Sunreef engine swap

Early in 2023 we were approached to view a Sunreef 40 power. the boat had been delivered and on her first one of the drives had failed. Alongside this the owner was not happy with the performance and wanted to discuss changing propellers and drive gearing to increase he cruising speed.
Although we provided options for the ratio and propeller changes the owner committed to swapping out the engines for more HP and bigger drives to handle it and we were asked to handle the installation.
The original Mercruser 8.2’s have been swapped out for a pair of mercury Racing 700 SCI’s with a Wipple supercharger upgrade. Now producing 860hp a side. The modification did not stop there, the owner specified a silenced underwater exhaust, new external steering system, new electromanual controls and, removal of the external depth sounder to list but a few.
With the installation now complete & lots of custom manufacturing, we are now in the process of testing propellers to fine tune and get the full performance out of the boat and its new equipment.
