Chamber of Commerce members asked their views on Brexit
Eligible EU referendum voters on the Isle of Man need to register imminently.
Residents who qualify - those registered to vote in UK elections in the past 15 years - have until 7June to declare their intention to take part in the in-out referendum.
Isle of Man Chamber of Commerce members have been asked for their views on a potential Brexit.
The Chamber's survey indicated around 66% of Island business leaders are in the Remain camp - including 85% of companies trading directly with Europe.
However, 32% insisted they didn't have enough information to decide.
If the UK votes to leave, the Manx Government expects the temporary collapse in guaranteed free trade through Protocol 3 to be 'challenging'.
Reliance would then be on the UK to negotiate a fresh trade union for the Crown Dependencies.
