Convert 2003 8.1s Merc to DTS?

[scottgoad]

I have a 2003 SeaRay 340 with twin Merc 8.1s v-drive engines with SmartCraft. It appears that the DTS was an option, but I don't see anything about making a conversion after the fact.

Is this do-able? If so, is it even worth it? I like the DTS controllers, engine sync, etc.

Thanks!

Hello I don't believe you can I don't think they offer a kit this is what I found

Can I convert my mechanical engine to DTS?
We do not offer a kit to do this modification and buying individual components to accomplish this is cost-prohibitive.* We cannot help you modify your engine.* Damage caused by product modifications is not covered by the limited factory warranty.

I hope his helPs that's from the merc sight

Here would be a start to help you give you an idea of what would be needed to change over.

But now as I look a little further into this,
Usually when a command module was to be installed up near the helm it would require the adaptation of the electronic remote control (ERC) levers using the Mercury computer diagnostic system (CDS). The command module is used to communicate with the new PCM you may need back on the engine, so you would need a mercruiser dealer with CDS to synchronize the system.

Mainstream, here's what they really should have told you, But as you know it's just easier to say we do not offer a kit to do this modification. Especially when you need to hold a special certification just to be able to retrieve a package part number as a starting point.

The Digital Throttle and Shift (DTS) System The DTS system is a complete and tested control system. It is comprised of multiple modules that have specific software in them. Each module has to work correctly with all the other modules in the system. Mixing and matching of components is not recommended. Mercury ships the components as a package, and the package needs to remain together.

DTS Certification Vessel manufacturers are required to complete a certification program before producing DTS equipped vessels. Compliance with the information contained in the certification document is required for production purchasing of DTS propulsion packages from Mercury Marine. The intent of the certification is to define a procedure that will ensure the OEM is cognizant of the functionally, means of installation and calibration of the system. This will ensure safe operation, reliability, quality and functionality of the system.

It's amazing what is "do-able" if you throw enough $$$ at it! The bigger question is what is the "gain" factor in DTS??

I have seen DTS shifter/throttles and other DTS related parts listed on ebay motors from time to time, but as said earlier, getting all the parts + getting them properly calibrated will possibly involve more steps than you may want.

I must admit going from an 02 300 dancer which was mechanical to the new dts was huge they are smoother operating also you can control both engines with one lever while cruising they auto sync around the dock you can use two fingers to maneuver and you can lock them in docking mode so they don't go over 600 rpms so you don't toss any one over the side while they are getting ready to tie up the cruise control is cool to just sit back and enjoy no messing with throttles due to currents or sea condition so there is alot to gain but I don't think. Pouring huge dollars at for a retrofit would be worth it but on a new buy or upgrading boat it's nice to have just my $.02

I really can't imagine smoother shifting or throttle action than I have now (it's non DTS) and although I cannot control both engines with one single throttle, my two throttles are only 1/2" apart anyway so I just grab the pair in one hand. There's no docking mode, but with the torque from the 8.1's and 4 bladed props it is a rare day where the throttles even need to be touched. In the event that one does need some gas, the throttles are very smooth and progressive so over reving has never been an issue. I did cheat by installing "Accusync" for a few hundred bucks which ensures both engines run at the same RPM with a simple flip of the sync switch on the dash - no more messing with throttles based on sea conditions or currents which is very nice, but you don't need the expense of DTS to have this great feature.

I've had I/O boats with traditional controls and see where DTS controls are a huge improvement on that design. Anyone know just how much DTS adds to a typical twin engine setup?
