we are a very active dive club in dublin with 40 members. we are to receive shortly our new tornado 8,5 metre.
the BIG debate at the moment is Single or Twin engine? two or four stroke?
what would you recommend.
in advance
thank you

I would recommend a 2 stroke for dependability and more power to weight ratio. They use more gas and you need to mix oil with the gas (50:1) for them to work. How many engines depends on size of boat and load.
