Ive got some problems with my 2000 Four Winns 170 Horizen.<br /><br />I have a 4.3 Vortec 4.3 Volvo SX 190hp.<br /><br />I have removed, rebuilt and installed car engines, and my hardest by far was an 86 Fiero GT v-6, however I have never done a boat before.<br /><br />What manual(s) do I need? Which are the best? <br />Do I need special tools?<br />Anything else I need to know whould be helpful.<br /><br />I can't afford to have someone do this, and is why I am doing it myself. <br /><br />Also. Hoe can I get more performance out fo this motor? I heard I need manifolds that will flow before I do anything to the motor. Will it be worth it trying to make it go faster on a budget? Or should i just rebuild it to stock.
