Good day I am the proud owner of a 1998 Seadoo Challenger 1800 Twin 110HP Rotax. I replaced both engines recently cause just thought it was time to compression on previous engines had gone down and one constantly was melting rave valve tops. Anyways I took the boat out for the first time since replacing engines and the RH engine full throttle keeps bogging up and down from 7200-5000 RPM's this also has new wear ring, rebuilt pump and impellar, along with 2 new rave valves. What can cause the engine to bog like this??
The LH Engine starts up and idles PERFECT but when I give it full throttle will only rev up to 4000RPM or completely shut off. I just purchased brand new carbs from Mikuni for this engine but is there anything else that can be causing this problem??
