Hunter 376 transmission gear ratio

[Ed.S]

Can anyone tell me what the gear ratio is on a hunter 376 with a KANZAKI transmission with a 3JH2E engine.

Yanmar datasheet attached indicates the transmission is a Kanzaki KM3A and gear ratios tabulated below from this reference Marine Gear; Applicability Of Marine Gear And Reduction Ratio - Yanmar 3JH2 Series Service Manual [Page 13] | ManualsLib or YANMAR 3JH2E 3JH2TE Marine Diesel Engine Workshop Manual (emanualonline.com). Might have to cannot your local Yanmar dealer Marine Diesel Engines and Marine Engine Parts | Ace Marine Diesel, FL to confirm your transmission gear ration based on its serical number.

Thank you, that helps. I'm trying to determine what folding propeller to use.

There should be a small plate on the case with the ratio stenciled on it. A mirror and flashlight may be needed.

Thank you, I found it.
