    2005 seadoo gtx supercharge ?????

    I have a 2005 gtx 155, i like to know if i can make it a 185 by just adding a supercharger, do i need to do anything else with the motor when adding this supercharger? or just add it and thats it. as far as i understand the only difference betwen a gtx 155 and a gtx 185 supercharged is the superchacher, is this true or false?

    i have a better solution...sell it and buy a gtx 215, the cost its gonna take to convert the 155 into a 215, your better of buying a 215 and Welcome to the forum

    At the least you would need to replace the PTO housing, because yours does not have the hole where the SC mounts. You will also need to replace the flywheel because yours does not have the second row of teeth to drive the SC. Then you will need to change the pistons becaue the NA engine has higher compression pistons than the SC engines... Ron
