Vetus M4.35 vs Yanmar 3JH40
The Vetus M4.35 is a 33 hp 4-cylinder marine diesel aimed at medium sailboats and powerboats, and a common alternative to the Yanmar 3JH40. The Vetus is a 4-cylinder and the Yanmar a 3-cylinder unit. The Yanmar rates slightly higher on paper (40 hp vs 33 hp), though both target similar vessels, so the real differences come down to mechanical versus electronic injection, weight and local support.
