    Trouble re-mounting lower unit

    Thank you Scott06. You nailed it. I had so much trouble keeping that water tube attached let alone aligned.

    Trouble re-mounting lower unit

    Thank you. That's what I am going to do next year. I already built a stand for the lower unit. I'm thinking I may just drop the lower again and pull the upper instead of trying to re-mount it again. Turns out my water tube came off. I dropped it half a dozen times and thought I had it this time...

    Trouble re-mounting lower unit

    I have a 96 Mercruiser 4.3LX Vortec 4BB Alpha one Gen two. I dropped the lower unit and installed a new water pump kit. I've done this a number of times with a gen one and never had any real trouble doing it without help. This is my first gen two. I put it in forward when I dropped it and made...

    Thank you Alldodge. Would this also apply to an Alpha one Gen II? I have been mistakenly calling it a Gen I

    What happened now?

    Thank you guys The crankcase oil and the gear oil in the out drive are both full. I'll pull the plugs and see if it's hydro locked. Do I need to drop the lower unit and manually try to turn the drive shaft to see if the gear case is locked? The old coil had some corrosion at the plug and I was...

    What happened now?

    96 Mercruiser 4.3 L 4bb V-6 Vortec with Alpha One outdrive. Put in new plugs, plug wires, dist. cap and rotor. It backfired once starting it but then started and went to a smooth idle. Sounded good. I let it run for 4-5 minutes to loosen up the oil to make it easier to extract through the dip...

    Trim troubles

    I thank you all for responding. The trim is working again but only if I jump it at the solenoid terminals. It still doesn't respond at all using the up/down switch on the shift control arm

    Trim troubles

    I assumed the noise was the sound the pump makes when its being powered and working. If that is not true, how would I test to show power to the pump?

    Trim troubles

    96 Mercruiser 4.3 L 4bb V-6 Vortec with Alpha One outdrive. The up and down trim switch didn't work at all. Tried jumping solinoids and didn't even get a clicking sound. So I replaced the positive wire from the battery and the big fuse on the end of it. Then I replaced both solinoids, made sure...

    Flames up when starting

    96 Mercruiser 4.3 L 4bb V-6 Vortec with Alpha One outdrive. Boat hadn't been used for about a year. Stored without gas. So two days ago I filled the tank, bought a new battery and it started up. Went to idle for a few minutes with the ears on and I shut it down. Today I cranked it over for about...

    Stuck in forward?

    Thanks Chris. I can turn the shift shaft 180 degrees easily and it remains in forward so I turned it as far as I could CCW by hand then put vice grips on it and managed with force to get it to turn enough to get it to neutral. I think the drive shaft was stopping me from inserting it and I...

    Stuck in forward?

    Have a 2004 Mercury 50hp 4 stroke EFI. Dropped the LU changed out impeller including base. Thought I had it in forward when putting it back together. Once together it stayed in forward regardless of where the remote was. Wouldn't hit nuetral or reverse. Dropped it again and put it on a stand...

    Problem removing Water Pump base on 50hp outboard

    I bought this engine brand new on a 17' Alumaweld and am still the only person to work on the lower end.

    Problem removing Water Pump base on 50hp outboard

    Have a 2004 Mercury 50hp 4 stroke EFI. Decided to change the bottom plate as well as the water pump base this year with my routine impeller change. I inserted a screwdriver in each recessed spot at the top of the base and started to pry. I believe it has been in there since day one because it...

    Shifting problems

    2004 50hp Mercury 4cyl 4stroke EFI on a 17' Alumaweld. I have a side mounted control box. Shifting has never been as smooth as I would like it to be even after I had a shop adjust the cables. According to my manual the adjustment didn't align the cables correctly but I assumed they knew what...

    Water in the Oil +

    Last year it overheated a few times. Once bad enough to melt part of the impeller and water tube. After fixing that I've had it out several times with no problems at all until now.

    Water in the Oil +

    By "pitch motor" do you mean toss it or throw it away? I mainly use this in the ocean and it has an open cooling system.

    Water in the Oil +

    84 Mercruiser 5.7l sterndrive, 4bbl, open cooling system. Last time out it back fired a couple times starting it and seemed normal running just above idle through the no wake zone. Once through I accelerated but didn't have enough power to plane out. Wouldn't go above 15mph. The oil dipstick...

    2004 Mercury 4 stroke, 50 hp, EFI won't accelerate.

    Motor starts up and idles fine. Put it in gear at idle and it takes off at about 2mph like it always has. No issues until I attempt to accelerate. Then it acts like it wants to go for maybe one second before it starts to bog down and eventually die unless I bring the throttle back to an idle. A...
