Is all that is needed plates?Depending on the hull, you should be able to get away with modifying the stock plates I'm not sure what is necessary. The krash pump will be fine but you'll want to swap out the impeller for a lower pitch. Something like a 6/12-7/14. They are 5mm setback.
Thanks!! Approximately how much did it cost for all the above? Also, any idea if I need to relocate the same for a reaper?You will need your bed plates re drilled or replaced and drilled to accept the the Yamaha motor mounts. You will also need Yamaha style motor mounts and hardware. You will have to mount your e box to the rear firewall also, I used a box mount from a Wetjet Kraze to do mine. A b pipe will hook right up to the existing water box . I used a Yamaha pump and mid shaft in my ski so I’m not sure what to do about the Krash mid shaft, maybe some other members can chime in on that.
