Three different versions of this vessel were manufactured by CSY. The Mid Cockpit model is the most popular. Originally designed for charter service in the Caribbean, the robust construction of the CSY 44 provides a solid and roomy vessel for cruising and live aboard. Arguably one of the most ‘over built’ of all production boats ever made we are assured that CSY 44 will be around for a long time to come.

Related Models

The CSY 44 was only in production for about 5 years.

  • Walk Through version.
  • Pilot House version.

The CSY 44 will most likely have a Perkins 4.154 as original power using the extremely dependable Velvet Drive transmission in a deep gear reduction.

Repower Recommendations

The Beta 60 with a Velvet Drive adapter kit has proven time and time again to be the perfect replacement engine for the CSY 44. This engine provides the high torque and low 2700 RPM maximum operating speed that works perfectly with the original Velvet Drive transmission and prop shaft arrangement.

Naturally aspirated and all mechanical fuel injection make this powerful diesel a trouble free addition to your cruising experience. With no turbocharger heat and noise and no ‘black box’ computer engine controls, the Beta 60 is EPA rated for all applications.

Reusing the original Velvet Drive transmission is economical in many ways. It is very inexpensive to rebuild this transmission to like new condition and installation is simplified by using the original mounts that are fit to the side of the transmission case. With a 2.91:1 gear ratio, it will turn a 24” diameter propeller in the same rotation as the Perkins 4.154.

Beta Marine offers 22” wide mounts that work well for replacement of the 4.154 Perkins. Please call us to discuss your current installation and the best repower options.

Installation Considerations
Things to Know
  • The Beta Marine stainless steel high rise exhaust elbow is used and can be easily modified if required.
  • Turbo charged engines require 3” or larger exhaust diameter. As the Beta 60 uses 2” exhaust, you will not be required to redesign and rebuild the entire exhaust system.
  • Please call and ask about our Velvet Drive adapter kit engines. We can also arrange a reconditioning of the current Velvet Drive gear or supply a new unit.
