Since the IOM is self governing and low tax, it would not be impossible for them to run a lottery (the TT Treasure) after the prizes and admin costs they could build a permanent TT museum, a community centre for wayward youth and have some left over to hand out a few bonus prizes for the overworked marshals (except Gorse Lea who are already well rewarded with cakes and sticky buns). Stuff like petrol vouchers, Steam Packet tickets or as Colin rightly says something for the long suffering partners which has nothing to do with motorcycle road racing.

Tickets £5 pounds each £200,000 tickets = £1 million
-£100,000 for lottery administration = £900,000
-£50,000 for maintenance on heritage buildings (the govt. already own some) = £850,000
-£200,000 staffing and set up costs 1 year = £650,000
-£50,000 gifts for marshals = £600,000
-£300,000 for trust fund for permanent income for museum and youth centre = £300,000
-£200,000 for lottery prize winners = £100,000 left over for consolidated revenue (black tie dinners you know the sort of thing they like).

If it were launched on the internet as well as at both the Manx and the TT then ticket sales of 200,000 is not impossible. If one were run every year for 10 years the trust fund would = £ 3 million earning at least £200,000 PA so the museum and youth centre would be self funding. You could always save money by paying Bill Snelling and John Foster peppercorn salaries to run them.

Increased tourism and reduced crime they couldn't go wrong.
