    1993 7.4L Gen V Fuel Pump Issue?

    Serial Number 0F009622 1) Can't get my engine started and decided to look for fuel pressure. I disconnected the fuel line from the pump and turned over the engine. No fuel comes out. Bad right? Can't be the anti-siphon valve preventing the pump from pumping? 2) Someone posted a few years ago...

    Bravo 3 trim cylinder leak

    My recommendation as well. I've done it, it's not that hard. The trick is unscrewing the "caps" at the end of the trim cylinders. If I recall how I did mine, I believe I just ended up using channel locks with a rag between the locks and the caps so as not to ruin the aluminum. Go to YouTube...

    How hot is "too hot" for Mercruiser 454 mag temp?

    Earlier this year I was also struggling w. overheating on my 1998 carb'd 454. Was reaching temps slightly over 200. I changed the impeller and the impeller housing. Now I have a hard time getting it to get to temp. If I were you, that's where I'd start.

    1994 MerCruiser 7.4L / Bravo 3 26' Envision

    One thing I would point out is that the exhaust elbows have caps on them indicating that someone converted this from the "old" style thermostat housing w. overflow check valves to the "new" style housing w/o check valves. Someone more experienced than me can comment on whether or not this was...

    Starting Issue After Unrelated Mech Repairs

    Not jumper cables. These little jumper wires. You can buy them a Harbor Freight, etc. Yeah, it would be tough to get jumper cables on that little terminal.

    Starting Issue After Unrelated Mech Repairs

    Here are my suggestions at this point: Forget about the question of whether or not the two circuits are separate or not; it’s not relevant at this point. You’re trying to get at least one engine started. It *should* be really easy regardless if the systems are interconnected or not Forget...

    Starting Issue After Unrelated Mech Repairs

    Didn't you hear the remote starting solenoid click when you turned the key? If so, then it's not your Neutral Safety Switch. The problem is downstream from there. You're confusing the issue here. On your ignition switch (key), you have 3 modes: OFF/RUN/START. Accessories ONLY run during the...

    Starting Issue After Unrelated Mech Repairs

    Pegging to max is definitely odd. I would just use a multimeter to verify true voltage. Regarding whether or not you have true truly separate electrical systems, this should also be a simple test. If you check resistance from one engine block to another, if it is ~0.5 - 3.0 ohms then they are...

    Starting Issue After Unrelated Mech Repairs

    Do you have a multimeter? You can verify that the neg terminal corresponds to a specific engine by measuring Ohm resistance between the negative terminal and the engine block. I would expect less than 0.5 Ohms of resistance. However, something higher might indicate exactly what you're looking...

    The engine stalled and no start while on the water

    If it does turn over, my suggestion would be to get a can of starting fluid and spray some in carb then try turning the engine over. If it sounds like it wants to start more than it previously did w/o the fluid, then it sounds like you have a gas delivery problem. If there is no improvement, I...

    Fuel pump/carburetor

    As per another thread, Holleys are not very common on Mercruisers and certainly not OEM AFAIK. So I don't think anyone is going to be be able to tell you where it "should" be on a Holley.

    Starting Issue After Unrelated Mech Repairs

    Quick useful diagnostic tip: Take a pair of jumper cables and connect the end of one color to the negative battery terminal. Take the other end of the same color and clamp it to the engine block near or even better on to the body of the starter. Be careful not to touch the either of the "red"...

    Does anyone have pic of distributor on Merc 7.4 Gen V?

    I have a 93 Gen V 7.4 in my Chaparral but I don't think a picture would help. (And I don't have one at the moment). The distributor can be installed any way you want in a 360 degree manner, so long as, like you indicated, the rotor should be at or right before the #1 cylinder when it is at TDC...

    Lower compression in one cylinder boat won’t start… ideas before I tear down 😒

    In my opinion a valve that is stuck open is the best case scenario for low compression. You asked for suggestions before tearing it apart. My suggestion would be to remove the valve cover and look at the valve assembly for the questionable cylinder while you turn over the engine w/o starting it...

    Mercruiser 5.7 2001 - choo-choo sound - what could it be?

    Sounds a lot like my 7.4 when I blew a spark plug out because I didn't tighten them well enough. Hmmm....I blew the spark plug insulator right out of the thread jacket....

    Bravo 3 stuck in reverse

    If it were my boat, I would FIRST detach the lower shift cable from the shift plate and try to manually shift in and out of gears. If you can successfully shift manually (holding the outer sleeve with the left hand while pulling the wire core assembly with the right hand), then this is an...

    Impeller issue on Alpha 1 Gen2?

    The more experienced guys will chime in soon but I had a bad Bravo impeller and steam coming out the transom exhaust was the visible symptom. One quick method to start pinpointing your problem is to disconnect the raw water input hose at the t-stat housing and look for how much water output your...

    Bravo Shift Cable Bellows Ripped in Half....

    OK I forgot why I read Chris' original post 10 times. Chris is saying that the entire nut/gimbal side stays intact. It is the shift plate (engine) side of the cable that will be pulled back through the transom plate aftward towards the transom assembly. A cord will be attached to the "engine"...

    Bravo Shift Cable Bellows Ripped in Half....

    OK guys thanks for all the input. I'm definitely going to try to avoid pulling the drive if possible. But like AllDodge indicated, I thought there was a brass jam nut that threaded on to the cable housing that secured it into the gimbal housing. But as always really appreciate everybody's...

    Bravo Shift Cable Bellows Ripped in Half....

    Wow thank you Chris. Took me about 10 times reading that to figure out what your technique was but it all makes sense now. Brilliant. And the fact I don't have to remove the drive is quite a bonus, turning the job from a two man job into a one man job and cutting the time down immensely. Thanks...
