Yamaha 100hp outboard

Hi I'm looking to do a timing belt change on a 1999 yamaha 100hp 4 stroke.
I'm just wondering what is recommended to also change during the timing belt change.
And a point in the right direction to purchase such parts would be much appreciated.
Thanks in advance

Change the tensioner as well.
BHG Marine in Lymington do a cracking mail order service and are really helpful.
Tried to upload a pdf for the manual but it's too large, PM me for a copy.
I did change mine myself but the belt and idler are not cheap!

Hi Swifty. Thanks for the reply.
I will get on to them in the morning., ive only ever heard good things, and they sourced the boat originally.
Visually the belt etc look fine, but i have no record of a change and at around 20 years old, i need that peace of mind lol
