    5.7 omc stalling while shifting

    It is true that if you prop for heavy load and then run lightly loaded you can come close to or even exceed the redline. Given that your WOT rpm is too low right now it’s not that likely though. Mine is propped to hit 5,000 with just me aboard so if I’m loaded it’s still at the spec of...

    5.7 omc stalling while shifting

    That’s a huge boat for a lil 5.7. Should a had a 454! The valve is where the fuel line from the pump connects to the tank

    One manifold hot (5.0)

    I actually tried going from a 160 to a 140. Found condensation in the manifolds so went back to the 160. When I had the heads off 5 years ago found no evidence of salt build up in cooling passages

    Boat swamped, let's see if we can get it running...

    Let me take this moment to mourn the loss of the supremely reliable mechanical fuel pump on late model Vortec engines….I replaced one…after 30 years….for $80….I can get either the OE Carter or Sierra for either price. In fact if I repower with a V8 I am thinking of going with a Pre...

    5.7 omc stalling while shifting

    That’s hard to say really. You might need a 15x13 for that boat. What’s the length & weight? Looks big in the pic! My 20’ Four Winns weighs about 4200 lbs when I had it weighed a lot more than I thought. It didn’t perform well with the 14.5x19, wrong for the V6, better with the 15x17, but the...

    5.7 omc stalling while shifting

    a couple of points... 1) if you have an advance timing light for setting base timing at idle speed (the advance timing light can be used to check base timing as well as total timing advance) make sure that the dial is set to zero, or else it will throw off you timing setting 2) check your idle...

    5.7 omc stalling while shifting

    That’s basically it, you will need a crowfoot wrench to reach the bolt for the clamp that holds down the distributor so you can loosen it to turn the distributor

    5.7 omc stalling while shifting

    Does Bayliner have a chart that lists what props were standard with various engine options? I know Four Winns did, that's how I knew the 14.5x19 was wrong for the V6 but OK for the V8s. Here's the meter I use, and I have an old Sears Craftsman advance timing light.... Here's a pic close up of...

    5.7 omc stalling while shifting

    Some of my light reading, dating back to 1972. The internet is fine for certain things but for a broad base of knowledge and understanding, it is not. All you get are bits and pieces, not real understanding. And you'll never be a good mechanic without understanding. So now start surfing ebay for...

    5.7 omc stalling while shifting

    If you get a manual & read it through this will all make sense. This is what’s bad about the internet no one reads manuals anymore so people don’t know basics like how ignition systems & carbs work. If you don’t know how they work it’s hard to fix them right…

    5.7 omc stalling while shifting

    well I don't know if you can go lower in pitch than that so you need to look for other causes for the low rpm....because that's way too low and is causing a lot of engine strain every time you pull the boat up on plane, like trying to start up in a manual trans car in 3rd gear. as in... make...
