I went with a beta 60 with the tmc260 at 2.45 ratio, in a super maramu happy, I think you will be too

Dirk I did a refit on a Maramu hull 177 of a yanmar and used the original transmission. I can send picture if you want them.

Dear Amel friends, On our Amel Maramu hull 171 construction year 1985 the engine needs to be replaced. Our choice is a Beta 60. I've been configuring the motor for a week now. But unfortunately I can't figure it out myself. One says this and the other says that, in short, I have completely lost the thread. Which gearbox should I choose and with what ratio? My advisor in Holland says that I should go for a ZF25 hydraulic or a PRM 280 Hydraulic and my mechanic in France says that I should go for a mechanical ZF25 so that I can then tighten the prop. I am curious which gearbox and with what ratio you think best suits my Amel Maramu with a Beta 60 engine.
