What do we know about Bat-mo-boat?

Thanks Dom and Timmy!, I guess turbo lag would suck when your trying to teach someone to get up, real slow acceleration and then BAM, rip your arms off.

Fit a low speed turbo, and a high speed turbo. What about supercharging??

Adds to the cost of the engine and makes it impractical.

Ford does that with their newer diesels, could be possible. Superchargers, sure, that's where the 6-71/8-71 blowers are originally from is Detroit Diesel semi-truck engines. Not sure how they would hold up running constant high rpm's.

In the testing that I watched with a major diesel company with MC and Nautique the biggest obsticle was getting the boat dialed in to its torque, there is no linear accelleration with the turbo diesel and you cant compare it to your truck, as far as fuel economy you can bet all you want but the numbers werent there, and with the up and comeing direct injected gas engines there fuel and torque is rivaling the diesel.

I forgot about this but that is the exact issue we've had with the turbo diesel Navy zodiacs. They are a 6 cylinder Volvo turbo diesel. At sea level they are okay but when you get then inland at altitude the boat won't hit boost till 22kts then WATCH OUT. It will knock you flat on your ***. They ended up switching to supercharged four cylinders because of this.

In the end you would need to build a custom engine for pleasure craft. Very doable but without the infrastructure to get the fuel on the lake, it wouldn't sell.

Didn't someone post a thread about a 2006 Mastercraft diesel for sale on ebay? It was a test boat they gave up on.

There was a guy on Wakeworld that put a diesel in his Epic too.

and tier 5 is not even fully written yet and wont take effect till after 2015 there guy who does developing lol

Tier 4 Standards. On May 11, 2004, EPA signed the final rule introducing Tier 4 emission standards, which are phased-in over the period of 2008-2015 [2786]. The Tier 4 standards require that emissions of PM and NOx be further reduced by about 90%. Such emission reductions can be achieved through the use of control technologies—including advanced exhaust gas aftertreatment—similar to those required by the 2007-2010 standards for highway engines.

Listen Chief Im all for Diesel as much as you. I love diesels, I wish the US market was as thrilled about them as much as you and I. It simply comes to money when companies make decisions. If it were that easy or most importantly CHEAP there would be a diesel option. To have any diesel engine in an inboard boat would be a task for money sake. Tier 4 emissions with a DPF/DOC and then to have it be a water cooled design could easily cost $12k just for the aftertreatment system.....this doesnt include the cost for the engine. A standard exhaust on a 07-10 Duramax/powerstroke/cummins light duty pickup cost each OEM about $4500. If you want to debate this thats fine. I have been designining/engineering and selling these systems with the OEMs now for over 8 years. They are manufacturing to much higher volume then any marine application. Typical prototype cost for an aftertreatment system for automotive is 3X production cost.....this is aprox $13,500. A water cooled design is much much more expensive. We deal with this on large diesel marine systems and the costs are very high.

^^^^ wow you are clueless Ive been working with Dpfs that passively regen as cool as 300 degrees .. Cool news here
