97 seadoo challenger, slow out of the hole, low top speed

[Kalkake]

Just picked up a 97' seadoo challenger with a single 110hp rotax. Boat is in great condition, fires right up. Took it out 2 days ago to the lake and have an issue with it coming out of the hole. I can punch the throttle and it revs right up to 6500-6800 rpm and the boat starts to move foward, but just doesn't "grab" in the water. Likes its slipping. But after 3-6 seconds it's grabs and gets up on plane. Once up I can get it up to about 38mph with 2 people on smooth water. Motor sounds great, rpms hold at the 6800 rpm mark but can't get over 38mph. I have attached a few photos of the impeller from the intake side. There does seem to be a slight Ridge or the wear ring, but can't tell if it's normal or worn.

I have read quite a few posts on here and other forums about the wear rings, damaged impellers sucking air through the bottom plate or the carbon ring.

Just looking for a few "pros" to chime in and give advice. It looks fairly straight forward to rebuild the pump, but don't want to be chasing my tail if it's something simple.

Thanks in advance!

I guess the other question is, does the impeller look OK, or should I have it repaired? I have an extra jet drive, but not sure of its condition. I will have to get pix tonight.

The blades and wear ring don't look good, better pull the pump off for double check, you might need a new prop and a new wear ring. My Speedster 155 would get on plane at 3500 rpm.

This what your pump should look like, that's a new OEM wear ring and impeller in a '97 Challenger pump.
