I will try that next. Thank you.

So we replaced the TPS and took it out for a drive. It did not stall as it usually did when coming off of plane or driving along at between 2000-3000 rpms. I did have something else happen that was...

I am wondering if anyone can tell me if the throttle position sensor on this motor would cause the motor to just die? I have tested the TPS with a multi-meter and have found that there is a spot when...

I'll be anxiously awaiting others replies to this to see what they run out what they do run.

I have mine set at around 4"below pad. I've got a 200 Yamaha on mine with a 25m prop. I have thought about trying mine higher. I currently don't get a rooster tail at all with mine and hole shoot is...

Well I thought that I would give everyone an update on my motor. I put the new O2 sensor in and took it out a week ago and it did not help me to get back the 300 plus rpm that I lost over the summer....

Well I bit the bullet and bought a new O2 sensor and hopefully it will arrive this week and maybe if the weather warms up a little I can get out and try it out.

Well I replaced the leaking lift pump and the surging seems to be gone but I am still not able to turn the engine as fast as I used to be able to. I am only able to get to 5600 rpm. I am hoping that...

I cleaned the O2 sensor and had the mechanic test it when it was in the shop. If the pulser coil is going bad will it drop cylinders or cause a weaker spark???

Well I had some down time so I decided to take a look at my lift pumps and so I backed them off and squeezed the primer ball and low and behold the middle pump began to leak! I just installed these...

Well I found a bad coil and replaced it. The motor seemed to run better and would run up to 5600 rpms. I fished a tournament on Sunday and a new problem has come up. Now the boat will surge about 300...

My charging voltage is always above 12.5. I took the boat back to the shop that had looked at it previously and they said they found no problems now after I changed the bad coil. They said that it...

Compression all between 120 and 125.

Took the boat out on Saturday to try it out. It was really windy but I did a couple of full throttle runs. I feel that the boat does run better with the new coil and my rpms at wot throttle do not...

Update 3... Well the new coil arrived and of course it was the wrong one. Distributor screwed up but they are sending me the correct one. Should have it today. Fingers crossed!!!

2nd update... Well the Yamaha dealer turned out to be a waste of time so I am back to testing on my own. I purchased a spark gap tester and proceeded to start testing each individual cylinder. I set...

Update on progress. I took the boat to a local Yamaha dealer and they are telling me that I have weak spark/intermittent spark on 3 cylinders under load. Anyone have any experience with a weak spark...

I have an 03 vx200 that loses rpms while at WOT. I have replaced the vst filter, lp pumps, cleaned the o2 sensor and tube, checked the tps. I am at a loss on this. I used to be able to turn 5900 rpms...

The idle seems to clear up once I have run the motor wide open for a while. I have replaced all the gaskets and seals prior to this season an cleaned the o2 sensor and dog bone which were packed full...

No one with any ideas?

I am still having issues with my 03 225 ox66 it is the vx model. I have excessive smoke when I first start the motor and this happens every time I start the engine. There is also oil leaking from the...

So it should idle pretty smoothly than? Rich Z what is the recommended idle while the boat is in the water in neutral and while in gear? I always thought that from what I read they shutdown cylinders...

Luckily for me I did have the template far enough forward and I did miss the bin underneath. It was definitely nerve racking cutting through the layers and foam but I am so glad that it is done and...

I took the boat out on the river Saturday afternoon and the motor will fire right up but it definitely has a big cloud of smoke when you first start it up. I have taken Rich Z advise and cleared all...
