here the response to an e-mail that I sent to Idmar...... <BR> <BR>"I am happy to hear you love your Hammerhead ... it is my favorite <BR>engine of all the engines we build. <BR> <BR>It would be pretty impractical to convert your engine to the ETX CAT <BR>system. Of course the manifolds and exhaust outlets would have to <BR>change but you would also have to change the engine wiring harness and <BR> <BR>the computer that runs the engine. There are also some additional <BR>sensors and some other components that would need to be added to the <BR>engine. Another major problem would be that the 2008 vintage computer <BR>that runs the engine is not compatible with the 2007 computer in your <BR>boat that runs the dashboard etc. By the time you would get it all to <BR>work you would have a significant amount of time and money invested <BR>that I am not sure would be worth the <BR>hassle." <BR> <BR>Larry Engelbert <BR>IndmarService <BR> <BR> <BR>Quoting Cliff <BR> <BR>> Hello <BR>> I have a 2007 Malibu VLX with the HammerHead engine. <BR>> First off, I would like to thank You guys....I love the engine! <BR>> However, the Etx-Cat system was not available on the HammerHead when I bought mine. <BR>> Is it possible to add it on now? <BR>> I am pretty handy with a wrench, or my dealer at Waterski America <BR>> would be glad to help. <BR>> Is it just a matter of changing manifolds, or is the engine brain <BR>> and wiring harness different? <BR>> would I need to modify the engine compartment? <BR>> thanks for the help <BR>> Cliff

MY ? Is why would you want to?

well Kevin, the hammerhead puts out alot of exhaust .....especially at surfing weights <BR> <BR>lots more than my monsoon did on my 2005 <BR> <BR>not so much that I regret the engine choice, but <BR>if it would have been a matter of switching manifolds, I would have done it <BR> <BR>an operation that could have been done in an afternoon <BR> <BR>that, however, doesn't seem to be the case

why not add a FAE system ? it would be a lot easier ?

thought about it clubmyke <BR>and I just might

I would like to hear from some 'Bu owners with the FAE system <BR>do yall like it <BR>does it work well with the power wedge? <BR>pics?

I thought the wedge had to remain down all the time to use tha AFE, and that would suck??

I think that FAE is in the process of designing a system that can work with the wedge on. I don't know if they have it finalized yet. If you don't have the wedge there is no problem.
