rayglass 730 repower

In Oct 2022, Marine Power Systems Ltd performed a repower of a Rayglass 730, replacing the ageing Yamaha inboard with a brand new Steyr 280hp engine and Bravo III drive.

The transom design of the Rayglass 730 can make it difficult to find an engine that will fit and owners are often limited in their choices. The Steyr SE286E40 however is smaller than the Yamaha, around 100kg lighter and poduces an additional 80hp of power and is therefore a logical choice for any owner wishing to upgrade their boat. 

The Steyr SE286E40 is also a modern EPA tier III engine which is an important factor since new emission regulations came in to force on 1 Jan 2023. 

The work was completed over the course of 5 weeks and included a complete replacement of fuel, seawater, engine electronics and  control components. The opportunity was also taken to upgrade to hydraulic steering which allows for the addition of an autopilot; a popular system on any modern boat.

The Yamaha stern drive was removed and replaced with a brand new Bravo III drive system. The Bravo III works extremely well with the Steyr inboard and provided excellent hole shot, top speed and fuel efficiency throughout the range. 

The sea trial revealed a significant improvement in vessel performance over the original Yamaha. Top speed was recorded at 35 knots and fuel burn of 28 L/hr at 25 knots cruise.
