This is the main problem with people thinking a service is just oil and filter lol, yes any fool should be able to do this but it seems some can’t and over fill or under fill so it must be harder than you thought
Maintenance/Service means they check things that need to be checked and then let you know and tell you how much ot will cost to change, you also get a warranty when they do it rather than if you do.
If you read through these forums and see how many people have trouble after their expertise fails as you all think it’s so easy as why on Earth would anyone need to do an apprenticeship or train to work on small engines and the Electronics that go with them.
I am an expert in my fields and would never go onto a Forum that has to do with repairing Electronics that I do with the proper equipment and in clean rooms, no expert will tell someone to do it themselves as the amount of tools needed for most post 2000 vehicles is not just a Screwdriver and Shifter.
Did you have any equipment to connect to your Computer system to see if it was running as it should, if the injectors were working correctly as you may not have re-connected the fuel system correctly and end up with insufficient fuel and this could also cause lower revs and less power, dirty fuel and fuel injectors getting clogged slowly over time causing a couple K slow down per year ?
Fuel filters, fuel lines, air leaks, pressure tests, I could go on about all the hundreds of simple things a non expert could cause without even knowing and to not even be able to test anything other than put it together and take it for a ride lol.
What you need to do is have a look in a Jet Ski workshop one day and see all the equipment and how they test a Ski to see what could be wrong and then you may understand why I make the comments I do about self service. Your saving of the couple hundred dollars didn’t really save you anything now did it Maybe Pray for it next time as it at least would have kept going and did you read the hour meter to see how many hours it had done rather than say how old it was My 2008 SC 1800 Yamaha has only done 310 hours as we have a few Skis, I wouldn’t have bought a Ski if I couldn’t afford to look after it, would you do your own servicing on your Vehicle ?
I have the expertise to be able to do everything required on a new Vehicle let alone a 10 + year old Ski, trouble is expertise doesn’t equate to having the equipment to do it, the cost of a Maptuner X isn’t that much about $400 and the License for your Ski only another $500 and at least you can Tune your Ski.
Just curious besides the thought that the Ski was old how did you determine the SC needed to be refurbished ?
People never like facts or being told just how not great they are at some things and when they stuff up its always everyones fault other then theirs.
I take my items in to a professional as then not only do I get it back the same or next day but I know I won’t have to swim back to shore because I made a mistake, I also know if the Ski sinks or my Vehicles burst into flame my Insurance will pay me out to replace the item, if I did it myself with out the certifications to be qualified then I threw my money away, also if some one was hurt. like say your 16 year old daughter riding the Ski and it blew up or sank while she was way out or it wouldn’t stop and went flat out and ran her into a pilon or another boat, how much would the $200 saving be worth then.
Any way my two cents , eventually everyone either trieds to pass off their self worked item onto some other poor sucker or they take it to an expert and try to BS that it’s how they bought it rather then say yes I did this to save money ROFL, call me a troll if you like but it was you that did your Ski not me and I never gave you bad advice to do it yourself so blame the others that did and listen to sense next time
