Malibu Response Txi

The Response TXi's reputation precedes it. There is a reason more professional skiers choose to ride behind the TXi - it's all about winning and the TXi is a proven competition winner.

MALIBU MONSOON ENGINES

Malibu's Monsoon M5Di and M6Di engines were specifically designed to give Malibu owners even more reliability, durability and lower emissions.

MALIBU MONSOON ENGINES

DESIGNED, BUILT AND BACKED BY MALIBU

The new Malibu Monsoon line of engines, the M5Di, M6Di, and the LT4, were developed by Malibu to offer unmatched performance, fuel economy, reliability and sound reduction.

Malibu was able to accomplish this feat by bringing engine production in-house. The engine experts at Malibu worked with industry leaders like GM® Marine, Roush®, Davinci®, and McLaren Engineering® to design and perform the research and development necessary to introduce a line of in-board engines to the towboat industry like no other.

MALIBU Monsoon M5Di

TORQUE - 400 FT-LBS @ 3800 rpm
POWER - 370 HP @ 5600 rpm

Whether you’re going for another buoy or generating surf swells, Malibu’s new M5Di has the power to get you there with more efficiency than ever before.

MALIBU Monsoon M6Di

TORQUE - 460 FT-LBS @ 3800 rpm
POWER - 430 HP @ 5600 rpm
Designed to be the standard engine in some of largest Malibu boats and the first step up in the powertrain options, the M6Di still has the lowest sound level at various RPMs and fuel economy levels comparable to smaller engines.

LET’S Talk Torque

It’s not how fast you can pull a rider or skier (that’s horse power), it’s about getting the rider out of the hole quickly and consistently with a boat full of ballast and friends – and that’s all about torque curve. This has been the driving factor behind the Malibu Monsoon direct injection engines. M5Di, M6Di & LT4 are tailor made by Malibu for water sports – meaning maximum power is delivered early in the torque curve to give you a boat that never bogs down. The Monsoon’s custom tailored gear ratios act as torque multipliers to deliver even more power when you need it.
