    Tradewind. I have a 2002 GTX DI as well. Same color as yours. Bought is in 2010 for $3,500 USD and in was awesome for 10 hours and the engine seized tight. It had 145 hours on it at that point. I paid $1,700 for a new engine from SBT and rebuilt the pump and had the impeller reconditioned for about $100 in parts. I also bought a new oil injection pump for $235 after I pulled a nipple out of the old one. So the bottom line is I have a great running ski that is very good on gas for about $5,535. My kids love it, I love it. I guess that is all that matters. Good luck with your ski. Keep an eye out for the voltage regulator. They go bad frequently. The ski goes into limp mode and you get a 12V low message. I have the service manual. Let me know if you want it.

    By the way. 51-52 mph is the best you can expect without mods. If you ask me, that is fast enough if you let your kids use it.

    Latest is I think replacement of the fuel pump itself and the filter is on the cards for a bit more top end RPM, I think there is a deficiency there and pump doesnt sound as smooth as maybe it should. This is a bit of a deduction from when I added the fuel treatment and power was restored, so considering there will still be "stuff" in the filter and that pump now has 85hrs or so on it but more important a lot of years sitting in fuel that wasnt exactly pure. In fact is fuel ever very pure in a Jetski after a year or so??

    Apart from that we have been racking up the hrs on the machine and certainly getting plenty of fun for our hard work of fault finding

    All Good and DI is not to be feared as it seems to be, logical fault finding efforts will sort it out without hooking up to a dealer machine or having a dealer scalp your wallet.

    It's a bit early to be hitting the water here but we did last WE.

    The Di is running better than ever, I will probably change fuel pump and filter in a month or so.

    Really really pleased with the ski, worth all the original effort

    Update

    Been putting in a good few hrs in the ski of late, all ocean work and running most awesome ..................... until today

    Was planing along 2 up at 48mph for a fair while then a small reduction in power then complete engine stop - nothing on dash - just dead. Removed the DESS key and reattached and machine restarted immediately with no trouble codes etc. Very weird and we were a long way from anywhere in the Coral Sea. So, off we went again and after a short while same thing again, except a bit more progressive this time but still dropping power rapidly followed by a total stillness and a dash showing nothing, reset the DESS connection and away we go again - this time not going over 30mph went quite a bit further but eventually coming to a complete stop again. Then since were a damned long way from anywhere we fitted the training DESS key and resetarted again and motored along at 25mph - went a LONG way like this and got very close to land when again out it went - very hard to start and it seems like the fuel pump is running below its normal speed, much reduced hum. So after connecting and disconnect the DESS key many times finally the fuel pump noise pitch increased to more normal again and machine finally restarted, we motor on then back to the boat ramp and safely home. Scary stuff indeed!!

    So, to sum up, I think I am up for a fuel pump and filter, this items have been a bit iffy before but after a dose of fuel additive the ski has been great for ages, but the fact it responded to such so hugely must be an indication that there is some issue with either pump or filter or both. most likely both now we are up to 88hrs

    Otherwise it has been a real pleasure in the meantime

    Did change lubricant over the Mercury PWC stuff recently

    Fuel Filter replacement for DI models that have a one piece hose and filter assembly

    Like many others before me, you at some point want to replace the fuel filter and you find out its USD$150 or AUD$300 for the piece from the SEADOO dealer ripp-off merchants

    Here is the solution (many others have already done it but not shown how)

    The replacment filter is a RYCO Z200 or COOPER WZ200 - cost is AUD$11.00

    This fuel filter is common to the Australian made Holden (General Motors) Commodore VS series V6 (3.8 liter) engine car - Year model 1996 - 1999

    This starts off with the black (stock filter) and ends with the replacement Cooper filter installed. Pics tell more than a thousand words.

    I double clamped the hose both sides with high pressure fuel system clamps. Ski fired up after 5 secs of cranking and ran perfect!

    Someone should make up a little DI fuel filter kit using these parts and sell it.
