      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

Recommended Posts

Daze Off

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.

      If I remember right you used to have to get a license a while ago before they changed it to the if you occupied it rule. I don't think 14.33 a year is going to break anyones bank. Hopefully they use the extra money for stocking purposes

      Yeah looks like the 2nd weekend in December if we're lucky before you can ice fish this area. Going to be another late year on the ice.

      It just never ends in this state.  Tax, tax, tax.  Where does this money go?  Whats next?   A tag for your vehicle to drive on the ice?

      Fun for some folks that went exploring early ice from a few years ago.

      Hi Cookie,  a buddy and I are going up this weekend.  Will they bite much after dark or is the water too mucky this early.  I appreciate any info.  Thanks

      Yesterday the MN DNR announced a license requirement change effective NOW for this ice season. All Wheel House and other fishing structures which cannot be folded / collapsed must be licensed even if you remove the house when you get off the ice.

      Harvest climbs 16 percent from 2016 Minnesota firearms hunters registered 161,057 deer through the third weekend of deer season, according to the Department of Natural Resources.  Preliminary results through the third weekend show that the number of deer registered was up 16 percent from 2016. Of the deer harvested, 53 percent were bucks, compared to 63 percent during the same period in 2016. In Zone 1, in northeastern Minnesota, total firearms harvest was up 36 percent. In Zone 2, which covers the majority of the state and runs from Canada to Iowa, harvest was up 10 percent and Zone 3, in southeastern Minnesota, was down 5 percent. “The conditions were generally good for hunters participating in the last week of the Zone 1 season and for the start of the 3B season in the southeast,” said Erik Thorson, acting big game program leader, “which provided a boost to the statewide firearms harvest.” Based upon the number of antlerless permits available and the number of permit areas that allow multiple deer to be taken, the DNR is projecting the 2017 total deer harvest to be around 200,000. The 2016 total harvest was 173,213 and to date firearms and archery hunters have harvested about 180,000 deer this year. In much of Minnesota, the firearms deer season ended Nov. 12, and the northern rifle zone season ended Nov. 19. The late southeast firearms deer season is open through Sunday, Nov. 26. The muzzleloader season begins Saturday, Nov. 25, and continues through Sunday, Dec. 10. More information on deer management can be found at mndnr.gov/deer. Discuss below - to view set the hook here.
