just wondering what kind of speed are you getting out of your 174. i have a 1990 174zw with a mariner 115 and a mercury 19 p alum prop and a 6 inch manual jackplate. It runs 39-40 on gps and wot is about 5000 and i can up to 5250. Just wondering if this is setup within reason and i know its a 174 just looking to maximize performance on the old girl.
any ideas would be great
