I have an 83 17' Sea Nymph with a 50HP Mariner on it. The rack and pinion steering is toasted on it and parts no longer available so I need to replace it. It was recommended I go to a rotary helm unit such as the Teleflex NFB 147 series . The rack had a 4 to 1 turn ratio, the 147 4.2 - 1 . Now I'm wondering if that unit is overkill for my 50 hp and a NFB SafeT 11 is adequate? It has a 3 -1 ratio ratio.
Can anyone offer some advice?
Thanks
