I have been running the Hydradrive leg for 2 years with no problems. OK, so I'm running it on the 4 cylnider 370 sti, but it is the most wonderful leg I've ever used. I drive a lot of boats during the course of a year, mainly with either Volvo or Mercruiser legs - when I get back on my own boat it is such a pleasure not to have to wait for the grinding or cruching - I LOVE MY LEG!!!
I would spec any boat now with Yamaha, my 370 is now on 920 hours, it is not even run in!
It starts first time every time, it runs like a dream with no smoke and I can talk at normal voice when at the helm. It's economical - 0.8 litres/nm. There is no massive turbo lag as on the Yanmar - bugger all happens up to about 2.5 k revs then turbo kicks in and it leaps of liek a scolded rabbit - part of the reason why the Bravo 3 has suffered, particularly with the 315!
I'm a Yamaha convert, as far as I'm concerened it's the only engine/drive package to have.
