    1998 Seadoo Challenger 1800 Won’t rev above 5k rpms

    No I don’t have anymore pictures of the carbs. Yes, next time we take it out I will pull the red wire on the rectifiers. All of the passages were clear but next time we take the carbs out I will check again. No, I did not change the fuel lines my self. I got them the way they were. The...

    1998 Seadoo Challenger 1800 Won’t rev above 5k rpms

    Yes. When I got the boat, it was running way better then it is now. So I know the dang thing will run. The reason I changed everything is because I was pointed towards doing a carb rebuild with Mikuni parts. Which I agree with. So I followed mikidymac’s carb rebuild thread. Replaced everything...

    The yellow hoses are feeding the fuel into the carbs. I always have the air boxes on, they were off for the pictures. You can see them on in the last picture. Yes, you are right about to being a 97, I was questioning that myself but never really bothered to go super in depth to find out because...

    Okay, I really doubt this is the problem but if you could send post pics of yours that would be helpful. The line could easily be cut shorter and routed different. But it’s not causing it to not have enough fuel. Thanks

    1998 Seadoo Challenger 1800 Won’t rev above 5k rpms

    Yes it has 1.5 needles and seat in it. I have checked MY rebuild work 3 times now (headbang). The previous owner did a rebuild on it but it was with an eBay kit, so I rebuilt them all my self. Second, yes my fuel line might be routed in a different way, but they both go right back to the fuel...

    1998 Seadoo Challenger 1800 Won’t rev above 5k rpms

    Well no I haven’t confirmed your questions about the fuel lines. I haven’t messed with it since. But, I know it was all working correctly a month ago and there was no problem at all. So I doubt the routing of the lines is the problem. Plus, I know it’s getting gas because if I pull the choke out...

    1998 Seadoo Challenger 1800 Won’t rev above 5k rpms

    Well yes and no. Replacing the rectifier did allow it to go above 7,000 rpms. BUT, only sometimes and only after the boat gets on plane. Second, I am sure my carbs are the originals, except for the oil injection is blocked off and the accelerator pumps were removed. But I know the fuel lines...

    Did you ever find the solution to your problem? I am having a similar symptom with my Challenger as well.

    1998 Seadoo Challenger 1800 Won’t rev above 5k rpms

    It’s not that the boat isn’t hitting peak rpms at 7k. It’s that there’s a hesitation before it gets on plane. Do you think that the raves are not shifting the HP curve early or late enough? I’ve been seeing so many posts about these boats having these rpm problems. With only one posting a...

    Does anyone have any info on the RAVE’s? Adjustments? If this could be the issue as well? Thanks

    1998 Seadoo Challenger 1800 Won’t rev above 5k rpms

    Okay so I haven’t been in town the past week so I’ve just been researching and thinking. I believe I will change out the jets. But, I have read many posts on here about the raves not opening up, or opening late. I cleaned all 4 and they all seemed okay with the slots in them. But, I had no idea...

    1998 Seadoo Challenger 1800 Won’t rev above 5k rpms

    WD-40 because that is what was suggested to perform the pop off pressure test. Just decided to use it to make sure the airways were open. Second, yes, I don’t believe it was rejetted-maybe it was idk. But what’s pilot jet should I order? Where to order? Yes I have twin 787 engines. I was told...

    1998 Seadoo Challenger 1800 Won’t rev above 5k rpms

    Okay. But yes we flushed wd-40 through the by pass ports and they were not plugged. Second, yes we did check the pop off. We set all of them around 30-32 psi. Yes I do have the stock air boxes installed. My other question I’m confused out. You mentioned that a high or low pop off pressure...
