    2007 RXT 215 - P0344 Code - Need help! PLEASE!

    Help! I have bought a 2007 RXT 215 that spun the #1 main and burnt the rod bearing. Unfortunately, I have no history on the ski past that, other than it has 236 hours on it. I rebuilt the supercharger (using Riva Washers), replaced the short block with one out of a 2005 RXP (using new ARP head studs and new OE rocker bolts, flywheel bolts, etc.) and reused the top end / flywheel / rear cover off the 2007 engine. I did replace all the valves in the head as well, to be safe.

    I have re-installed the engine, but the engine will not fire, giving me a P0344 code (cam phase signal missing). I put a new cam sensor in it, but that did not fix the issue. Traced all wires and everything ohm'ed out fine. I also cleaned every ground I could find. I did recheck to make sure the timing chain was intact and the cam is truly spinning - it is.

    After exhausting all my resources, I took the ski to the local Seadoo dealer to plug in B.U.D.S system to see if there were more codes that may give a hint of what the issue is. The dealer did not find any other codes relative to this. They also traced the harnesses, changed the cam sensor (again) and replaced the ECM. None of this changed the situation - still getting the the same P0344 code when cranking. The dealer gave up, but said they feel the issue is with the flywheel, but could not explain how that could be as it is giving a cam error, not a crank signal error.

    The flywheel and trigger wheel is doweled, so I don't think I assembled that incorrectly, but maybe I missed something. Before I pull the engine back out to check the flywheel installation, does anyone have other suggestions to look at? Could the cam sprocket be bad, not triggering the sensor? I assembled the head and installed the cam according to the manual, using the locking pins. It has about 130 psi cranking on all cylinders, so mechanically, I believe it to be sound.

    I would greatly appreciate any suggestions!

    From research i have done you may have used the wrong pto housing or incorrect cam gear or flywheel when you assembled the motor. I would make sure you have the correct timing set on your flywheel check this thread

    Also this thread for differences that need to be changed. I believe you have to drill a hole in the block for the crankcase vent differences between a 2005 and 2007 block.

    Thanks for the quick response and information! Much appreciated! Sounds like I will be pulling her out this weekend to dig a bit deeper! The flywheel, cam gear, and housing is all from the 2007 block but the crank is obviously from the 2005. Do you have a suggestion the best way to marry these parts up? Could I swap out to a 2005 cover to make it all work or is the flywheel different as well, do you know?

    Thanks again...

    Your going to have to take the 07 crankshaft, and crank trigger cup along with the 2007 PTO cover and transfer that stuff into that 05 block. OR, I believe you can remove the locating pin on the 2005 crankshaft and move it counter clockwise so the trigger cup is now reading the crankshaft as an 07. I have heard some people say this works and some others say no, but I don't see why it wouldn't work.

    Slow 91. Yeah...the 2007 crank is killed, so I will have to replace it with a 2006 unit and up or do as you suggest and try to relocate the locating pin. That's a great idea, so I will work on that and let you know how it goes. I assume the gear is pressed on, wonder if I can heat it and turn it. Do you know if the gear / crank is keyed or splined?

    you don't have to remove the gear, just the pin. take your 07 crank and put it next to the 05. both #3 rod journals at top dead center, the 05 crank will have the pin at the 12 oclock position and the 07 pin will be at the 7 oclock position. remove the pin from the 05 crank, and rotate the crank trigger cup until the hole for the pin is in the same location as the 07 crank.

    Pulling the pin and rotating the trigger will *somewhat* work. It isn't optimal, as there is about 7 degrees of crank error when you do this, as the pins are not in the same relative position to the bolt holes.

    See this thread I started awhile back on this topic:

    http://www.greenhulk.net/forums/showthread.php?t=147773

    The reason it will work with this much error is because the ECU does a dynamic timing adjustment. As far as I know, nobody has researched what liability you might have by introducing this much timing error, probably only an issue if you have bad gas as the ECU will have a skewed range of compensation.

    Thanks to everyone on helping me with this issue - lots of good info!

    Rotating the trigger wheel certainly seems to be the easiest fix, but I am concerned about being 7' low on timing. I got in touch with the guy that I bought the 2005 block from and he still has the PTO cover. He only wants $125 for it. I think that might the the safer bet, assuming all the 2007 parts (flywheel, trigger wheel, etc.) will work. Does anyone know if there are any other pitfalls by changing the PTO cover to the 2005 unit? Thanks again for all the help!
