Sabre was an English co that bought the ford engines and marinized them their own way. Same basic engine as a Lehman, but many of the bolt on components are unique. Sabre was not associated with Lehman, they just shared the source of their basic engines.
What hp is engine? The high hp ones are probably trouble. 120hp six probably ok as coolers could be adapted to Lehman style. 275hp probably a PITA.
