JCB Mermaid Engines

Compact Power, Plain and Simple

JCB Mermaid marine engines are compact diesels for owners who want honest power without a giant engine room. Small cruisers, fishing boats and light workboats suit them well.

One Family, Eight Power Levels

Every listing belongs to the same J-444 family, running from 74 hp up to 160 hp. That makes the choice easier, because you are comparing steps on a single ladder, not strangers.

Choosing in Four Steps

• Weigh the boat with passengers and gear: heavier hulls need the upper steps
• Think about speed: a relaxed cruise needs far less than a quick dash
• Count your days afloat: daily work puts more hours on the engine
• Leave some spare power, because an engine that never strains feels calmer to live with

The Keel-Cooled Option

One listing, the J-444NA HE at 85 hp, is keel cooled. Instead of pulling water through the engine, it passes heat to the water outside the hull.

Where Each Level Fits

• 74 to 85 hp: gentle, economical running for the smallest hulls
• 100 to 114 hp: a comfortable margin for family trips and everyday jobs
• 125 to 130 hp: heavier loads and steadier progress against wind and tide
• 145 to 160 hp: the strongest steps in the family, for the biggest craft it suits

Finding Your Step

Tell Engine-Car sp. z o.o. how heavy your boat is and how you use it, and the right step on the ladder will be easy to spot.
