High Thrust Outboards

[hmattos]

Hi,
We - www.explorermarine.co.uk - have been asked to quote for the build of an 8 metre harbour workboat fitted with twin 60hp outboards - twins are required for security and for good steering control in tight spaces. The MAXIMUM speed allowed is 10 knots, but we do require very good pulling and pushing "tugboat" capabilities.

Do any of you have any experience with the high thrust or Big Foot models in this power, and thus which brand would you suggest.
We are based in the UK, so only new low emissions engines may be specified.
Thanks
HMattos

Yamaha makes high trust outboard engines that are probably the best. They are very powerful, very.

The E tec BRP engines wil have the most torque but whoever has the lowest gear ratio and largest prop diameter will win the tug boat duel
