Help with 2000 Ultra 150

[theONLYbigHEAD]

Hope it's alright to post about an Ultra 150 here. But I have a 2000 Ultra. The ski runs awesome most of the day (65mph and strong). After a good hour or 2 of riding, it seems to want to fall on its face. Losing power, amd when pulling throttle wide open the ski only wants to do 10-15mph. Any idea on what would cause this? Thanks in advance and again, I hope it's ok to post this here.

Is your high temp warning light on the dash flashing?

My ultra used to do something similar if it's cooling line filter blocked. It also did it once in the middle of the summer in shallow/hot water after a while.

Huh, I'll have to check and make sure it's cooling down ok. Thanks for the reply!

I've never had a high temp light come on though, so I'll check all my cooling lines.

What do the plugs look like?

They are good now. That was my initial thought, that maybe I fouled a plug, so I bought new ones late last season when this issue started occurring. Hoping to get the issue resolved before this season is in full gear.
