    What is this?

    Thanks for the comments folks. Turns out it is the connection for my 12V cigarette lighter adapter.

    What is this?

    Whatever that is, it’s definitely burned up. I’d like to replace it, but I don’t know what it’s for, so I don’t know what to troubleshoot.

    What is this?

    I’m having a hard time finding anything called a switch contact to purchase. Is that something I could buy by itself, or would I need a whole new ignition switch?

    What is this?

    I connected my batteries to a jump box after the boat was sitting for awhile, and the starter was working fine initially. Then it just clicked like the battery was low. I checked the voltage and it was 12.8 when key not turned and 12.6 when key turned. I connected my remote starter switch, and...

    Electrical not reaching panel

    Sorry I haven’t gotten back to this, I’ve been away from the boat for awhile. I pulled the while starter out, and the starter is bad. Here’s a little more back story. There are quite a few problems, but I want to start with the electrical. In the off season, I installed new to me exhaust...

    Electrical not reaching panel

    I have tested the batteries and alternator. They’re not the problem. I wish it was that easy.

    Electrical not reaching panel

    I have a mercruiser serial number 0F598365 in a ‘96 Searay where the electrical isn’t reaching the panel. When I put a remote starter switch on the starter, I get one solid click, but the engine doesn’t turn. I have 2 batteries with fresh charges. I ran it for a couple hours today, but it died...

    Exhaust component inspection due to slight overheating

    Are the $20/$30 thermometers on amazon any good, or should I opt for a better one? I don't have a lot of use for one outside of this. Where should I measure the temperature?

    Exhaust component inspection due to slight overheating

    I don't think it's the power steering cooler. I'm pretty good about cleaning it out every year. I don't think there's much I can open on the heat exchanger. I've never cleaned out the seawater pump since I've owned the boat (2019), and I'm not sure if the previous owner did. I think that's my...

    Exhaust component inspection due to slight overheating

    This is a saltwater boat. I'm not sure what you mean by WAG.

    Exhaust component inspection due to slight overheating

    My Mercruiser 5.7L MCM SN 0F598365 got a little hot this summer most of the times I ran it. It never overheated, but it was definitely in the hot range. I have a closed cooling system, and I replaced the impeller and housing at the beginning of the season. I just took off the exhaust risers, and...

    No purple and white wire for base timing

    I have a Mercruiser serial number 0F598365. It was starting hard, so I went to do the timing. It appeared to be off by 4 degrees, so I corrected it. It’s starting easier now, but I’m still not sure if I set the timing properly. I can’t find a purple and white wire to ground to set base timing...

    1999 8hp Mercury Can't get shift shaft to push in for neutral and reverse

    I have a 1999 8hp 2 stroke SN 0G765923 that I took the LU off, and now I can't get the shift shaft to shift in to neutral and reverse. When I spin it clockwise, it gets to a point where it stops. Is the cam somehow spun out of the proper alignment? How do I get the shift shaft properly...

    Unable to locate oil leak on 8hp 2 stroke Mercury

    The motor is a 1995 2 stroke 8 hp Mercury SN: 0G765923 . I got this motor as a kicker on a boat I bought last year. When I changed the oil for wintering last year, I saw a very trace amount of water in the gear oil, but during pressure tests it maintains pressure, so I thought it must be because...

    I want better speed and performance

    I have 1995 Sea Ray Overnighter that weighs in at 5,000 lbs with people full tank and gear.

I had one instance where I...

    Hard starting after engine warms up. Carburetor ID

    I have an MCM Alpha 5.7L SN 0F598365. After the engine warms up, it has a hard time restarting. It will, but I often have to give it a lot of throttle. I assume this is a carburetor problem. I’ve rebuilt a 2 barrel Rochester in the past, and I’m not too scared of a carb rebuild, but I was...

    Alpha 1 Gen2 MCM 5.7L dies when shifting

    I have an MCM 5.7 Alpha engine serial# 0F598365 that was dieing when I would shift from forward to reverse. I adjusted the shift cables, and now it dies when I shift from forward to neutral, and dies when I shift from neutral to reverse. I tested the shift cutout switch using a 1/8” alan wrench...

    MCM 5.7 Alpha 1995 Did I adjust the gear shift cables properly?

    I have an MCM 5.7 Alpha engine serial# 0F598365. I bought this boat last year, and it ran ok, but I had issues with the engine dying sometimes when shifting to reverse. I followed achris' video on how to adjust the shift cables, but I have a spring guide assembly on that assembly that I didn't...
