The supercharger is connected to the engine thru a clutch. I think it should slip in case the charger is stuck. But maybe not enough to allow the electric starter to turn the engine. Did you try to turn the engine by hand with removed spark plugs? If the supercherger is stuck it should be possible to wiggle the kranckshaft a little ( play on the command gears and clutch of the charger) Please give us the right Waverunner type...

1. NEVER run gas with ethanol in the engine. 2. When you start it put one half can of anti fogging fluid in gas and run it for 10 minutes. 3. When you are going to store it turn the gas supply off while the engine is running and let the engine run out of gas. That way there is no varnish build up in the carb. 4 change the spark plug twice each season.

Mabe you need to add a stroke or take one away.

Hey Kenneth, PLEASE take this engine to a qualified professional... it will be cheaper in the long run!!

It's not possible to be 100% certain with your information but I will follow the following sequence; first take out all the spark plugs and inspect if they are too dry or with metallic residues (this could tell you about a big failure in the cooling system or lubrication and a possible mayor engine failure) , second try to run the engine with the starter, it has to run very easy without any strange metallic noise. apparently you run your waverunner without correct lubrication or water cooling circulation and the engine was over heated.

You can not test any power pack. You have to test all other ignition components first. If all components test good it could be a bad powepack. First thing first, check ground wire, check all grounds. Make sure no carosen, or loose bolts. Your also want to ensure wire to terminal has a good connection.

No guarantees but here's website to check - http://www.yamaha-motor.com/assets/service/manuals/2000/lit-18626-03-71_752.pdf

You might have 2 bleed the system 2 make sure their is no air in the system

How long has it been since you changed your water pump? The pressure relief valve can also cause over heat issues if it is stuck.

the weight of the motor will be obtainable from the Yamaha web site in the specifications section the weight of the boat is any body guess as you didn't give a manufacturer name most marine shops will get close as they are familiar with boat constructions and supply trailers to suit
