I also use the Castrol Grand Prix motorcycle oil in my A-4 direct-drive ( the 10-20w40 flavour ).I think it is SG-CD API spec ( SG has no fuel economy/slippery additives, so it's safe to use on those Paragon transmissions ) SylvainC&C27MkIII

If that oil is one of the newer oils it may have friction modifiers in it which can be too slippery. When first going into reverse the symptom is poor power and excess force on the "gear" shifter. I have an atomic 4 and a straight ( non-V ) Paragon. Reverse operates by clamping a band around the planetary gear hub. The clamping is performed by pulling a wedge shaped bar in a slot. There is no locking mechanism to hold the bar in place but after I switched oils the friction in the cable ( which is brand new ) is enough. Initially I had to pull continuously on reverse to back out of the slip, and it seemed that there was little power for 2 - 8 boat lengths. Then everything was good. I switched to Castrol Grand Prix Motorcycle - Four Stroke that is advertised as being wet clutch compatible. http://answers.canadiantire.ca/answers/9045/product/0281826P/castrol-castrol-grand-prix-motorcycle-four-stroke-questions-answers/questions.htm After the second oil change the difference was significant. I can pull up into reverse, no need to hold it, and there is full power in about 1/2 boat length. Also. lots of prop walk now ;-) Michael Brown Windburn C&C 30-1 _______________________________________________ Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go to the bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
