    Need help: Bizarre Bravo III freshwater galvanic corrosion quandry

    I'm an ABYC-certified corrosion technician, and here are my two cents.... You need to get a silver/silver chloride reference cell and throw it overboard and see what you get for readings. Anything other than that is guessing at things. If your anodes are NOT corroding, that would point to...

    Alpha 1 gen 2 bellows service

    There is nothing in print other than "inspect yearly". The rule of thumb is that if they are OEM bellows and not aftermarket, 5 years is the expected life span. When they fail, it will start as a slow leak that will get exponentially worse as the tears grow in size.

    Did you run your jumper wire from the keyswitch to the coil yet?

    See my blurb in May's issue of Trades Only Today - https://tradeonlytoday.com/columns-blogs/knowledge-is-power/ I was quoted as writing, "Jason says he often finds that in the marine service trade, skill and effort are inconsistent, but he believes the industry can do better." What I actually...

    The ABYC standard, which is the esentially same as the CFR, just reworded, and more strict says: 24.15.10 Fuel distribution systems shall be provided with anti-siphon protection by keeping all parts of fuel distribution and return lines above the level of the tank top from the tank to the...

    It rotted out from the inside out. The boat builder (who shall be nameless) put the filter in the worst possible spot. I don't think the technicians knew it was even there. I didn't see it until I took an angle grinder to the boat and personally cut the splashwell out of the boat. What's...

    I would be careful. If your fuel system is designed in a specific way, some form of antisiphon protection is federally required, be it a valve or a solenoid. I recently completed an investigation on an insurance claim where the boat, outboard powered, started and ran fine on a Monday. On...

    https://forums.iboats.com/threads/how-to-testing-your-boats-fuel-system.278553/ I wrote that back in 2008. That will tell you how to test it. The only caveat is that it was really written for older inboard carbureted engines. On all modern-day EFI/DFI/HPDI/GDI engines, you really don't want to...

    2005 4.3 liter Mercruiser ignition trouble

    Get a 12-14 gauge jumper wire with alligator clips and clip one end to the same terminal on the key switch, the other end to the positive terminal on the ignition coil. Just run the wire right across the boat. Bet it starts.

    Were we experiencing vapor lock?

    Thanks! I miss New England. Florida has been good to me, but I don't necessarily love it here. I wish I could live in the middle of the woods in New Hampshire, but that wouldn't do much for my career. I'm happy to hear that you are doing well!

    Alpha one gen one trim won't go all the way down

    I hear you, but some locales don't care about water pollution, while others take it very seriously, with serious fines. As an outdoorsman, I would hate to see an oil slick behind your boat on a pristine lake, especially knowing that you know about it. But to each their own....

    Alpha one gen one trim won't go all the way down

    If you had to top off the power trim fluid, then the system leaks somewhere that needs repair.

    Keep blowing my starter solenoid up.

    It's because you are confusing Ohm's law with Watts law. Do ohms law and ohms law only, see what you get. Remember, your light bulb is a linear resistor, so Watts' law doesn't apply the way you think it does.

    I think you mean R = Infinity...... R = 0.0 is a dead short :)

    Were we experiencing vapor lock?

    Lol, busy. I've been doing insurance claims work as an expert for the last 5 years. Between Hurricanes Ian, Helene, and Milton, plus everything else in between, I haven't had time for anything. How have you been?

    Were we experiencing vapor lock?

    It's possible the injectors are leaking down and the engine is flooding.

    Keep blowing my starter solenoid up.

    No, it's not, you have 2 separate problems. The contacts on the solenoid are open when the engine is running, not closed, and 16.8 V is not going to jump those contacts and burn them. First, you are having an issue with your slave solenoid, not the starter solenoid; they are 2 different...

    Keep blowing my starter solenoid up.

    It's true that V = I X R If you are trying to solve for voltage. If you are trying to solve for current, it is I = V / R If you are trying to solve for resistance, it's R=V / I So, let's do a couple of equations. Let's say we have a light bulb that is 1 ohm of resistance, and we are using 12...

    Trim Problem

    Because the switch has excessive carbon build up, or possibly corrosion on the internal contacts, which causes a voltage drop. Replace the switch.
