Well just last week took my boat (83 conroy) out that I had recently bought a few weeks prior and the first time we took it out it ran fine then the secong time we took it out after about 45 min of just cruising around it started to lose rpm's and cutting out itwould be at about 4100rpm then look down when it stared acting up was at around 3500rpm so I killed it and we took a little swim started back up ran fine for another 30 or so minutes so I took it home and replaced plugs and wires took it back out and problemn still there so I was heading back to boat ramp and just out of the blue it dies and wouldnt start.So far I have replaced the points and condenser with the pertronix electronic ignition conversion,cap,rotor,plugs&wires checked if I was getting spark to plugs and I was also checked fuel to carb and when I would push the throttle down I see fuel. Motor acts like it wants to start but never does im kinda of at a stand still here im out of ideas.Any advice is appreciated as im new to boats also the serial # of motor is 6348136 if that helps any. Thanks in advance
