Comments

A popular Robert Perry creation from the 1980’s, this vessel shares the same cruising fin keel and skeg hung rudder as the Valiant 40. It is a very successful design that has proved to be a capable cruiser without giving up sailing ability.

Related Models

Valiant 40, Baba 40, both Robert Perry designs.

Power

The Perkins 4.108 was most commonly used. Mercedes and Pathfinder also used.

Repower Recommendations

The Beta 43 and Beta 50 have been the go to engine replacement for the Passport 40. The Passport 40 propeller diameter is limited to 17’-18”. The Beta 43 or 50 with a 2:1 gear reduction works well with this propeller size and does not over power the available blade area.

These naturally aspirated and all mechanical fuel injection engines provide trouble free operation. The low RPM operating range provides quiet power and fuel economy. With no turbocharger heat and noise, the Beta engine works very well in the confines of the rather tight Passport 40 mid-ship engine box.

Beta Marine offers 22” wide mounts that sometimes works well for replacement of the 4.108 Perkins. The standard Beta mounts also work well for Pathfinder replacements. Alternatively, the Beta Marine custom mounts may be the option that will make installation as easy as possible and with no modifications to the existing engine beds.

Installation Considerations
Things to Know
  • The Beta Marine stainless steel high rise exhaust elbow is used and easily modified to point towards the starboard side of the engine box. These elbows never rust or require cleaning.
  • Unlike turbo charged engines that require 3” or larger exhaust diameter. The Beta 50 uses 2” exhaust. This means you will not be required to redesign and rebuild the entire exhaust system.
  • While the standard oil filter and raw water pump configuration provide good access for maintenance, a remote oil filter kit is also available.
