The 27-year old also put in a lap of 128.445mph to become the third fastest rider ever to have lapped the Mountain Circuit.
Donald raced at the event last year in the 600 class, and this year had to cope with broken heels as the result of a crash during the Northwest 200 a couple of weeks before.
Donald said: "These have got to be the two toughest weeks of racing I've ever known what_with setting up three machines and trying to learn the track more so to end up with 2nd in the Senior is unreal. When I came here, I was hoping to get 4-top ten finishes and lap at 125mph so to achieve what I have done has exceeded all of my expectations. I knew I had to blitz the first lap in the Senior to stand any chance and it worked out perfectly, putting me in with a great chance. Once I'd done this, I set about chasing down Ian Lougher and I ended up passing him three times due to the slow getaway from the pits each time! He's not easy to pass as he uses all the course but we did it in the end and I'm stoked with how the whole week has gone. The result makes all the hard work worthwhile and I couldn't have done it without the boys in the team - they all worked so hard and it's great to reward them with 2nd." (Image: www.iomtt.com).
