Hello, I am new to this site and pwc's but have quite a bit of experience with engines...as I am an R&D technician for Stihl. I have several questions regarding an engine swap I am attempting...hopefully someone can help. BTW, this is a low/no budget project, I have a manual, and I don't have access to any special tools except what can be rented. And the white motor ran when in the donor pwc just before I removed it. Ok, here goes:
1. Is there any reason I cant swap a 1993 SPI white (really its biege) 580 Rotax to a 1991 GT which had a yellow 580 Rotax? Anything I should beware of?
2. I swapped the yellow magneto/coil/ig mod/housing to the white engine because I read it had more power and made the swap easier...is this true? Anything special I have to do?
3. Should I be able to run the engine out of the pwc with the 5 wires coming from the magneto area disconnected? I tried and am not getting any spark. If not, how can I verify the electronics are working prior to mounting the engine?
4. How should I shim the motor when performing a swap...and have lost track of where they were anyway?
5. I found some broken plastic pieces around the impeller...how hard is it to remove the impeller and related components? The manual shows all these special tools...are they required? Are impeller related failures common?
I would greatly appreciate any help you all could give me! Thanks, Dave
