Hi all... I took my boat out for the 1st. time this year, about 3 weeks ago, & it ran great. No problems at all. Then I took it out the following week & it ran fine most of the day, up until I was about to leave, & then it started crapping out & missing real bad, & wanting to die. I barely made it back to the launch ramps. After I got it back home, I did a tune-up on it (plugs, dist.cap, rotor & new air filter). I also drained the gas tanks, (thinking there might have been some water in there), & filled it with fresh fuel. I also found a couple of the rubber vacuum caps, on the carb. were cracked or split, so i replaced them also. I took it out again this past weekend, hoping that I solved the problem, & it ran pretty good for about 15 minutes, then it started doing the same thing again, missing, stumbling, & wanting to die out on me. So I shut it off for about 30 minutes or so, & fired it back up again, & it ran good, but for only a few minutes, then started the same shit again. The motor isn't overheating (temp. is normal, 120-160), oil pressure is fine, & fuel pressure is fine too. It always starts right up & usually idles fine too, except for when this problem started happening (then it doesn't want to idle very well).
From reading other posts in here, I'm thinking the problem may be in my ignition system, particularly my coil, but I'm not sure. That's why I'm posting this. I'm hoping you guys can give me some ideas, or things to check out, or test... My setup is basicly a stock 455 olds, with a Torker intake & a Mallory Electronic dist. & Mallory coil, Q-jet carb., & exhaust logs. With a Jacuzzi jet. If you need anymore info, I'll be happy to post whatever ya want to know. Well, thanks for any help you guys can give me on this, I appreciate it very much... Thanks again, JT2Fast4u...
