Hi - hopefully someone knows the answer - i have just bought a 16'1" ski boat with two yamaha 60s. The boat veers strongly to the right - I understand that a boat would have a tendency to pull or veer to one direction due to the rotation of the props but the amount of pull even when idling is unacceptable. Is this a function of the pitch of the props, or is purely a trim tab adjustment. Any advice? Also - the boat came with a strange gauge - has stabilizer written on it - what is this for and how does it work. TKS
