Hoping someone can help i was out on the water and my ski had started to leak due to the seals wearing out so replaced those however now the ski runs a lot slower!

The water was about 4-5 inchs deep in the ski and bottom half of the engine was submerged....

Has anyone got any advice on what i should be cleaning or checking that couold cause the ski to run so slow?

The ski only gets to 30mph now and was doing 55 mph b4!!!

The ski is a Polaris Virage TX 1200
