L136T
The L136T heavy-duty rating adds turbocharged headroom to the proven 8.1-liter platform, giving operators a useful performance step while retaining mechanical governance. That means crisp response and confident mid-range pull for near-shore transits, patrol beats, and tender runs—without introducing the electronic systems some fleets prefer to avoid.
Designed for long, hot days, the L136T’s marine cooling and charge-air path maintain consistent output when ambient temperatures and seawater inlets spike. With the same compact geometry as its naturally aspirated sibling, repowers are straightforward and mounting modifications are minimal.
Serviceability remains a highlight. Filter, belt, and anode access is logical and uncluttered, shortening alongside time and simplifying crew checklists. Commonality of wear parts across the L136 family supports spares management in multi-boat fleets.
Operationally, expect firm thrust off idle, stable speed holding in chop, and efficient cruise at working rpm. IMO Tier I emissions coverage keeps compliance simple for many routes. If your boats need a durable turbocharged inline-six that’s easy to own and run, the L136T heavy-duty package is a smart, cost-effective upgrade.
