    Hey guys, Is there a guide/post on here for changing motor oil in Alpha one? I am about to dive into it, but I would like to know where the drain plug is, what weight and amount of oil it needs, and which filter it takes. I looked at my manual but it does not tell me where the drain plug is. I...

    Suddenly wont go in forward

    So I had my boat out and it worked great. I took it home and replaced some bad wires (purple / yellow) and the tilt battery wire. I put the boat in, put it in reverse and it works beautifully. I go to put it I neutral and it doesn't do anything. If I shut the boat down, and turn it on, it's...

    What voltage should electric choke get

    I replaced some burnt wires and re routed some wires. All works good but now the choke doesn't seem to kick on. If I recall correctly, if you work the throttle forward and back to neutral, it should have set the choke. I took the arrester off and it didn't seem to do it. What voltage should I...

    Where can I find electrical wire for mercruiser 470

    I am having a lot of wiring issues this year so I finally said screw it! I pulled the crappy wire mess that attaches to the wire harness and am redoing the bad wires, and then re routing it so its not touching the hot engine. I am almost done but I found that the purple/yellow wire that runs...

    How do you charge a second battery

    My second battery is not charging so I need to know the proper way to charge the second battery. Do I just run a line from the one battery to the other or do I run a line to the alternator? See my sig for engine info

    [resolved] white/green wire grounding issue

    As some of you know, I replaced a bad gray tach wire from the Ign Coil (-) to the tach. When that was done, the white/green kill switch wire was no longer mated to the gray tach wire. So i ran a brand new size 14 wire from the killswitch to the (-) coil. Now when I touch the w/g wire to the...

    My boat used to stall when putting it in hear. Now the boats not getting out of the gear I am putting it in after we adjusted the lower shift cable. Is there any other adjustments beside the brass cylinder that could be adjusted? I think the kill switch is not activating

    Question about Temperature gauge

    I got the boat in the driveway and I do not have a temp reading on the gauge after the engine warms up with muffs. Is there a test besides continuity that I can run to test if its the gauge or wire? I see a white wire coming off one terminal on the back, and I think a purple one (light maybe)...

    Can't seem to find a place to buy shift interrupt switch

    I am trying to figure out what is causing my boat to stall when putting it in gear, and I noticed my shift interrupt switch has two wires coming out of it. One is practically melted through and may be shorting. i made some adjustments to my lower shift cable, as it wasn't fully catching in...

    Where can I find the lower shift cable / interupt switch?

    Hey guys, I started a thread last year about my issue of the boat stalling when I go to put it in gear, and I was told to check the lower shift cable or the shift interrupt switch to see if it moves freely or if its worn out. I found some stuff in the manual of what it looks like, but not...

    Stalling when putting into gear?

    Hey guys, I bought an 1985 Imperial last year and had it out 3 times before winter hit. Next spring I am going to tackle the only problem that I noticed. When I go to put it in gear (forward or reverse), it likes to stall out. This is after its been running for 10 minutes too. The colder it is...

    How to winterize 470 IO 170hp

    I am winterizing the boat for the first time and need to make sure I do not forget anything. I assume just run antifreeze through the watermuffs and then drain the exchanger? I already put stable in the gas.

    [Resolved] anyone got a picture of their Mercruiser Alpha One?

    I am new to boating (owning my own that is) and I just bought an 85 Imperial 170HP I/O. I noticed my gas vent must be clogged so I took the engine cover off to troubleshoot it. While down there, I noticed some hoses that are disconnected. I ordered a Selic manual but who knows how long it will...
