    300hp diesel outboard

    They look impressive, but no mention of price and weight!

    Been around for ages now, cost a fortune, and weigh a ton.

    could these mark the end of the inboard diesels. would be costly first up but would do a million hours if serviced routinely.

    doubt it

    compromises always get made to package a engine in a outboard
    most would be work boats as any 300hp sized pleasure craft would wan maximum deck space and duck board size
    would there be more efficiency with a shaft and rudder then dragging a leg through the water ?

    Re: 300hp diesel outboard

    good point about efficiency, what about weight difference between the two .

    TBH I've never understood the fascination with outboards over inboards here...especially with some of the huge rigs getting around. IMHO they lack the class of a V8 petrol or 4/6 cyl diesel setup.
    Yeah you lose some deck space but it gives you a nice table for your gin and tonic. Probably showing my age.

    There are several breeds of big diesel outboards around now
    Got me stuffed why they don't look at the smaller sized range.

    Tuna because they are utilising car engines

    all modern outboards are some variation of a car engine so whats they are using car engines got to do with the conversation (well except the etecs)

    a diesel outboard is in a less unsulated noise space
    big boats have plenty of room under the deck for more insulation seperate cooling systems and so on

    just different uses.
    Diesel outboards offer some rather unique range and single fuel benifits that petrol dont at this stage. that and torque.
    The boat we are building is to be paired with a larger mothership based out of NZ. which will carry 9000lt of diesel. so as a single fuel mothership it makes sense to have diesel outboards

    We run diesel outboards at work. They're a mercury 175hp.
    They're absolute rubbish......
    They're a 2 stroke, spark plug diesel believe it or not. They're a prick to start, smoky as all #### and thirsty.......
    Only reason we run them is so we don't need to take separate ULP.

    We borrowed them off the navy, wondered why navy would give us free boats, found out why pretty quickly.

    It's basically an optimax, converted to run on low sulphur diesel. they say it shares 95% of the parts from the petrol optimax.
    interesting tecnology, if you'd call it that......LOL
