    FS in NH - Alpha transom assy and carb'ed Bravo 7.4L

    I can help with delivery if need be. For anyone reading this, I'm far more interested in passing on a great deal to someone as I have limited storage when it comes to multiple engines and outdrives. I can move quite a bit on the asking price so please don't hesitate to send offers.

    FS in NH - Alpha transom assy and carb'ed Bravo 7.4L

    Misread the gear ratio back when I posted on 5-28. It's 1.30. Still unable to edit posts 1 - 3

    FS in NH - Alpha transom assy and carb'ed Bravo 7.4L

    Thank you. I see "Report" on the left side and "Reply" on the right side of the OP. Even crazier than that is, I clearly see the "Edit", "Delete" and "Report" buttons in post #3 but it does not exist on posts 1 and 2. Anyway, I wanted to say to any interested parties that I am willing to...

    FS in NH - Alpha transom assy and carb'ed Bravo 7.4L

    Prefer to sell as a package as I am about to install an MPI 454 and BIII transom assy and one sale/ pickup is desirable. My (completely negotiable) asking price is $2200. The Alpha transom assy is in excellent condition throughout and does not need a thing. The Gen1 out drive installed as a...

    Transom cutout - Alpha to Bravo

    Currently in process of converting my 268 Weekender from Alpha drive to Bravo. Heard a rumour that the only difference in the gimbal housing/ transom cutout are the addition of two holes in order to hang the Bravo gimbal housing, otherwise everything else is the same. Is there anyone here who...

    Free - near Concord, NH - Mercruiser 454 Alpha square port - broken

    Block is good, heads are good. Port head gasket let go and water mixed with the oil. There were women and children onboard at the time so I ran it toward shore til it popped. I believe a con rod snapped. The engine was at low RPM (1500-1800 ish) when it took its final breath. Poked a hole in...

    Pic wanted - B1 454 oil dipstick tube (cast aluminum pan)

    My "crimped" ferrule was actually painted into place on the dipstick tube. A pair of locking pliers and some light tapping set it free.

    Pic wanted - B1 454 oil dipstick tube (cast aluminum pan)

    Ordered a replacement oil dipstick tube for the B1 engine I am preparing to install and have a small issue. There is some kind of ferrule crimped on the tube that won't allow me to slide the nut down to the threads of the elbow that exits the oil pan. The old tube does not have this ferrule...

    Merc 454 Alpha​ catastrophic failure - I have a few questions

    To close this out for any future readers: Issue has been traced to an aft portside head gasket failure. Again, my apologies for jumping the gun with saying it was a fuel pump.

    Merc 454 Alpha​ catastrophic failure - I have a few questions

    I agree and have not gotten to a place where I understand the observations I made the day after the engine blew. The oil on the dipstick did not appear to be milky and it looked like the engine was overfilled with oil. A friend of mine was a witness to this. When we pulled the engine, there...

    Merc 454 Alpha​ catastrophic failure - I have a few questions

    Since pulling the engine and looking things over, I too have my doubts about a rebuild ever taking place. Maybe the seller misspoke or I misheard but I absolutely do not believe this engine was rebuilt. There are simply no indications this engine was taken apart at any time. Also, I can...

    Merc 454 Alpha​ catastrophic failure - I have a few questions

    As stated in post 6, the oil level was checked before the boat left the driveway. Please don't draw conclusions from assumptions. I did everything correctly for my safety and maintenance checks. After a few hours on the water I went WOT for a short amount of time then kept an engine speed in...

    Merc 454 Alpha​ catastrophic failure - I have a few questions

    In my case the gauge showed good pressure (40-43psi) since we were on plane for several minutes and turning 3000 to 3800 the entire time with the exception of the short visit to WOT. By the time I throttled down to inspect the engine compartment noises, the engine damage was already done. Yes...

    Merc 454 Alpha​ catastrophic failure - I have a few questions

    From what I've learned, the mechanical fuel pumps for automotive applications have a weep hole in the pump body whereas the marine style does not. When the automotive style fails, fuel is dumped on to the ground. When the marine style fuel pump fails, the fuel dumps into the crankcase. The way...
