      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 .

Water in the Lower Unit

Just winterized the boat motor 75hp Merc and found that water had infiltrated the lower unit at some point - any idea what kind of repairs are required and how much they might set me back? Never had this happen to me before....

Not neccesarily... it could be as simple as the prop shaft seal got some fishing line wrapped around it, cutting the seal. It'll require replacing, but way cheaper than replacing the entire lower unit.

I'd say replace the lower unit oil to cover you until spring for sure... if you're in the mood and a little handy take the lower unit off and into the dealer and have them take a look at it. They'll pressurize the lower unit and figure out which seal(s) are leaking.

Double check your plugs, both top and bottom to make sure they've got a gasket on them (and only one).. other than that I'd say it's time for a trip into the dealer.

It can wait till spring since you've replaced the lube, but if you take it in now you won't have to deal with it in spring.

If you are not up to the task yourself call around to marinas. I had Twin City outboard do mine for 200 bucks about 5 years ago but it had to be done over the winter. Marinas are real slow during the winter so you might get a better deal. Seal kit for that motor is about 30 bucks and a service manual is about 40 dollars. Good Luck

Thanks guys - I am not handy with engines at all - it was a big undertaking to winterize it myself this year (with help from neighbor) - always had it done by shop in past so will be taking it to a shop - called the dealer where I bought it who indicated it could be as simple as the prop seal ($150 P&L). So will try that route first and hope for the best.

Weird part is that I thought I saw water emerging from around the sacrificial anti-corrosive plate while we were running the motor with the rabbit ears to fog the top. Did not look too closely as I had no real reason to at that point. I remember thinking it must've been side spray from the ears.

I had the same problem this year with my 40 hp merc.Its wasnt just a little water more like a cup. No fishing line around the shaft either.I noticed the drain plug and fill plug had no rubber washer.I am hoping this is the problem.Is there supose to be a rubber washer? I know there's one on my 50 hp yamaha.

Make sure the rubber washer isn't just stuck to the lower unit after pulling out the plugs, too.

Yes, you ahve to have a washer to seal, as mentioned check if it's stuck in the therad of the hole, if not you've probably found your problem, and remember there are 2 plugs with washer, the drain/fill (bottom) and the overfill (top).

Daze, I had the same with my 25 Mer. All it was, was a prop shaft. Get the kit and the repair manual and you're in business. Manual is a good thing to have around. You'll be able to handle it just fine. I should add that it's not a bad idea to pay a dealer to pressure test it first.

if you run your motor with a broken or off balance prop,the seal can go out from shaft vibration also.

      Picked up some nice crappie and a couple eater walleyes on Allouez Bay the other day before the rains. Trolled crawlers with one light split shot and others with bottom bouncers. I was surprised at how big the crappie were

      ripped out some old boards that were well past their prime on my boat.  Any recomendations on what to replace them with?  They looked to be treated plywood but wondering if getting something different would work better.  Such as a piece of 1 x 12 pine and throwing a few coats of polyurethane on it as well?  The boards I am talking about are for the benches.   Also, replacing the seats in there as well.  Previous i had the the vinyl foam seats.  When shopping around i am seeing a lot of the molded plastics chairs.  Any preference out there for durability?  Vinyl rips but wondering if the molded crack or break?   Thanks for any feed back!

      The flocks of geese are now flying over my house in the morning and evening, but when this happens Finn gets all jacked up. Like right now he is nudging me and running pawing at the window. A few minutes earlier when the first gaggle few over I was going to change the laundry and Finn raced down and sat by gun safe  whining.  Fishing reports have been great for crappies on the area lakes. Walleyes are not biting as well in lakes but when the rum is clearer that is the place to be. Bears any no quota hunters this might be your year to get a bear around here.  Deer seem to every where drive carefull.  Seeing some ducks flying around.  I have seen a few grouse and pheasants.

      I've been by a time or two trying to figure out which place is yours.   I was out on wakemup last night too.   Got nothing, on crawlers.  Started out at merry go round, went to "picnic island" (little island east/south of taylors).  rigged along edge of those two humps in like 18-25 feet.   Musky guys were coming so I turned.  They turned too, chunking baits in the vicinity of my boat.   Then some guys in a pontoon pulled up and anchored in front of me  and threw out bobbers.   Fished a while longer, and it was getting sort of dark so went home.   Weird.  I've been on those humps a bunch of times this year, and suddenly I get company.   And, even though it is a pretty big area they gravitated to where I was.  I'll be out today too, so if you need help with supervision, let me know.    But I will drive by to check out the new construction.

      Been getting a few on the weed line, early am when there's a little breeze, since the surface temps started coming down. That was about this month's full moon, for me. A very slow troll, fishing vertically, & just a 1/16 oz. jig.
