Hi John and Deb, this is Howard from s/v Jazz, Maramu #144.

We just finished a 3 1/2 year refit (restoration, really) of our Maramu which included repowering with a 75HP Yanmar 4JH4-TE. If you go to the Photos section, look for the album sv JAZZ which documents the entire process. There are several photos of the engine installation. You might also consider replacing the stuffing box with a dripless unit (we used a Tides Marine) and a large alternator (ours is a Bomar 210 amp that mounts directly to the engine with a kit made expressly for the Yanmar by a company called Altmount). Because the Yanmar puts out 13 more horsepower than the original Perkins we also went up an inch in size on our Maxprop.

Regards,
Howard Berger
