Saving Old Seagulls

Thanks all who replied
the seagull is used as a backup outboard and is stored on its side so thats why i wondered. but i feel reassured now thanks to your posts and the welcome to the world of seagulls. the oil leaks out of the exhaust so i will have to top it up when i use it .
thanks again for ...

I have a 102 plus. which seems to be okay on running. when I layed the engine down in the bottom of my boat as it is the backup engine. the gearox oil leaks out from just above the gearbox. is this normal? is there a seal gone? how do I fixit? thanks
