Hello I got this boat for free. Its a 1991 Maxum 2100SC. Someone installed a 4.3 motor from an S10 Pick up truck. He added the marine cooling system parts. My problem is they tried to use an inline fuel pump with no way to regulate and control the fuel supply. From reading about the S10's they used a TBI carb, A submersible pump controlled by a throttle sensor. And this motor just does not run right with this current set up.. How can I modify this so that it runs correctly? What do I need to do? The engine is in good condition. Good compression. Thanks.
