97 Seadoo speedster jet boat both engines crank only one revs up with throttle

[marionr26]

Just drained my tank filled up with 93 octance gas I pulled all the plugs cranked motor no oil coming out the hole all new 4 plugs.

I cranked up my right engine meaning the right start button it cranked i gave it the throttle I could here it rev up good. I shut it off. I cranked up the left engine meaning the left start button it cranked up it didnt sound as lound as the right engine so then i gave it throttle and it didnt rev up it just ran idle. Thats prob why when my friend took it out after putting in the cab kits he said sometimes it would take off but most time not the left engine not rev up...

What could this be just trying not to have to take it to sea doo pay 300-400 bucks if it could be something simple.....

Thanks

your friend rebuilt the carbs and now you're wondering why its not working?
maybe he , or you, or whoever forgot to hookup the throttle linkage properly to that engine?.. will it rev up manually?

I actually dont know much about boats Im remove the air box so I can get to the carb see if the throttle cable is hooked up or broke could that really be the only thing??? He said he hooked them up but I never know until I see for myself.....I can work on 5 hp briggs motors but never a 2 cycle motor I use to race go carts we ran 5 hp briggs bored out carbs made them like to a 13hp

If its broken what is a ball park price on a throttle cable

It was the cable it had broke from the throttle lever not from the carb and sea doo wants 168.88 for a new one....ouch
