Hi Fitzy, Depending on the total displacement you may also be able to have the non-turbo versions on 54/55 hp. I like the Volvo since it has lower revs and of course also since it is a Swedish brand But otherwise I think you should buy where you get good service and Yanmar use to build very reliable engines. I have good experiences from both brands, although not this size of engines, only smaller and bigger.
Hi Total displacement is 20 ton. from my enquires spares of yanmar are cheaper (filters) regards fitzy2 in cape town
Yanmar Hi Fritz As a delivery skipper Ive sailed/motored many many miles (150000) and Yanmar engined beat Volvo hands down . 1/ Yamnar engines are smoother. In fact 7 out of 10 times I can tell what engine is installed by the vibration 2/ yanmar engines use less fuel , as I said if motored many miles and as adelivery skipper I have to pay for the fuel used so I pay particular attention to fuel usage , and the Volvos defineatly use more fuel . Im talking about the same types of yachts at the same speeds and the same revs The last boat a new 55 ft with a Yanmar used 2.2l/hrs the same boat with Volvos got 2.9l/hr Remember we were delivering and motorsailing so after 3000 miles worked out the averages for both trips On 40 ft Catermarans the fuel for Volvo 1.8 and Yanmar 1.3 l/hr With regard to filters dont buy "factory " units You can get premium quality filters from automobile spares suppliers ie Yanmar filters are the same filters that are used in Mazda ,Toyota and Honda cars at a 1/4 of the price as factory parts . Volvo filters both diesel and oil ,aswell as bets are available from Auto spares outlets , just select reputable filter manufactures Clive
definately Yanmar for me. I've had nothing but trouble with Volvo but have thousands of miles with different Yanmars without a single problem. They go forever!
I work on marine diesels all day long and it seems that all I seem to fix are volvos my choice would definatly be yanmar
I would stay AWAY from Volvo....parts are expensive, service is poor (in the US anyway). The Yanmar will outlast a Volvo by far and be less expensive to service when required. Yanmar without a reservation. Dave
Hi, After having been exposed to various flavours of Volvo KAD 44, KAD 44E and an older TAMD 6 Cyl Engine with separate cylinder heads over the years I think I can say I have seen a lot of what they have to offer in problems. I am currently using 3 Yanmar 315 HP, 6LPA-STZP Engines in two tenders, one in front of a Hamilton Jet and the other two on Mercury Bravo 3 Stern Drives. I asked around a lot before making up my mind and hope now that these Engines and Drives are as reliable as I have been led to believe they will be
