[QUOTE="Big_Kahuna, post: 327645, member: 12487"] im curious... if you have a 15 inch transom on your boat and your motors a short shaft and you have a mini jacker that provides 3 inches of lift how can your cav plate be 1/2 inch above your keel? them numbers tell me your cav plates 3 inches out of the water. 15inch transom with a short shaft motor(15 inch shaft) should make the mini jacker useless and put your lower right where it needs to be. correct? as for only getting 5,000 rpm's how are you coming up with that #? tachometer? if so you need to try a prop with less pitch or re arrange the weight in the boat. but really 16mph is not bad for your set up and a 15hp motor. id guess that if you can get 1000 more rpm's you would be at 20mph or maybe a hair more....[/quote] If the transom was squared up I would say that would be right but it's on an angle.
