More info




  • normal Vire Gear oil should normally be changed every 10 season, and 1000 hours use, or if discoloures.
  • With this improved oil you will seriously increase the life of your gearbox in the hostile marine environment.
  • Discovered from consultation with the technical department at Castrol
  • An uprated oil which could be used in this gearbox, giving TWICE the corrosion protection of Hypoy EP90 etc.
  • no problems mixing it with legacy oil.
  • you can just use this to top up if you cant be bothered to do the change
  • Original Gear oil was designed for normal gearboxes (Hypoy EP/HD 85-140) 
  • Salt air from gear case breather is allowed into gearbox and so corrsosion risk is generally higher on Vire gears and bearings compared to cars. suggest you modify breather insert a foam earplug to bung it, this slows down the air circulation but allows pressure equalisation.

Suggested Procedure for changing/upgrading Vire Gear Oil

  1. place towel in bilges
  2. scissor off half back and sides of a 2 litre ice cream tub which should slip under gearbox drain somehow
  3. remove sump plug (v large nut on lowest end of gearbox) and half fill your tub
  4. replace nut if still flowing, drain tub and repeat 4,5 till it isnt
  5. tighten nut again
  6. remove filler/level plug (Vire 6 it is huge nut on port aft side)(might require tap with hammer and drift if tight?)
  7. using the incorporated pipe, squeeze in enough new imporved oil till the level is on the correct mark(Vire 6 it is just spilling out).
  8. remove tub and towel, dry any spillages.

alternatively use a oil changing pump to suck the oil out through a tube/pump, however it may not clear debris or water so well lying in the bottom ? so always drain from sump bolt too
