

I will need your serial number to tell if I have it.

Please send it to me in a PM.
