I have a model sb-200 snowblower.It has the 5.5 fan motor.I have a s-185 high flow machine.The blower works ok at best..I would like to get the 9.6 fan motor and then run the blower in high flow mode .Question is what do I have to do to make this work.I looked on the parts fische and it seems like you need a different 7 pin harness for high flow and I also herd the 9.6 motor uses the case drain line.I would assume this is possible any info would be great.Thanks
