Was out in pretty rough water yesterday and it seemed to have limited power but ran well. Today it's only running on the front 2 cylinders and won't go over 15...... any ideas????? electrical maybe?

I Have a 2006 yamaha vx110 runs good for first 30 mins then stalls and wont go faster than 4mph. put a scanner on it gave me code 23 and 29. any help

Always change the plugs on a VX as the first step with any performance decrease.

If plugs don't solve the problem, do a compression check and report back.

I changed the the plugs, has good compression. I hooked up the water hose to the Ski and instead of pushing the water tru the system just pushes it tru the exhaust.

The cooling water is dumped into the exhaust after running through the jackets around the engine etc.. Are you getting an overheat alarm? Are you getting spark on the 2 plugs in the bad cylinders?

 

[southfisher]

I check the cylinders firing good, did get and over heat alarm and ski goes into safe mode. wont run over 4mph. was wonder if it cud be gaskets in the intake.
