      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

A quick question regarding my Mariner 45hp. issue

Recommended Posts

For the last 3 weeks. My 87' Mariner has been acting up. When sitting for a while....the engine has a hard time turning over. After cranking for sometimes 15 seconds it will SLOWLY start to putt into gear and turn over. It's fine and operational then and if I start it up again in less than an hour it turns right over. But a few times while running at slow speeds it putt's out like gas flow is stopping. I'm wondering if it is something that has to do with air in my gas or inconsistent gas flow to my motor. Any suggestions on narrowing down the problem?

This sounds real close to what my '96 25hp Evinrude is doing. From discussion here, as close as I can tell I will need to rebuild or at least clean the carb this fall.

I went through the normal "get new fuel line and bulb" and new gas and all the normal stuff, and it still is doing it. It is like what happened to my '94 Honda Magna a couple years ago, I think the carb just gummed up - after cleaning it runs like new again.

I would start with a brand new "merc" brand fuel line and bulb. The kind you get at FF or Wally world are far inferior, I know that one from experience... doh.

Good luck, those 45/50 merc/mariner motors are great, we have a '82 that we have not touched other than impellors so far, and plugs.

Carbs eh? That doesn't sound too good. The engine has been excellent for me and I've never had a problem until now....I will try out the fuel line and bulb and see if I can narrow it down from there. How did you go about cleaning your carbs a few years back BoxMN? I think I've only used a solution that you add to your gas and that seemed to really perk the engine up.

Cheers,

Yeah, do the cheap and easy things first, the fuel line and bulb.

For the carb cleaning, either bring it in to mechanic, or you can try yourself. I brought my bike into a mechanic and the job was like $500 - but that is 4 carbs on that bike, and I got a deal for doing it in Feb... nice. I then had to take off my carbs on the magna myself to find a fuel leak (old gasket) and that was a bigger job than any outboard carb, that I can think of, at least till you get to big v-6's or soemthing...

For my 25hp and when I get to the 50hp merc, I will just do it myself. It really isn't that hard, and after doing one I think it will be easier. Just get carb kit from dealer and ask for a bit of advice, and then go to town! smile I am doing my 25hp this winter in the garage.

I think the 45 mariner has two carbs, each supplying two cylinders, but other might know for sure and can also let us know if I am blowing smoke anywhere.... as I am not in any way a mechanic. But over the years I have serviced my own motors more and more, and for the common stuff they are actually pretty straightforward and not too bad to do, as long as you have the space, time and tools.

When I say clean the carbs, I am not talking additives, but actually taking them off, putting in new gaskets, cleaning out the bowls and new jets, etc. Sounds more complicated than it really is, though. But it could get messed up if you don't do it right, but IMHO, don't let that scare you. They are less complicated once you get one apart. Or else a couple hundred bucks will probably get the job done with a real mechanic smile

Good luck.

Cheers Box. Thanks for the knowledge. I think I'm going to look into the fuel line and bulb here tomorrow and take things from there. Replacing those wouldn't be a bad idea anyways since my bulb is beginning to crack.

Surface Tension. Yes sir, I am choking on the initial attempt if it's been sitting for more than an hour.

Like Bob said check the easy stuff first.

One more question, are you priming up the bulb before cold starts and after an hour of sitting is the buld still firm?

If the answer is yes, with the other info you provided, change the spark plugs.

i have the same motor I also had the same problems starting when it was cold and when it sat for awhile. you should go through your carbs you might have a sticking needle take the cover off and see if you have any gas leaking the bottom of your carbs should be dry. For your plugs they have ones that do not have to be gapped there is no tip on the right ones . carbs are very easy to do just take your time . Your motor might be flooded that is why it is hard starting.It might just be leaking alittle so you woundn't notice it when it is running

Surface, the bulb has been losing firmness after about an hour of sitting. I'll check out the spark plugs as they could be changed anyways.

Raymond, good to hear someone else has similar issues. You mentioned a "sticking needle" can you elaborate? I have noticed traces of gas in the water on occasion. You also suggested plugs that don't have to be gapped? Can you explain? Outside of routine maintenance I don't know much about it.

Thanks again guys!

The plugs simply don't have the little "curl" piece of metal. They just don't look the same for this motor as your normal car or other plug, so no need to worry about gapping them.

The needle is just one component of the carburator. Most likely, if it is a carb issue, is that you either have some debris in there, or more likely with this age motor you have some build up of "crud" or varnish that either clogs a jet or prevents the needle from doing its job.

The other guys know real terms and how to do it, but in a nutshell it just needs a simple cleaning by hand smile Nothing some small tools and carb cleaner and a toothbrush can't fix!

Just dug around and exposed the engine after work today....I did notice some moisture or gas buildup near the front part of the engine. Is this a sign of my carb leaking?

It could be, it could also be from priming your motor with the motor tipped up, and gas running out the front of your carbs.

Go over the fuel line all the way to where it connects to the fuel pump, see if there are any cracks, evidence of leak (dust / dirt buildup) and go from there.

If it loses prime after an hour it sounds like a leak in the hose or a carb job needed.

That fuel filter looks a bit aged as well. I would certainly think that a clogged fuel filter or weak fuel pump would cause those symptoms as well.

Thanks again guys. Just to give an update. I went over the hose this weekend trying to find a leak without any luck. I did notice that when I prime the bulb it barely takes in any fuel? With this problem recently uncovered, it leads me to believe that theres a leak that occurs between my primer bulb and fuel tank? I'm going to head to the shop to see if I can find a new attachment for the gas hose and a new fuel filter.

    • Well so much for the big storm around here. 
    • That's what it's all about right there. Father and son making memories.
    • When you sum up a season with those pictures, it’s hard for the Frozen Chosen to agree you had a terrible one.    VERY nice.   I can understand though, not getting to enjoy what’s there is almost worse than not having it at all!
    •   Don’t have find my phone turned on or whatever your particular phone’s location service is and your photos shouldn’t be geo tagged.   Sometimes when I get geo tagged text pics from others, I let them know.    I agree with Eyeguy, we’ve slanted just about every fish catching possibility our way and the internet forums are just another one of those tools.  But like a flasher for ice fishing, we’d hate to be without em anymore.  Everybody wants to know what’s going on.   But yeah, being careful with sensitive resources probably has led to less chat about specific lakes unless they’re the ones already being advertised on billboards.
    • A good way to wreck a lake is to put out "there is a hot bite" out on the internet.
    • Ufatz, Rockport is rebuilding, but they have a looooong ways to go. That’s actually what took up a good portion of my season this year. Lotsa people still need help, and it just didn’t seem right to be out chasing ducks when I could be helping people rebuild their lives. They’ll still be there next year Yes there’s still clouds of redheads. They’re too easy to kill. Problem was, those puddles love to hang out in the shallow marshes, and with the lowest tide I’ve ever seen, they were dry all week. Makes hunting real tough cuz they spread out in the big bays and it’s real hard to narrow down any concentration of birds
    • Do big bunches of redheads still hang out in the basin right in Rockport?:)   And how is poor Rockport looking these days? It really took a beating from the big storm. Didn't ever get around to hunting the area but spent two or three winters there a few years back. Lots of good fishing and pleasant weather most of the time. BUT it can get chilly!! Glad you had fun; it's always nice to see flocks of ducks even if you don't actually get a shot at them.
    • info speed, electronics, titanium spring bobbers, custom rods, inline reels, faster augers, plastic baits, sharper hooks.  fish dont stand a chance.   Speed of info probably the biggest factor. Pics on sites are great but cant share specific location or even the lake unless its a beast of a lake. I just heard last week that sometimes cell phone pics can be investigated to find gps location if a guy is knowledgeable in how to do it. Blurr out the background might not work before long. I think these type sites can still be good for tips but gotta be careful with location info. 
    • I had same challange. Went with a 12v temperature relay switch. Heater/Fans in my DIY wheelhouse now functions just like my home or RV forced air furnance. It comes with a small heat sensing probe i mounted on my upper air duct than set the on/off temperature so fans runs/stops when heat kicks on/off. Provides perfect comfort for $15.00. https://www.walmart.com/ip/bayite-DC-12V-Fahrenheit-Digital-Temperature-Controller-10A-1-Relay-with-Sensor/585224840?wmlspartner=wlpa&selectedSellerId=12524&adid=22222222227093022211&wmlspartner=wmtlabs&wl0=&wl1=g&wl2=t&wl3=213210114658&wl4=pla-345493512458&wl5=9019533&wl6=&wl7=9019476&wl8=&wl9=pla&wl10=117430032&wl11=online&wl12=585224840&wl13=&veh=sem   Sensor under foil tape   Took photo when furnace was off. Temp range -40 to 230 f. Spare probe to right of controller, copper tube is thermostat, black button is pilot iginter.   Total set up with 4 speed auto fan switch.
