    Lost keys

    Yes, once we confirm your ignition key switch type and small number and/or letter normally found on the front base of the key switch, you'd be able to order a new key already cut that matches your switch either by part number from "Merc" (Mercury Marine) or some online key locksmith stores that...

    Alpha 1 Gen 1 Upper Unit Hex Bolt Connecting Halves Broke Off

    With the head of the bolt removed now, maybe treat it like a stud and use a Stud Extractor tool to help get it to come out… still would need more heat and oil though should you not want to use the welding trick.

    Carter P4389 Doesn't Work when Connected to Carburetor

    Looks like you mostly have/had a 1990 engine year model with some upgrades. :cool:(y) Your newer model carburetor won't be in your parts guide though but as promised in case you need it, here would be your initial parts catalog that should fit a majority of the parts left on the engine...

    Carter P4389 Doesn't Work when Connected to Carburetor

    If you get fuel right up to the carburetor connection fitting, but the fuel isn't passing through the carburetor to fill the bowl then you possibly have either the carburetor fuel filter/strainer at the connection point plugged up or the needle and seat is stuck inside the carburetor and not...

    Ice Maker Identification

    If it’s not making ice due to water flow then maybe it’s something such as a clogged water line, filter, brittled up water line causing leaks or air to the maker. On boat types such as those, should the original owner still have the all the paperwork from new, sometimes mixed in is the build...

    Ice Maker Identification

    Have you had a chance to image search marine ice maker brands for boats? There are a few that appear close to your design except for the upper shelf type handle, other than that, the U-line brand found at places like West Marine seems close but so did one from Isotherm. By change, is there any...

    Oil coming out of carburetor

    Doubtful the following bulletin from Mercury marine would be your exact problem and it isn't for your engine model but I'll share it just to help gain ideas of other possibilities too...

    What fuse or blown component would prevent starting?

    Check for 12v at the red button 50-amp circuit breaker on the engine and also at the orange wire off the back of the alternator stud. Item number 19 and may as well check 27. https://www.mercruiserparts.com/bam/subassembly/31920/959/70...

    Low Fuel Pressure 2005 Mercruiser 4.3L MPI

    How does the engine/boat perform while on the water? Have you tested the fuel pressure while underway too? Need to know what happens when you pull off the small rubber vacuum line at the fuel regulator nipple connection point. It's still possible to have a compromised fuel pulse damper that's...

    Clamp Ring Seals

    What model/number stern drive and year is yours? Volvo Penta “AQ” series. My initial thought is you might need the transom service manual to help locate that torque number such as these for example, https://www.ebay.com/sch/i.html?_nkw=7732703&_trksid=p2332490.m4084.l1313 This mentioned...

    Low Fuel Pressure 2005 Mercruiser 4.3L MPI

    In seeing your photo, this may sound slightly silly but you may also want to try a new Mercruiser fuel filter vs aftermarket Sierra Marine filter mostly because the OEM filter is 25 microns and the Sierra Marine one is 10 microns… Doing a quick search also suggests that microns can be...

    Low Fuel Pressure 2005 Mercruiser 4.3L MPI

    Pull the fuel regulator vacuum line off while the engine is running and see if the psi goes up roughly 5 psi also make sure there’s no fuel in that vacuum line/coming out of the regulator. Plus may as well check for full battery voltage at the fuel pump wiring harness so you know for sure. If...

    Low Fuel Pressure 2005 Mercruiser 4.3L MPI

    What fuel regulator did you change, the one up on top of the engine at the fuel rail or the one down by the fuel pump? Hopefully the one down by the pump. If you fully were/are able to be sure to block off the return line heading to the filter base housing assembly, then the pump should be able...

    Low Voltage to the Ignition Switch

    In reading the quote above, does your boat have a battery switch and 2 batteries?.. (Battery 1, battery 2, All batteries) if so, thinking you may have a bad cable to one of the batteries too…

    Axius Gen 1

    I was thinking your boat came with it uninstalled by someone else and you got it back together with hard work and persistence? Also, there may be a bit more info here for you, https://forums.iboats.com/threads/axius-gen-1-removal.776085/#post-5956908
