4JH45CR propeller questions
What size propeller suits a Yanmar 4JH45CR?
It depends on the gearbox ratio behind it (documented installations most often run 2.49:1, 2.23:1, 2.36:1) and the boat it pushes. Power and max RPM set the optimum diameter; the ratio converts engine speed to shaft speed. The Builder runs the numbers and an engineer verifies.
Which propeller family do Yanmar 4JH45CR owners fit?
Documented Yanmar 4JH45CR installations run Varifold 3-blade, Autoprop H5 — the split follows boat type and usage rather than the engine itself.
Does the Yanmar 4JH45CR come in shaft and saildrive versions?
Both are documented: 15 shaft and 68 saildrive installations. The propeller differs (hub vs spline fitting) so tell us which yours is.
