Hey Mike, nice to ear from you, I hope you're doing better. yup winter are not fun when your a boat owner. This is a copy paste of our last conversation. Hey Mike, No apologizes needed, I hope your surgery went well and that you are doing well. If your starter is defective, It's very easy to change. Only 2 bolts to remove and 2 wires to disconnect. Just make sure to disconnect your battery before unscrewing cable on starter. I actually have a video where I remove the bolt and move the starter aside. The only thing is to unscrew the cable. see kzbin.info/www/bejne/eoaynKlrl6eagcU at 2:17 to 2:29 sec. I had unscrewed the starter bolts already just to make the video faster For the price of a starter it all dependent if you get it used or new. Shouldn't cost you more then 120$ us. But your starter might just be jammed, since it was not used for a long time. Anyway try starting it without the starter and see what happens. To bypass the starter use your pull rope to start the engine. Good luck and let me know :)

@joetheboatguy5394 thanks for this Joe. I'm just out but I'll check this again and thanks for posting old conversation! And does your video include the specific mercury part number so I know? Thanks again!

Hey Mike, easy way to find parts is on www.marineengine.com with your serial number you can find what you need. I think you need this one but it better you check with your serial number on the website www.marineengine.com www.amazon.com/Compatible-1980-2005-50-893889T-50-90983A1-50-90983T1/dp/B0CZK879W5/ref=sr_1_2?crid=1HGDUVI0418F3&dib=eyJ2IjoiMSJ9.GJjf3oQvd9S5GNm1CJJKlvQS_ABWuhOnSSNacFrQfB5_GZyenDiOoI_0J6SDCdr4340AJkS3JoqA5PZ-HmqkD93vlXzBb6kXX-COGus6YlHlJOKem31oRzCFYFLXseU5TDfBnfisPWb6wZFftNHoiPdI63cr5H8Nnn_07v2zdfs8SwovcxXADGzox7qGd-t0xmohTbK8iM11mRgZc8cB9av8gtPwJzyJM7PEvx-1IVg.L4cJQ_CozV6MHRB0_WmZLW9zzgtKtq8NpV56K9N1rVY&dib_tag=se&keywords=1989+mercury+25HP+starter&qid=1737764969&sprefix=1989+mercury+25hp+starter%2Caps%2C81&sr=8-2

@joetheboatguy5394 hey Joe. I actually have been using that site for this motor, and the 50hp I'm having those other issues with. The thing is, using my serial #, gives me a few options on manuals which i then open the tabs to find starter. In other words, I have 2 possible starter assemblies which are slightly different part #'s. The link you posted is one of them though. Thanks for all this help!

Hey Mike, when you’re gonna do your tests once you pump your fuel line wait a little before starting the engine to see if there’s any fuel that goes at the bottom of the engine. You might have a fuel leak.

Hi TheJimmyrazor, thanks for watching and nice comment. Yes it is possible to add a VSR for when your switch is set on Both positions. Now it depends on what you would like to do, To start is it a Dual or single VSR you would like to install? If its a single VSR what battery are you looking to protect more, I'm guessing your startup battery..... let me know :)

Hi kyleesimmons, thanks for watching. What do you see is the connector behind radio so all wires are coming out of the radio. For the turn on amp wire some amps have the to turn on function. That wire send the signal to the amplifier to turn it on or off. Hope this helps. 👍

Hi Cien_Swiatla, thank you for watching. Can you be a little more specific where the short circuits would be? Because this circuit has been created and working perfectly with no issues for years. Let me know, Thank you.

@@joetheboatguy5394 1:20, 1 side of the fuse box is not + and 1 -. 2:06 you just connected positive wire on 1 side of the fuse, and the negative on the other side od the fuse (cables no 7 and 8), 2:18 same thing (9, 10 & 11 wire), 4:07 and 5:00 again, negative through the fuse to positive.

OK, I see where you think the short circuit are…. Fuse box has one side negative and the other side positive the middle of the fuse box is where positive power passes that ends up on the positive side after passing through the fuse. So the negative side of the fuse box is like a bus bar

@@joetheboatguy5394 yes

In words, it’s a little hard to explain. I’m gonna do a little drawing. Give me a couple of days. I’ll get back to you soon, but believe me there’s no short. 😉 I will try again with words but like I said it the drawing will be much easier to understanding. The negative side screw of the fuse box doesn't touch the fuse at all. So all the negative are connected to the Negative wire like a bus bar. So this will be all the return of the unit you've connected. The positive wire of the fuse box from battery the big screw on top, is the one that connects to all fuses in the middle (like a highway) of the fuse box to then distribute to all little positive screws. So you can look at it like fuses are the exit to highway. So power come from big screw on top goes to all fuses by middle of fuse box (highway) and exit thought all fuse to positive little screw. The two inline little side screws are not connected to each side of the fuse. That would be a short like you say but the fuse box is not made that way. Hmmmm let me know if it more clear. But I will work on something to make it clear :)

Hi Frank, thank you for your comment, I do mention this in the discription of the video.... "A break before make switch can cause damage to outboard alternators."

Hi drivebyquipper, thanks for watching, for the vehicle side it can differ very much depending on the model of the vehicle. Some vehicles actually even require module installation. So it can get very tricky and some others are very simple installations .

lol Granted I am wiring things up today, It was a used sxs, so I wanted to re wire everything ,( it was a royal mess) But I think I will just put the VSR ground on a switch until I get a Reply. Love your videos by the way . ... My end goal is when we go on a trip camping I can charge my Jackery box with our solar pannels and use that to charge the sxs if needed. And also installing external jumper posts to the main battery for just in case to use my noco jumper pack. ..the aux battery should the the only one taking a beating for lights or radio, it will be our only source of music in the evening so what would you suggest to cut off the Aux battery so it don't completely die, it just shuts off the lights and radio ? two VSR ?

Hi diydancochran. thanks for watching and comments. You can use your noco 5x2 and hook up each lane of the Noco on each battery. Any two chargers with the same output voltage can be used in parallel, and both will provide load current as needed. The rule on redundancy is that each charger must be rated to supply the entire standing load, plus about 10% more to charge the battery when needed. So you can use your Noco 5x2 and you will get a faster charge :) hope this helps. Let me know how your project goes :)

Hi Ian thanks for watching. Yes, this is mostly Us and Canada. I will put a note thank you for the comment 👍

Hello carischmiedeke, thanks for watching and comment. Did you try watching it on a computer screen? I do agree might be small at iPhone or android phones 👍

Hi tylerdifranco, Thanks for watching. It all depends on your setup and equipment connected to your batteries. But the best way is having both negative batteries wires going to bus bar. But both ways will work if you have the right gauge wire everywhere.

Hi Guerrero, thanks for watching, The only difference between 7-Way Utility and 7-Way RV is the color of the wires. The pin outs are the exact same so either would work just fine with the other. For RV it’s usually Green-Tail & Running Lights Black-12V Power Yellow-Reverse Lights Brown-Right Turn & Stop Red-Left Turn & Stop Blue-Brake Controller Output White-Ground

Hi DavidPyle, thanks for watching. I use paint in Microsoft windows. And then use a video software with iPhone..

Thanks, appreciate you watching! 👍

Hi Love-r5h, thanks for watching. Yes, The illumination wire can be plugged on the parking light wire if you can find it, that’s where it usually goes.. 👍

Hi huanqingwu, thank you for watching, When you press on your breaks, both the green and yellow wire will send a constant 12 V at the lights, that will mean that your brakes lights will be on. When your right flasher on your vehicle is on, your green wire will receive a on and off 12 V so it will make your light flash Same goes for the left side with the yellow wire. Now, if you have your brakes on and your right flasher on at the same time. Your green wire will receive on and off 12 V, and your yellow will have a constant 12 V. So the right side will flash and the other side will be constant On. Let me know if this helps 👍

hi kayingyang, thanks for watching, I talk about the ground wire at 1:00 to 1:30 sec check it out 🙂 I know putting the ground to chassis is not the best way but 95% of trailers are done this way. 👍

Hi Sveaisland, check out this website let me know if this helps 👍 www.seawaymarine.com/pages/mercury

Hi VijayGocool, you can add 1-2 switch if you really want protection. But your solar panel should have a diode that will let voltage travel just one way. So your panels would only really work once your outboard is off. Hope this helps.

Hi zv5231, thanks for watching and nice comment. Ok if I understand, you want to install your radio in your RV but be able to use the power from the vehicle battery unless your parked and unhooked from vehicle. If that is correct, then you want to connect your yellow wire to the leisure battery that is always in your RV. When ever your yellow wire is disconnected you will lose your setting in radio (like clock or programmed stations) that is why I say to have it connected with the RV battery 👍 Hope this helps

@@joetheboatguy5394 Thank you, the best thing to explain is to send you this link, it explains what I am trying to do. kzbin.info/www/bejne/qGOYZoicjMxoo6c Is the red wire only a signal to turn on the radio and most of the power is coming from the yellow wire or is the majority coming through the red wire? What I am trying to ask is if I leave yellow connected to the car battery and red is feeding from the leisure battery via a two-way switch is it going to drain the car battery or is the majority of power coming from red and yellow just to keep losing memory in the radio ect.

hello, Red wire will turn radio on and use more of the power. The yellow wire is mostly to keep your setting in radio, but without the yellow wire your radio will not start. Ok with your new explanation and video. I would connect the yellow on vehicle battery since in reality your radio will never be disconnected from vehicle battery. I though you wanted to install your radio in a camper with can disconnect from vehicle but that is not your case :)

@@joetheboatguy5394 Thank you for the great explanation and for taking the time to help me.

Hi 99tsr, thanks for watching, yes you can :)

Merci! 😊

Appreciate you watching! 👍

Hi pilipoff, thanks for watching. OK here we go, when you are set to BOTH position. startup battery and deep cycle it can be done but it can cause a loss of life of both batteries due to the differences in capacities and charge rates. That is why I say its not a good option but totally doable if needed. :) If I don't mention that it can possibly cause issues, my comment area would be full of people saying that it can cause problems LOL. So I mention it :)

@joetheboatguy5394 Thanks a lot! Finally I got an answer for the question 🙏

Good luck! Hope it goes well. 👍

Appreciate you watching! Glad it was helpful. 👍

Hi jonesey, thanks for watching. Your 12v aux is for whatever accessory you want to connect 12v to. The accessory that you connect your 12v to, will have a ground to be connected. Hope this helps 👍

Hi user, thanks for watching, don’t forget to subscribe 🙂. On Boats, Pink Wire is for a Fuel Gauge Sender to Gauge usually. Now it all depends on if it’s original wiring or modified wiring. Hope this helps 👍

HI christianchmielewski, thanks for watching and nice comments. Are all your separate circuit 12V, or do you have a 12V and 24V?

⁠Hello Joe, thank you for your answer. All the circuits are 12V. If you give me a possibility to Share a Drawing-File with you I can send you my actual Installation as a PowerPoint or a pdf file. Regards Christian

Hi Christian, I don't think its necessary to do it, but one simple way is to connect all your batteries grounds on one bus bar. Let me know if that works for you.

Hi Icwatts, thanks for watching , if you connect the power (+12) and the ground your needle should move to the E mark empty. You might not have the right sensor. So test only with power and ground. Let me know the result 👍

@@joetheboatguy5394 thanks for the reply! this gauge is on a '68 VW...its not marked as to what is the "signal" terminal, or which is the "power" terminal. no matter what i connect the gauge reads E

Try looking at this webpage, let me know if this is your gauge www.jbugs.com/product/113957063B.html

Hi brod. Thanks for watching both batteries will get charged, but since they have different amperage in the long run, it might affect the batteries. That’s why I put a charger with two outputs so each battery is independent on charging and you could have your switch on off so it doesn’t affect anything else on your boat also. Let me know if this helps. 👍

Hi boxout, thanks for watching. OK let me see if I understood correctly, so your lights do not have a ground wire. Is that right? if that’s the case, then the bolts of your lights are your ground which are connected on your trailer which is grounded that way. On your 4 pin in the front, of the trailer you still need to connect your white wire on the frame to ground the rest of the lights. Check the video at 1 min 9 sec, I talk about some lights not having the ground wire. Let me know if this is right. Hope this helps. 👍

@joetheboatguy5394 ya that's what I thought you meant thanks for clarifying.

Hey Mike, I see you did some good advancement. I will send you a video soon for the kill switch 👍 For the white wire I think it’s a tachometer wire you won’t need it if that’s the case.

Here you go Mike check this out: kzbin.info/www/bejne/q33de6SCn5yZeLM

For the gas line yes you can remove the end connector and put it in the mixed gas container. Only for starting and testing your engine. You can test your bulb once you put the line in Fuel tank, if it gets hard after a couple of squeezes your good to go. :)

Why would your black yellow stripe wire have a female and male connection is to connect multiple kill switch in parallel. Sorry forgot to mention that 👍

@joetheboatguy5394 thanks SO much for these replies and making a video for me! I'll review while in front of motor when I can. Thanks again for your generosity of time, Joe!
