Also Volvos are heavier than Yanmars, not good in a RIB.
If thats the whole argument -- then its a crap one -- volvo's must be all of 60KG heavier than the yanmar - if that amount of weight effects the size of boat these are in then your boat is full of water...
and i do not think it is the engine, its the leg - i know of people that have been through 9 legs in a season with the Bravo 3, and a few that have had probs with the yam legs too -- (all commercial right enough)
Not good in a RIB -- mine go great, with allot more lard aboard than most --
Servicing is high with all these beasts, its something you will have to live with if you can afford to buy the whole thing.
My volvo's have been fine -- only wear and tear - on one i have 4000 hours on -- and was still going fine - but have just replaced it with a new one on the basis that reliabilty, is a huge factor for me, and i knew i would have to around these hours - -name me a yanmar with these hours on.
