Newbie on this forum, hoping for some clues.<br />My brother and I have an 85 or 86 Cobia Sportster with an OMC 3.0 (GM) The boat has run great for the past few months and just up and quit on us. Originally thinking we ran out of gas, we thought some goo was sucked from the bottom of the tank. I removed the last 4 gals of gas from tank, changed all the filters, the H2O Separator, and cleaned the carb. <br /><br />The motor seems fine when there is no load placed on it, Revs and idles decent (not like it had before though). Put into gear and it craps out. It will accelerate, then bog, then accelerate, then bog. I thought it was a fuel related prob. After dealing with everthing in the fuel delivery system (Except pump) And tinkering w/ the timeing. I am at a stand still. I have experience with engines, but none with points. Every engine I've ever owned has had electronic ignition, even my dirt bikes! Could the points be causing this flux in power? Is there a way to test an engine under load with out taking it out? (Boat is in driveway, river is 30 min away). Any help is welcomed. Money is very limited so a shop is out of the question for now. <br /><br />TIA
