Servicing my 06 50 yam 2 stroke

Hi fellas just looking for some advice on whether i should attempt to do my own service on my 2006 yamaha 50 2 stroke or would it be advised to have someone do it , ive been looking for a service manual download and cant find one if anyone has any info on where and how to download one that would be gold and how do i find the engine hours ? Went to rotto today trollin for macks as we have had a good strike rate along the south side ,nothing like last week no bait balls no active birds no tuna and no macks , there was a couple of boats out trollin would like to no if they came across any . After around 4 hours of trollin had a bottom bash which resulted in a good size skippy a size blk ass small sambo and 3 under size dhus it was the maiden voyage for my mates boat and lucky the first fish to hit the deck wasnt a wrasse but the skippy anyway hope to get back out there when the wind dies and hopefully more macks
