Related Models

As usual with most of the Catalina lines, there are variations to the Catalina 36:

  • The MK I version began in 1982.
  • The Mark II version began in 1994.

The Catalina 36 was available with standard fin keel or a shoal draft wing design.


Original builds from 1982 started with 23 hp diesel engines as standard. Later in this model’s history, the 36 Mk II was fitted out with up to a 35 hp engine.

Repower Recommendations

The Beta 30 is a fine replacement engine for the Catalina 36. It produces the power you need for motoring and low speed handling, while also providing excellent efficiency. The Beta 30 fits the engine compartment very nicely and the exhaust is properly located on the port side of the engine. This is important for easy installation when using the original Catalina muffler location and design. The Beta 25 has also been a common engine replacement for the Catalina 36.

Beta Marine standard mounts are typically used to repower the Catalina 36. Please call us to discuss your current installation and the best repower options.

Installation Considerations
Things to Know
  • As with many Catalina sailboats, the 36 has exhaust routing that is somewhat unique. We have the information and parts you need to make sure the exhaust is installed in the safest, most effective and cost efficient manner.
  • The Catalina 36 is a cruiser that sails, the larger 120 amp Beta alternator, Deluxe Control Panel, and water heater connections are popular cruising options.
  • In order to maintain full sailing potential, the J-prop feathering propeller has become a welcome addition to this repower package.
