This engine has Walbro carbs, turnfin is is Cmdi, strut us round again Cmdi, rudder is speedmaster. On the jug size just a word of caution if you plan to race it. Both NAMBA and IMPBA limit the displacement to 52 CC on two 26 CC motors, you will find this in the rule books. Insurance will not cover a bigger motor and the insurance policy states one must follow the rules so you will probably have CD's stopping you from entering. Suggest you stay with 26CC jugs.
Good luck with your new build. What hull do you plan build?
