2001 Seadoo GTX - Surging at Full Throttle, Bogging from Idle

[bj_pwc]

Yesterday I took my 2001 Seadoo GTX (model 5527, carbureted) to the lake and was having some surging at full throttle as well as bogging when trying to get going from idle. I thought some of this could be related to old gas (has sat about a year since last run, sat at least a year prior to that). After some research on these forums it looks like I have the gray fuel lines which may have led to clogging the carburetors.

Does this sound likely?

Today I siphoned out all the remaining old fuel. While I was at it I unscrewed the fuel filter and noticed lots of sediment (grey colored...maybe fuel line?).

So at this point I'm trying to determine whether or not this is something that I want to attempt to fix myself or if I want to take it somewhere.

If I were to fix it myself, where is the best place to purchase parts? I know I can get the fuel line and clamps from my local autoparts store. How much fuel line and what size do I need? Where can I buy the carb rebuild kits? What about the fuel selector valve? While I've got the carbs off, anything else I should do? Is there anything to clean/replace with the fuel pump?

If I were to decide to take it somewhere, does anyone know of a quality shop in Houston, Texas? I live in Katy (far west side of Houston), so the closer the better but I want a quality shop that isn't going to rip me off. Any guesstimates on how much this work would cost?

Thanks in advance!

If it was me, I would replace the fuel lines and clean everything else in and out (including carb). I would use the old fuel lines to know how much new fuel line to get. There was 2 different sizes for my seadoos. Fuel size and vent size. (parts take a long time to get to me and they are super expensive locally so I tend to avoid new parts unless necessary).

Others will tell you to do the carb kit at the same time and replace both the fuel selector and fuel filter.

I think someone said $600us the other day, but that might be something different.

No idea about shops in your area.

Thank you for the reply.

I would prefer to have new fuel hose available so that I can remove one hose at a time, measure, cut and re-install. Does anyone know the size(s) and length(s) of fuel hose required?

I was trying to trace the fuel lines last night and it looks like the best way (or only way) to replace them will be to remove quite a bit of parts first. Like the exhaust, intake, possibly carbs... Am I looking at this wrong? If I'm pulling off the carbs, I might as well rebuild them.

Other than parts, what specialty tools am I going to need? Looks like something to measure the pop off pressures, what else?

Thanks!

Too many questions?

a) This will be different to different seadoo's. I just found it easier to remove them first, measure up, add 2 feet for safety then buy it. I have done 2 similar seadoos and I can't remember. I have to do 2 more similar seadoo's by this weekend (would have been nice if I kept the order around). I have finally convinced some family members to get their grey fuel lines removed.

b) You don't neeeed to take off the exhaust as far as I know (but it would make it easier for the first time in there), but the rest you do, and possibly even remove the tank (but I had to fix my fuel sending unit when I did mine, so it might not need to come out). If you are having fuel problems, at the very least you should be taking a look at the carbs inside. Keep note, you can take the throttle/oil pump cable attachment off the carb to not lose the adjustment settings.

c) I don't remember requiring any special tools. If you take the exhaust off, I like to seal it with the high temp copper gasket maker. The pop test would need a pressure gauge. While the pop-test isn't required, it definitely helps to do while doing it incase something doesn't work.
