Advance ma100 gearbox

[Pdcruiser]

Hi I'm looking at replacing my gearbox on a 30ft sailboat, and have found a Chinese ma100 advance box does anybody have any reviews of
these.
Thanks in advance

I had a smaller model in Dufour sailboat that I owned and it never gave any trouble but it’s a nuisance finding a spot for the oil cooler. The MA100 weighs 75kg so that’s a big chunk of iron in a 30’ sailboat. If your engine is only a low hp type , consider a mechanical ZF/ Hurth, lightweight and easy to lift into place without a chainblock.
