    Hole shot, Mercruiser 4.3L

    Spotter is already in the bow. I can tell you for sure that more weight in the boat doesn't help, regardless of where it is.

    Hole shot, Mercruiser 4.3L

    That ain't it. I'm even leaving the cooler at the beach. Short double high wrap deep water start takes a lot of oomph. I can do it, but would like to not have a wall of spray in my face for 20 seconds. So wanting the ideal prop for that; I'm OK sacrificing top end, and don't want to be cruising...

    Hole shot, Mercruiser 4.3L

    I think I *finally* have my engine dialed in decently enough to move on to the prop... I have a Vortec 4.3L with an Edelbrock 1409 4bbl carb, supposedly should be around 220hp, but it doesn't seem that powerful. My jetting might not be perfect, and my intake might be hurting me a bit...

    Mercruiser 470 Starter

    Hmm, if you didn't know that then I'll need to phone a friend... @Eric 3.7LX Alpha 1 ?

    What are the 2 sensor on the thermostat housing?

    Poor ground should read low (higher resistance), though who knows, it's a known issue and poor grounds do funny things

    4,3Gi different fuel pressure?

    I'm out!

    4,3Gi different fuel pressure?

    Welcome! I don't know what any of those numbers are... Maybe post a serial number or at least give us an idea of the year and what fuel system.

    Mercruiser 470 Starter

    Yes, or your rebuild shop. 470 uses a standard chevy starter.

    What are the 2 sensor on the thermostat housing?

    Well, that's off. What does the gauge read on a cold engine? What is the resistance of the sender when cold/warm? I couldn't find a resistance value chart for the sender, but other option is to put the tan wire on another gauge after disconnecting the sender from that gauge (fuel, oil, trim)...

    What are the 2 sensor on the thermostat housing?

    More likely you got rid of all that corrosion so there's less resistance through the circuit now. Are you sure it's reading high, or just higher than before?

    What are the 2 sensor on the thermostat housing?

    You should if you're measuring from the gauge side and it's disconnected at the sender. The sender is the resistance

    Mercruiser 470 Starter

    Replace it with a PMGR starter. You can find one for <$100.

    What are the 2 sensor on the thermostat housing?

    1. Yes, if it's disconnected at the sender 2. That suggests you're getting power to the gauge, but either the sender is bad or you have a bad connection/break in the tan wire.

    What are the 2 sensor on the thermostat housing?

    The buzzer has 12v switched power to it. Grounding the wire (or closing the switch on the sensor) completes the circuit. I assume you did theses tests with the ignition on... For the gauge, make sure you're getting 12v to the gauge (purple), and then trace 12v along the sender wire to the sender.

    2002 Mastercraft 5.7 harmonic balancer moving in and out

    I feel like at 3500 rpm under load this wouldn't be a long term solution

    2002 Mastercraft 5.7 harmonic balancer moving in and out

    Can someone explain to me how the hell this would run without your camshaft turning? Certainly can't run for very long...

    4.3 TKS "Run On" fixed but Slight Loss in Performance

    Came here to say that. Iridium plugs in these engines would only be for maintenance/longevity. Nothing in my boat lasts long before being changed for one reason or another, or "while I'm in there". So copper is fine for me.

    4.3 TKS "Run On" fixed but Slight Loss in Performance

    If running a hotter stat and plugs gave you the equivalent of 50 hp, I'd be the first one in line at the parts counter. Switch plugs back first, see if it changes, switch T-stat next, see if it changes...

    Visible exhaust after starting

    Open a bit from the start. Or if it's starting fine, leave it.
