    No Spark on 1988 4.3 ltr. engine

    No, don't change the ignition coil. A bad ignition coil isn't why he's getting 10.4v at the ignition coil

    New boat with merc 5.7

    That's a bit different though. I said initially; if it isn't starting and you're getting timing light flashes, I'll move to fuel. I wonder what a poor man's gap tester would be--old plug that you really widen the gap on? On my outboards/small engines I usually can't be bothered to find my gap...

    New boat with merc 5.7

    I'm partial to a timing light initially. Doesn't tell you the quality of the spark, but if you're getting a steady flash you're likely dealing with fuel. Esp in an electronic ignition.

    Help prop an old boat?

    Also, getting the trim sorted first is important. Your wot rpms will be low if you're plowing

    New boat with merc 5.7

    A couple of teaspoons. Don't waste your time on additives. If you have water in your tank, it needs to be physically removed. Do you have a fuel water separator?

    No Spark on 1988 4.3 ltr. engine

    no, and no real reason to. the troubleshooting basically tests each component. each step that you reach ensures that all the prior components work. look up how to do a voltage drop test to determine where your wiring issues are. 10.4v at the coil sucks.

    Fuel delivery

    Have you tried measuring the voltage across the plug pins?

    Are plastic props junk?

    I've had mixed luck with those. better bet is timing light or multimeter or the optical tachs.

    Another prop slipping thread

    if you can see the driveshaft behind the engine, it won't spin if the coupler is bad. Have you greased the coupler ever?

    2002 Chaparral 286 SSI

    I mean, a carb *definitely* isn't as easy to start as FI. Mine is known for draining the fuel bowl after a while, so to not have my boat act like it looks I need to run the fuel pump manually. Most carbs have a personality; they need to be pumped a certain number of times, throttle set in a...

    2002 Chaparral 286 SSI

    advice would have been to water test it, running on muffs is worthless. is that a 186?

    Rattle when in gear

    Smell whatever's in your bilge. Gear oil is very easy to distinguish from motor oil. It can also be leaking into your drive shaft bellows (and possibly then back to the bilge). Unless you can definitively find a leak at the reservoir, your drive needs to come off. Sometimes things like to give...

    Rattle when in gear

    Protip: when your boat starts making bad noises and critical fluids are disappearing, the solution is almost never to give it more gas while overloaded and pulling tubes. Hopefully you didn't toast the drive. Pull the drain plug and check for metal

    No Spark on 1988 4.3 ltr. engine

    you should have battery voltage at the coil. this needs to be corrected before proceeding. a first cheater step would be to jumper a wire to the coil pos and see if you get spark then (note that you'll need to disconnect the jumper to shut down the engine if it starts, or put a plug or spark...

    Tune up problem

    if you can't get them out, drill them out and replace with a machine screw/nut

    Oil in bellows questions…

    and you can find the wrench for around $50
