    procedure to manually flush non-running 4.3 engine?

    Bummer Not to impugn your method but a quick run on freshwater muffs isn't a bad choice for a discerning sterndrive operator prior to launch With as many people pro and con on this forum considering salt water use I'd say you're either 100% fine or it's time to replace the entire...

    2010 350 Mag MPI bravo 3 gaurdian mode issue. 5% power

    I have zero experience with techmate. I have diacom and g3 at my disposal both with current updates so I can cover many ecm/pcm controlled units I agree that 5% guardian is critical, often times if the engine runs seemingly normal under said circumstances the issue is corrosion. Would be...

    Tow rope to Talon bracket?

    Thank you Your OP seemed as though you may be on the verge of catastrophe. Human life is a treasure many take for granted, especially when considering another they've created. This situation not only confuses me but bothers me at times IMO there is never a good reason to visit your local fire...

    AC Mr43T

    Which generation of 454? 454 is a complete different engine from an sbc btw. A 7.4 is light years ahead of forgiveness towards an operator/owner as an sbc

    New 5.7 issues with old(new) starter

    If the removed/missing paint around the hole is not from you installing/removing the starter I'd be curious of the rebuild Iirc, this is the second machine/rebuild shop you've experienced with this motor? And yes, I'd agree with a helicoil/thread repair based on the photos

    Strange engine sound need help

    Haven't scrutinized all the posts in this thread but the broad strokes lead me to think OP needs to replace the sea water impeller, the serpentine belt idler pulley assy, and the serpentine belt That, along with a cleanup of the belt dust/patina on the components will help further pinpoint the...

    What is this? PLEASE

    First WAG I have is nothing related to boats, at least in a pragmatic sense Post a picture of the area/bolt circle in question. It'll help

    Accurate Horsepower Figures

    Correct prop selection requires patience and time. Plus a few props if you're serious First prop I'd try on your setup is a 19 pitch three blade aluminum. Fairly ubiquitous prop used considering your boat/engine and running gear Adjust accordingly for desired performance As far as horsepower...

    Volvo Penta 5.0FIPNCSCE SLOW mode

    The tachometer has a fairly direct connection to the ecm through the coil primary wiring The temprature gauge most likely has no wiring/component association with the ecm

    Overheating

    The balls need to be seated in the barbs at rest Shouldn't take much effort to move them off the seats but it's important that they seat with little/no gap

    Overheating

    They are not The check balls are allowing too much water past at lower rpm. There's not enough supply to the circ pump due to water exiting the exhaust before the circuit pump hose at the t stat housing Remove the balls, turn them around and re tension the springs. Pretty sure it'll aid in...

    Overheating

    Possible failing engine circulating pump? Are the hoses attached/routed correctly to/from the t stat housing? Would like to guess blockage somewhere but with manifolds/elbows being cool it seems like not enough water supply/exit from the block. Pretty sure your 2003 setup does not have check...

    AC Mr43T

    Yes wrong plugs for voretc heads. You need AC MR43LTS Guessing the MR43T plugs were getting blown out due to the electrode not being fully placed within the combustion chamber. The threaded portion of the plug is too short to reach properly. Ignition was occurring within the plug hole rather...

    1980 3.0L strange overheat issue

    10 minutes max at top temperature in the ultrasonic cleaner. Dish soap that saves baby duckies is the best emulsifier. Then go through every passage in the carb, nice and clean. Buy a decent brand rebuild kit, preferably oem Get the valves adjusted proper first, then focus on fuel delivery

    Tow rope to Talon bracket?

    Pretty sure talon states somewhere in the paperwork/online their product is not mean for tow sports. That releases the liability on their end If you love your children, don't use this setup to tow. Install a proper setup and have fun or prepare to witness one or more of your kids visiting the er
