    Engine misfires after rain storm

    Yeah, ha ha actually going through that right now with my Merc. Has spark with the light but weak on a gap tester. Still a good first test I think, and if it's missing you know it. Also guessing that a weak but not absent spark is more common with a stator driven ignition, multiple places to...

    Engine misfires after rain storm

    Any water entering your fuel system? Are you sure this is an electrical misfire?

    Bilge Plug & bilge pump placement

    I mounted my pump to a piece of metal, which lays flat at the bottom of the bilge. It's stable enough that I never fastened it to anything. Easy enough to remove and replace

    Advice on Buying a Jon Boat

    Agree with this. You can probably get on plane with just you, maybe one more with that 15. If out "with the family" just expect to be puttering around. Definitely water test with people on board to make sure it runs ok and can perform like you want/expect.

    Artificial Intelligence

    ok, so real world testing incoming...this is a lot of text, but whatever. My 25 hp merc died suddenly (again). 2 years ago had similar symptoms, turned out to be the stator. Information provided to chatgpt: 1. Weak spark to both cylinders, unable to jump gap on tester 2. DVA voltage on both...

    1997 5.7L thunderbolt ignition. Slow crank

    Didn't compare all the specs, but have dealt with MM a few times for tech advice and buying other parts--these guys know their stuff and have great customer service. If everything was close in terms of price, I wouldn't hesitate going with them.

    Constant drain of 1 of 2 batteries

    Yeah that's why I said "regular", would have to be a relay trigger with the relay near the batteries, which is what it sounds like. A stuck closed relay might do strange things

    1997 5.7L thunderbolt ignition. Slow crank

    Personally think that if you're going used (rolling the dice) you'd be better off with a truck engine. Even abused, the block has an easier life than a marine engine.

    1997 5.7L thunderbolt ignition. Slow crank

    I'll say I wish i didn't install a relay on mine and just wired it like OEM. Many connections have given me trouble, although my boat is...special.

    Constant drain of 1 of 2 batteries

    Can't be a regular battery switch, it would take too much high current wiring

    1997 5.7L thunderbolt ignition. Slow crank

    As mentioned you didn't need to mess with a cam. You need a marine fuel pump. Then yes just switch your stuff over. Wiring will be a straight swap as well. Vortec isn't any harder since you'll be pulling heads and manis anyway.

    Constant drain of 1 of 2 batteries

    So no connection between the batteries? What's a parallel switch? And stbd is the draining battery? Seems like an odd setup.

    1997 5.7L thunderbolt ignition. Slow crank

    Wow, was looking over at michiganmotorz... things have become crazy expensive! 1. I personally wouldn't sweat getting a higher mileage engine. My 4.3 had at least 200k when I pulled it 5 years ago ($180). If the compression is good, you're set for a while at least. This would at least give you...
