"Blokewithaboat" Sorry I think you should be changing your gearbox oil daily until you know what condition the gearbox is in and more importantly until you know the oil you are using will fully emulsify with water. A lot of the oils available now will not emulsify even if they say they do, I learnt this the hard way.blokewithaboat wrote:Seems a bit excessive renewing the contents of your gearbox every time. Perhaps Charles should have said CHECK your oil level after each use.
It is important to check.
I know gear oil is important, but even so, if after around 10 hours of usage you find your gearbox has leaked THAT much oil there must be something seriously wrong with it.
Whenever i have a motor in storage for a long time i'll often put something underneath the gearbox and prop to act like a drip tray and keep an eye out for any oil that might leak out. Anything that leaks out over time is then contained within this drip tray and this way i can judge how bad an oil leak might be. Crude but pretty effective.
