Yamaha F60 Compression numbers? and Manual

Does anyone know the figures I should be getting for compression on my Yamaha F60 4stroke? It's getting on a bit now and seems to be down on power, I thought it would be best to start on the possible major problems before moving on to something fiddly.

Is there a downloadable manual for this engine too? It would make things a lot easier.

thanks in advance
