Thanks for the info. Called Cobalt, and it is warranty work. Called the dealer and sent pic. Will replace the pad. I am not going back with the letters as they are going to be a problem later down the road. Don't need the letters.

Do I contact Cobalt directly or go through the local dealer? Thanks

My 2021, which is still under warranty, the SURF letters are coming off. I was able to save the F but lost the S in the lake yesterday. Assuming these are warranty items?

Had a great day on the water yesterday. Have the port side wake dialed in based on the feedback here. 11.6 speed, ballast port side full, center full, starboard 1/2, trim 3. I'm struggling to get the starboard to clean up with the same settings flipped. Any suggestions? Maybe my R8 is gonna be a ...

I like it; we just haven't perfected the wave yet. We will get there.




Finally got to surf this weekend after the correct impellers were put in the pumps.



Just some follow-up here. Had all 3 pump impellers replaced. Took the boat out to test it and use it this weekend. No dice. None of the ...

Great info will try these settings too.



Interested in this thread as I am trying to get my wave perfected in my 2021 R8 Surf. What is TPM stand for? Trim? Thanks, in advance.



We have found that the lower the TPM the smaller the wave and the higher the TPM the higher the wave. To lengthen ...

Back to the dealer. We haven't been able to surf all summer. Super frustrating! Will see what this week holds ...

There are 3 pumps in my R8S. I had them all three replaced.

I thought so too. Thought it was odd. Called cobalt and they confirmed the ballast impeller is not covered and also recommended having them replaced yearly. Don’t shoot the messenger. 🤣🤣. Just wondering if there is anything else that needs semi annual/annual maint?
