Anyone with hard mounts care to comment on 6 cyl or Perkins
cant comment on perkins per se, but if you are designing, one thing i think might be worth mentioning is the distance between g.box mount and fwd stern gland - on my boat more than a metre, and the stern tube is pretty long too - i'm just suggesting it might be worth thinking about or discussing with someone with experience in hard mounted engine
systems. I would say in relation to a 6 cyl engine
- properly tuned it has to be a lot smoother than a 30 year old 2 cyl., but even my old 2 cyl only produces negligible vibrations - and that in a fibreglass hull
