Testing Cox CXO300 Diesel Outboards

what's going on Captain Bill and I only just completed our test of these two outboard cheer it's certainly today at first huh yeah yeah now I know this is a test we were both looking forward to for quite some time since these engines debuted last year's Loren Dale show we've been excited for this for for a lot of reasons but we've been discussing the possible benefits of the diesel outboards whatever a couple that jump off at you well probably the one of the biggest ones is that you can have a tender on a mega yacht and use diesel fuel you don't have to have a separate fuel on the on the vessel right pretty much same thing for military vessels so that's that's good you also get more torque diesel little famous rhetoric and that manifests I think in efficiency we got pretty good mid-range especially kind numbers recently about 3,000 rpm we're burning about 17 gallons an hour okay for a about 1.8 miles per gallon which is really good I'd say for an outboard powered boat now in a 14,000 pound boat right I think that's true but you know bill I think I think with this one dad only tells part of the story give me a sense of what it was what the feeling of like was at the helm what it sounds like would it smell like well I was wondering would this smell like a diesel didn't it doesn't i think that's gonna disappoint some people yeah but I never caught a whiff and at the helm it this boat performed pretty much like a gasoline-powered boat I don't know that I would have known I was driving a diesel power go other than when you turn this boat you know in a hard overturn it doesn't I couldn't detect and the instrumentation this is a prototype boat the instrumentation is a little imprecise so I couldn't really tell if the RPMs were dropping or not but it my ear told me that when I turned a hard over turn I was not losing any rpm at all I think because of that torque situation right and about the sound we were noticing that it wasn't it certainly isn't the quietest outboard on there on the market because let's be honest some of these newer engines are getting whisper-quiet these days but but really was it was pretty competitive and it had kind of a nice deep pitch to it didn't have any of that wine we've heard another output even when the turbos kicked in right yeah and I thought it's comparatively noisy at the low rpm in the upper register I don't think there's much difference at all now that's that's good point yeah what now anytime you have a new propulsion package that's this radical and this different there's there's gonna be some doubters out there so it for the sake of our readers what might some possible downsides be well the biggie of course is cause what they're telling us is that this particular engine is gonna cost $50,000 right that's significantly more than what you pay for a gasoline-powered outboard of the same horsepower right then the weight issue and I was concerned about that myself I was afraid when we took it out in the river st. Johns River we were gonna have a bow high situation because of all this weight yeah extra 400 pounds bags and versus gasoline outboards right but did not notice that at wide open throttle or 3600 rpm which the engines are governed at at the present time because their prototype engines we were getting 2 degrees which is optimum for planing boat yeah I mean I'd be curious because that was a good point I had the same concern I wonder what it would be like if we're on a lighter boat maybe a rib that's just good instead of a 14,000 pound intrepid yeah yeah but no I would say you know if we were blindfolded at the helm which is never a good way to drive no you wouldn't you I didn't think we wouldn't think there was any difference no no but one of the things that was concerning me a little bit was especially at the onset was the ability to get these engines service if you were an early adopter but kinda we learned today that you know Cox really already has a pretty good distribution network kind of around the country and that those guys are being trained up to be able to offer the service now ring power will train all the technicians that serviced this in their service this engine they'll train them at their facility in st. Augustine and it sounds like quite a facility it sounds like they're going to do it and then those guys those people will go out all over North America and but you know ultimately I think there's probably gonna be a learning curve I mean there's no way out of that right and I think you know take a little bit of time I mean it's not gonna be compromised all to the service you can get say from mercury Suzuki but they seem to be taking the right steps towards that yeah they do yeah well bill I know with the story like this he kind of be complex I know this you have to go back and we need you to do a lot number crunching so you want stay tuned to an upcoming issue of power motor yacht or outboard magazine for captain Bill's full report yeah but why don't we get lunch you need a lunch break yeah I mean geez Dan come on all right all right let's go get some lunch I think they said something about a nice barbecue you always find a good barbecue spots
