I have a bayliner Jazz Jetboat with a 120 hp. Year is 1995. This is a great little boat except it is very slow out of the hole. I am not sure if I need to replace the impeller and if so, should I put in a stainless steel one? Another option I have read about is the "smart tabs" that will help with getting on plane quicker and help stop the "porpoising" that it does in rougher water. Once I am on plane it runs great. I usually have to make my two kids sit towards the front to get on plane. I just need some guidance on what is the best direction to go in or if this can be improved. Thanks!
