Here's an odd one. 88 470, starts and runs great on muffs, starts and runs great on the water for approximately 30-45 minutes then randomly will start to sputter, slowly lose RPMS, then die. If i let it sit for 20-30 mins it will start back up and run for a little bit again, then the same symptoms. Get it home, put it on muffs and it runs great. One thing I did notice the second time it stranded me on the water is when I went to trim up the boat lost power, you could feel it cut out, pretty consistently (but only after about 30 mins on the water) and then those symptoms above started happening. I am running the Pertronix Ignition System and Flame Thrower Coil, I also am running the alternator conversion from Breeze Works (yes it is putting out abouet 13-14 volts). Ive replaced the fuel filter, water separator, blown out the vent lines. Complete fresh tune up last year (plugs, wire, cap rotor) I cannot find the anti siphon valve (any help finding that would be appreciated). I am pretty stumped on what this can be, like I said the boat runs fantastic for about 30-40 mins then sputters, loses power, and dies. If you need any more information to help "troubleshoot" this let me know. Thanks!!
