DMT25AL

Reverse reduction marine transmission with hydraulically actuated multi-disc clutches .
Suitable for high performance applications in small workboat, fishingboat, etc .
Robust design also withstands continuous duty in workboat applications .
Fully works tested, reliable and simple to install .
Design, manufacture and quality control standards comply with ISO 9001 .
Compatible with all types of engines and propulsion systems, including waterjets and surface-
piercing propellers, as applicable .
Case hardened and precisely ground gear teeth for long life and smooth running .
Output shaft thrust bearing designed to take maximum propeller thrust astern and ahead .
B/W connection integrated with casing .
Smooth and reliable hydraulic shifting with control lever for attachment of push-pull cable .
Suitable for twin engine installations (same torque capacity in ahead or astern mode. Reduction Ratios in ahead or astern are very close.) .
Replaceable oil filter cartridge .
