Following reliability problems with their inboard diesel engine, Calypso Marine decided to re-engine a 9 metre cabin Ribcraft with twin Suzuki 200 hp outboards and to purchase a new 7.8 metre Ribcraft with twin Suzuki 150 hp outboards.

Used as safety boats to support work on the Forth Rail Bridge, “the new fast craft perform a vital service transferring crew and stores from ships on the Forth”. The decision to replace inboard diesel with outboard engines was due to a number of factors, according to Calypso's joint owner, Stuart Taylor, who said:

"We had difficulty working with the existing diesel engine – we are commercial operators and can't afford to have the boat out of service. With the new outboards we could change an engine in a few hours in the event of a major failure, compared to three or four days of downtime for the inboard engine. The new Suzuki engines are much quieter and less smoky than the diesel inboard. A major advantage is the added working deck space inside the boat without the big inboard engine box."

Ribcraft Sales Manager, Jason Purvey, said: "Durability and reliability are the top priorities for this sector of the market and Suzuki are our first choice of outboard motor for our commercial customers. The competitive price, back-up from Suzuki and two-year commercial warranty form a package that really speaks for itself.”
