    Interchangeability Tigershark 640 93-94

    Long time listener, first time caller!
    We've had a 1994 Daytona for many years and it ran flawlessly until yestaerday. No spark. I can go through the motions and try to troubleshoot and throw parts at it from eBay or there is a 1993 Tigershark 640 for sale locally with a bad cylinder for a couple hundred dollars. The hulls are completely different. However, from pictures the engine seems to be the same. What are my chances somen of the electronics and mechanicals are interchangeable? Anybody with any experience with both skis?
    any insight appreciated. I'll hang up and listen to your answers.

    Cheers!!!

    Welcome caller! From the few things I just looked up on the parts database, the CDI, engine, ignition coil are all the same part numbers so I'd be willing to bet most of it you can use.

    Thank You for your help and time researching. I tried google for parts searches on both without much luck. May I ask which site you were using for future reference?
    I appreciate the help. Now I can make an informed decision on what to do.

    Browns Leisure World is usually the site I use when researching part numbers because they have a feature where you can see what else uses that part.

    they are a good site i use too to compare part number and 93-94 part are interchangeable. piston dont have exact size because 93 are 644cc and 94 are 640 but after year probably they are rebuilt and have identical piston in each machine.

    So what's the chances I can swap a 94 640 engine into a 93 644 without major modifications? That's where I'm at with these two skis.

    Engines don't matter. Absolutely nothing matters. If it even hints that's its brothers cusins aunt's neighbor is a 640 engine part it's interchangeable absolutely nothing matters. Different combinations of pipes and carb set ups will change the performance but other then that there is nothing to worry about as long as it stock skis we're talking about. I can't help with after market stuff. The only differences are the crank shafts between the 1996 and 1997 model years and up. They changed coupler design and for whatever reason they changed the diameter of the crankshaft end that's threaded. The rest of the crank is 100% identical but the threaded portion is much larger. To combat this on the older machines you should take your new engine and old style coupler to your local machine shop and have them bore and tap the coupler to the newer style crankshaft. Other than that, if it came on a ski that had a 640 engine in it stock, it's all the same no matter the year. The 639cc as it was specifically and the 644cc are all the same as well. Pistons interchange but rings do not unless the 639 gets bored out to 644. Same cranks, carbs, exhausts, heads, jugs (the 644 was just bored more stock), pistons, magneto, ignition systems, most of the fuel systems, most of the pump parts within their year gap (93'-96' and 97'-99' as the pumps changed in between), you name it.
