Hi Garry how do the bigger sikks compare with a zen as regards rpm? i know they have lots of torque for big props etc but would it be a good choice for say a hydro with a small prop or would the smaller one or a zen be better for that type of boat.Reason i ask is because i can get the 27 sikk for a decent price with mounts but wasnt sure it was the right motor for my new shovelnose hydro (rocket) spinning a 6717/3 prop any help appreciated,sorry to hyjack the thread but it may give you some extra info
