I'm a newbe looking for some engine help. My knowledge of Yamaha engines is very limited so any help in the right direction is appreciated. All the dealers in my area say its $1500 - $2000 and 5 weeks wait to fix the Waveraider yet none of the dealers have actually looked at it.
I loaned my Waveraider to family for the day and all I can confirm is they sunk it up to the handle bars. I'm also willing to bet they tried to start it while it was sunk.
I retrieved the Waverader within an hour of it sinking and got it up on the dock. I removed the spark plugs and cranked the engine to clear the water. (The cylinders were filled.) I fogged the engine with engine store and used starter fluid to get it running. There was NO water in the Oil or Gas Tanks. I ran it for several minutes and it ran normaly.
However as soon as I hooked the fresh water clean out up, the engine ran rough. After a minute or two, small drops/mist came out the air intake of 2 carbs. I checked the plugs and found the forward 2 spark plugs were wet. The rear plug was dry and so was that carb.
I cleaned everything up and repeated the experiment with same result. The engine ran fine until I hooked up the water and then the forward 2 plugs got wet and tiny drops of water spit from the same 2 carbs.
I removed the head and the head gasket looks fine. If I move the pistons with my fist the front 2 pistons act the same on the down stroke but the rear (working) piston has a small amount of back pressure with a small burp of air on the down stroke. The 2 cylinders with wet plugs do not exhibit this same burp.
I'm not familure enough with the engine workings to guess at what it might be. Some friends say the engine has spring valves and some say no it doesn't With the water coming back out the carb and with the plugs getting wet its obvious water is getting into 2 cylinders but Im not sure how/where.
So far I've only removed the exhaust system and the head so I'm guessing the next step would be either the exhaust manafold or the carbs + intake manafold. but Im not sure. Any Ideas what to look at next?
Also its been about a week since it sunk. I ran the engine with no water for 3 minutes with all 3 cylinders firing. I figured this would let oil get where it was needed and help evaporate any residual water. Then I removed the head and sprayed engine store down the cylinders but no where else. Im not sure if I could have water in other parts of the engine that might cause me problems later Should I be checking/doing anything else to protect the engine while Im working on it?
Whoops I should mention its an Original 1995 WaveRaider 1100.
Thanks
Jim
