    NEED HELP QUICK PLS: Replacement Engine choices for 350 MPI

    Just so this doesn't get lost, op should seriously inspect this boat to make sure it's structurally sound before spending money on it. Neglected, then neglected again uncovered for years--op needs to thoroughly check his stringers and transom

    Engine starts to sputter/breakup/lose power after warm 3.0 ‘98

    Plugged anti siphon valve is always a suspect, try removing your gas cap. I'd check fuel pressure next. Might also want to try putting a timing light on your coil wire to make sure you're not missing.

    Strange noise Mercrusier

    Gimbal bearing and/or ujoints. Time to pull the drive (should be yearly maintenance, I'm assuming you didn't pull it at the end of the season...)

    New to me 2015 350 mag, any more maintenance items?

    Fuel filter, grease anything that needs greasing, check the manual for maintenance list, and do all that.

    1994 4.3 Mercruiser fuel pump priming issue

    Glad it's running. What exactly do you mean by "prime"? If the pump is running when the ignition is on and the motor isn't running, that's not correct and is a safety issue.

    Mercruiser Alpha 1 Gen 1 Project

    The moogs will work, as will a bunch of other brands. I just did these a few weeks ago, the moogs were the cheapest at $12

    1994 4.3 Mercruiser fuel pump priming issue

    Yeah, that's the main switched power from the ignition. It should also go to your choke (if electric) and the positive side of your coil. If you're not getting power to the op switch when the ignition switched on, the pump will only run during cranking.

    How to tell what carb I need?!?

    That carb looks like it's open. So that msd isn't hooked to anything? I don't think that's marine rated. Where does the negative wire off the coil go? One should be your tach, one may be to your shift interrupt switch, and one should be to whatever is controlling your ignition. If it goes...

    1994 4.3 Mercruiser fuel pump priming issue

    Sounds like it might have been miswired. Are you getting 12v to the switch with the ignition on? If the pump is getting 12v while cranking (and it runs), and you're getting 12v switched power to the op switch, then either the switch is faulty or you have the wires on the wrong terminals.

    Two year old fuel

    Not sure what MMO would do in this case (nothing to restore bad gas), same with seafoam. One thing I would for sure do is get a sample from the bottom of your tank and make sure you don't have water separated out (check/change your filters as well). If all checked out, and it smelled OK, I'd...

    5.7 with Bravo iii not returning to idle rpm

    What kind of fuel system does it have?

    NEED HELP QUICK PLS: Replacement Engine choices for 350 MPI

    You can get a reman 5.7 for about $3k, and a 6.2L for $4500. As the others alluded to, nothing special about your setup--it's a standard GM block. If I wasn't going to do anything to it, I'd sooner get a used truck engine than a (much more) expensive used boat engine (in fact, I did that).

    1994 4.3 Mercruiser fuel pump priming issue

    So it catches, then dies? But if you prime it before, then it runs (that would sound like the pressure switch)? Did you confirm that the pump does NOT get 12v once it catches? Curious as to whether you have factory wiring, wondering if someone replaced your mechanical fuel pump with electric at...

    4.3 Mercruiser cold start issues

    Well, hell, now I don't know. Didn't jump the switch today, 2 pumps of the throttle and it started first crank, no stumbling or anything once started. Had been sitting since my last post. So presumably the bowl was full.

    How to tell what carb I need?!?

    Suggest that you do what Chris suggested to determine the cause of your low WOT, especially compression test, plugs, other ignition stuff depending on your setup. Also verify that your tach reading is correct. 3500 RPM WOT means something is seriously wrong with your setup, and you have...

    Replacement for perfect seal on drain plugs

    Not a ton of trouble, they're brass, but the engine drains are petcock types and just unscrew by hand. More difficult than need be with the limited access. And one of the drains is somewhere in the bilge atm... I generally try to stay away from Teflon tape anywhere around an engine, but didn't...

    What am I missing here?

    Hey, it's that british guy again! Thanks, informative as usual. The difference between that prop and the others I have must be just due to the prop design itself...
