    Transom re-assembly in progress. Steering arm face up or down?

    The manual doesn't specify. So I wonder if it can work either way; depending on how your steering ram is installed. Manual pictures indicate it should slope upward when installed.

    How To Plug An Old Engine Into NMEA 2K

    Yep. And a huge advantage that the GFS-10 has over my Lowrance sensor is that it not only measures fuel flow but it ALSO monitors fuel tank levels and dumps that info into NMEA 2k. Two birds. One stone.

    How To Plug An Old Engine Into NMEA 2K

    Thanks and good point. I actually don't mind a lower refresh rate w. digital. Accuracy, yes. That would be more of a problem. But really I like the thought of being able to manage everything through one multi-function display. Not only does it save on real estate, but then you also have the...

    How To Plug An Old Engine Into NMEA 2K

    Hello All - I have a carbureted '93 Mercruiser 7.4 engine and I'd like to use the NMEA 2k network to monitor things like RPM, oil pressure, voltage, and water temp. Basically make my analog gauges obsolete. Apparently there are some devices out there that allow you to plug analog signals into...

    Distributor cap for 3.0L 181/L4 engine

    If you have the Serial Number you can to to the official Mercury Marine website and launch the parts catalog: https://www.mercurymarine.com/en/us/parts-and-accessories/parts-catalog Put the serial number in, then you'll get some results on the window to the right. Should be under DISTRIBUTOR...

    Extra parts? Where do they go?

    This is what it *should* look like when these flappers haven't failed. This is looking down into one side of the exhaust y-pipe. This would be where the riser exhaust elbow would connect to the exhaust pipe. These flappers are like "one way" valves and they prevent water from coming back into...

    When I turn the key starter rapidly clicks

    People keep mentioning the battery and "bad connections". Regarding "bad connections", I've found that the main ground wire that's bolted to the flywheel housing in the back is oftentimes corroded. Remember, your ground is just as important as the positive. A quick trick is to take jumper...

    White Smoke on First Start on Muffs

    Typically, "fogging" the engine is part of a winterization procedure. *If* it is smoke (but looks like steam in the video), it's probably just the fogging oil burning off.

    '92 7.4 Carburetor Accelerator Pump Not Working

    My observation first started when I went to fire up the engine after a long dormancy. I went to "pump" the carb a few times to get a few squirts of gas into it. Noticed there weren't any squirts. Completely dry. I got a small atomizer spray bottle and sprayed gas that way, and got the engine...

    '92 7.4 Carburetor Accelerator Pump Not Working

    1992 Carb'd Bravo 7.4L (Weber/Carter AFB?) I haven't run this boat for a couple years and now that I did, I noticed there isn't a jet of fuel when I manually apply quick throttle. But there isn't much of a hesitation, either. (Also there isn't a load; running it on muffs.) Are accelerator...

    1993 7.4L Gen V Fuel Pump Issue?

    Yep. I rebuilt one a few years back using this helpful Youtube video. Bought the bearings off of Ebay.

    1993 7.4L Gen V Fuel Pump Issue?

    Well now I feel real special. :) I removed the belt so that I could "dry" run the engine for 30 seconds w/o ruining the impeller. Thank you!

    1993 7.4L Gen V Fuel Pump Issue?

    Hmmm. That's a good idea. I can buy one of those fuel primer bulbs and apply pressure my own pressure. Do you happen to know the size of the fuel hose that fits on to the barbed nipple on water separator inlet? By the way, I painted the whole engine this color so it *could* be the original fuel...

    1993 7.4L Gen V Fuel Pump Issue?

    The water separator? Yes, was full. Didn't take note of the in-line fuel filter in the fuel hose coming from the fuel tank. I *should* have looked. :( Note that this engine hasn't run in over a year.

    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...
