Barrus test the new Mercury FourStroke engines

Please Share!

Ben Allen, General Manager of EP Barrus Marine Leisure Division and his Technical Service Manager, Lee Allen have been in Miami testing the new FourStroke engines from Fond du Lac.

They kindly sent Powerboat Racing World their first impressions of the new Mercury outboards.

Boat Test Carried out:

  • Boston Whaler 250 Outrage
  • Twin Mercury 225HP 3.4 Liter V-6 FourStroke
  • Boat Weight – 4000kg (6 persons on board)
  • Top Speed 51mph
  • 6000 RPM – WOT
  • WOT – 150LPH

For a heavy boat the engines performed incredibly well.

The torque has been massively increased improving hole shot.

A standing start to 50 mph was noticeably different from the Verado L4 reaching WOT and max speed in a much quicker time.

The power can be felt right the way through the rev band pushing you back into your seat all the way up to WOT.

This new platform features adaptive speed control maintaining RPM regardless of conditions i.e. no drop of RPM in turns or sharp manoeuvres.


Boat Test Carried out:

  • Blackfin 242 CC
  • Twin 200 HP 3.4 Liter V-6 FourStroke
  • Boat Weight 2700g (3 persons on board)
  • Top Speed 53 mph
  • 5800RPM – WOT

Again this was an impressive setup with comfortable cruising around 30 mph at 3500 rpm using a total of 46LPH.

The power could be felt right the way through the rev bands.

When throttling up from 3500 rpm to WOT the power was intense and you good feel the torque of the engine picking the boat up and moving it along the water effortlessly.


The new 150 Pro XS was on display in Miami.

It follows the styling of the 115 Pro XS which made its debut in 2016.

Talking to the guys at Mercury, the testing that was carried out on this boat in conjunction with some of the top Bass fishing boat teams and they are reporting strong results – Beating its competitors in both hole shot and top end speed.

We believe that Barrus will have the same success with this engine that we have experienced with the Mercury 115 Pro XS, of which demand is growing everyday within both the leisure and racing sectors.

Barrus is the UK distributor for Mercury Marine.
