After being laid up for a couple of weeks while we were away, I noticed today, a small puddle of oil under the gearbox. It is gearbox oil and I would say that the puddle amounted to about 100ml (but who knows really). I have checked underneath and can see no obvious leaks from speedo drive, reversing light switch or seal from gearbox to prop shaft. The only noticeable spot of oil was on the centre bolt that goes through the gearbox mount and after talking to Richard Price, this bolt goes into a blank threaded hole. Any ideas where this oil could be coming from? The rest of the gearbox assembly looks quite dry. My plan now is to check the oil level and watch for any further leaks and then decide what to do from there really. My question is "what oil do I put in the gearbox?" ( Type 9 five speed )
