    1996 SeaRay 215 Express Cruiser electrical issue

    You're all over the place here. First post says alt output is 15v engine running, now it's 12v? Also, you said the slave solenoid was good, but then it tested bad? It's fine you're testing and replacing components of the starting and ignition system but those systems have little/nothing to do...

    Mercruiser Trim Issue (not the usual issues)

    OPs first post mentions the pump working both up and down. Can guess by this that most likely both solenoids and the pump are sound. Based on info provided I'd suspect that one or both the rams have an internal issue or more likely one or more of the valves in the pump is sticking

    Replacing Alpha Gen 2 upper and lower housings

    Most repair shops won't even swap internals due to the labor cost outwieghing the cost of replacement alpha style drives/housing assemblies. This along with a manufacturers warranty and repair time makes re shimming an alpha style drive a thing of the past Bravo on the other hand is still quite...

    Alpha 1 Gen 1 - Teardown - Need Advice

    Are you referring to the welch plug on the side of the driveshaft housing for the shift slide cavity? If so, clean out the cavity and install a new one, they are available from merc Water pump housing fastener has most likely been replaced with a ferrous nut. OEM is chrome plated brass, could...

    4.3 mercruiser overrev alarm

    Never said it didn't Far out, but we're talking sterndrives here No doubt the engine is smartcraft capable but again, OP hasn't revealed much info on the setup. Many smartcraft enabled engines were installed in boats that did not utilize smart guages. Sea Ray has and still does manufacture...

    4.3 mercruiser overrev alarm

    Yes No. I've never seen, heard of, or read anything about a trim fault based on engine rpm/limit with 555 technology. You sure? OP hasn't posted much info regarding set up/serial number. Unless there has been a massive upgrade it'd be odd for a twin 4.3 merc setup to have DTS given the...

    4.3 mercruiser overrev alarm

    Agreed Mercruiser trim faults aren't set according to engine rpm and given the vintage only occur with smartcraft.

    Lost gearage?

    Most likely an alpha gen 2. Like bondo says, pics will help ID your drive

    350 mag MPI will not turn up past 3500rpm

    350 mag mpi bravo? alpha? Correct prop is useful, more an art than a science Other science would think a fuel supply issue may be the culprit

    4.3 mercruiser overrev alarm

    Maybe, if it is indeed the switch triggering the alarm. If not, it could be any number of issues causing the alarm. This is why you need a diagnostic tool to verify exactly what is causing the fault. Otherwise you're just guessing, and that gets expensive quickly Seeing as how both motors...

    Exhaust manifold Replacement questions

    Not bad for four years, rinsing with freshwater/solution is key for salt/brackish water use Would be more interested in seeing the water and exhaust passages at the seam between the manifold and riser, also is good to inspect for water intrusion in the manifold exhaust passages

    4.3 mercruiser overrev alarm

    Located on the shift plate assy, as stated it looks like the shift interrupt switch for an alpha setup. The switch allows the ecm to know if the drive/cables are in the "in gear" position. Alarm would be sounding for over rev in neutral. FYI if the engine is struggling to achieve 3500 rpm under...

    4.3 mercruiser overrev alarm

    Being a bravo I'd first suspect in/out gear switch. Similar to an alpha in appearance, but only tells the ecm (efi only) whether or not the shift plate/cables are actuated in gear or out gear (neutral) Only true way to know for sure is connecting a diagnostic tool that can verify...

    3.0 Mercruiser seems to hang or seize when starting

    Pragmatic advice seems to fall on deaf ears around here lately

    Rebuilt Mercruiser 5.0 won't start, ideas please?

    First verify good consistent spark, gonna guess thunderbolt based on given info. Then check fuel quality/supply As far as no audio warning system verify the horn is operable and connected properly

    97 Mercruiser 3.0LX will run/won't run

    Agree with Bondo here. You're putting the cart before the horse. Troubleshooting is a step by step process, you can't skip steps. You'll just end up wasting time and money thus increasing your frustration Yes, the shift interrupt switch can cause the ignition system to cut out, its part of the...

    Motor won’t turn over

    You need to set idle speed and idle air adjustment. A carb rebuild isn't just plug n play

    Motor won’t turn over

    At what rpm was it running? Should have the throttle advanced to about 1200 rpm on a cold motor til the choke starts to open

    1996 SeaRay 215 Express Cruiser electrical issue

    Items mentioned here don't have a direct correlation with the charging system. Great they are all sound but even if any of the above mentioned components/systems had a failure it most likely would not affect the charging system Posted info earlier mentioned 15 volts running at alternator...
