Euro I heavy duty emission standards were introduced in 1992, followed by the introduction of Euro II regulations in 1996. The actual standards are not particularly relevant, however the performance upgrades to the B Series engine enabling it meet those low emission standards provide us with first class starting point for a marine engine.
The Perkins T6.354 was a great motor in its time, however, spares are becoming rarer and more expensive to source. Just taking UK red diesel fuel prices into consideration, the more efficient Cummins engine will save money every time you run it and is easier to keep oil tight.
Based on the work we have done so far using a Euro I or II automotive base motor we have developed three distinct power ratings which cover Fairey boats as well as other applications:
180 hp at 2,600 rpm.
A good replacement for the T6.354 at 145HP as the existing gearbox ratio, propeller shaft, seal and p-bracket, and even propellor pitch may be maintained.
220 hp at 2,600 optional 2,800 rpm
A good engine for a Huntsman 28 or Huntress, giving a distinct turn of speed and the equivalent power output to a Ford Mermaid or Sabre. This would also work well in a later Huntsman 31 with the racing hull or a suitably reinforced earlier vessel.
260 hp at 2,600 optional 2,800 rpm
For the out and out Speed Merchant - but make sure your wooden Fairey Hull is strong enough to take the stresses that these speeds will generate. This engine option is inter-cooled.
The 2800 speed ratings are targeted at early Huntsman 28's with small propeller aperture and could also be used where a reduction gearbox is required..
