      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 .

short shaft conversion and water pump problem?

Recommended Posts

I have a 1980-81 9.8 Mercury and the last time I was out I ran through a shallow, gravely spot. Fortunately no prop damage but I noticed later that when I throttled down to trolling speed, the motor quit pumping water out of the pee hole blush.gif. It pumped great at high speed but only when the boat was moving. I'm assuming that I damaged the water pump impeller and need to replace it next spring. Is this a job I can do without a repair manual? I'm handy with tools but I need to know if there are any pitfalls to watch out for. The motor is a long shaft which is part of the reason I hit the bottom. How difficult would it be to convert it to a short shaft? Can I just switch the bottom end from a short shaft motor? Anyone have a short lower end to sell or trade? I've got all winter to decide what to do which means that I'll be frantically taking care of this at the end of May. Any and all advice, whether followed or not, is greatly appreciated!

Go to partsexpress dot mercurymarine dot so on and so forth. They have a schematic/drawing of the motor that shows what goes where.

Does your prop seem to be too much below the keel of your boat. A short shaft may put your prop above the water line of the boat.

Measure the height of your transom where motor hangs.

It can be for 15" (short) or 20" (long) shaft. If you have Long (20") you cannot switch to short shaft or your motor will be out of water almost completely.

If you need to reduce your height, you will need a new/used lower unit or take it to a dealer and have driveshaft switched to short, also if your middle section does not have the "long shaft" removable section, it witll be impossible.

Either or it will cost you more than the motor is worth, and by a long shot.

There are devices out there that help saving propeller, and lower parts of motor, from hitting bottom.

Replacing water impeller doesn't cost much, if you learn to do it yourself it will be A LOT cheaper.

Finns and Valv,

Thanks for the quick replies. I should have mentioned that my boat is an old 60's Starcraft aluminum and my short-shaft 5.5 Johnson fits it just right. I have a 2" board on top of the transom with the 9.8 long-shaft but it's still too long. Unless I run across a cheap short lower unit, I will have to just be more careful. Now I have all winter to find the parts diagrams and figure out how to tackle the job in the spring. Now if I can only dig out my portable buried in the garage....

      Best wishes for a happy retirement Ace.   I could never have done the guide thing even if I were a good enough fisherman.   It takes a special type of person to deal with all the different people... Congratulations on a job well done.

      Terry, Sorry to hear that you have to retire after all of these years! I suppose It will be my turn to join you and Tommy before to many years also. See you on the water!! Cliff

      Congratulations on job well done sir. Your deserve time for yerself with Sandra an the whole younger crew. You have always been nice to me an a big help when I first seriously did the Muskie fish guide deal back summer 1996. We have had some fun times laughing online an in each other's boat over the years. Even boated a fish or three an coined a few major phrases still used in today's ever so silly online Muskie fish market.  Good stuff that I think only you n I could muster up and never take any of it seriously. Truely makes me smile clear to my middle all the junk we talked about an did. You are a good man Terry and welcome in my boat any time. Anytime. Ya done good and will not soon be forgotten. Thanks for being my friend on or off the water. The name fits as you really have been "The Ace"on our sweet Vermilion.   Still no fish round my docks but Bonnie, Polar Bear Boy an myself always have enjoyed your company. Yer the best in many ways my friend.  Thanks. Keep on Rocken!   Tommy.       PS.    I will continue to keep the Zombie Horde in check.    ; )

      Keep the reports coming Curt, much appreciated.  Unfortunately, I'm not able to get back up there until September 22-25th., so it going to be tough keeping my mind on work and not LOW.  Are you just moving around in the basin until you mark a school of fish, and then jigging them?  I see all of your waypoints on the screen you showed, so those must be spots that have held fish at one time.

      Hey everybody, I have my last two guide trips on the 22nd and 23rd of August. A bad back and old age have taken their toll and I will retire from a job I have loved to do for the last 27 years.  I still enjoy it but unfortunately my body just can't take the pounding anymore. I'll still be out there fishing but no longer on a daily basis. I will miss all the regular clients I have had over the years and all the new people I have met that I can call my friends. Thanks to all of you that have shared the boat with me over the years, I hope you all had a good time. "Ace"   "It's just fishing man"

      Bought a couple of baitcaster reels..my first....Lew's BB1 speed spool and Daiwa Tatula CT R. After about two weeks of daily practice casting in the river behind our house....lots of backlashes(birds nests)...I gotta say, I've come to love casting with these reels....much more accurate than my spinning reels. Any other baitcasting fans out there?  If so, what do you use?

      How's the bite been recently.   Coming up for the weekend and curious at what depths to start at.

      On the lighter side, I am 'SpoonBillSlayer' on that other site. For whatever reason years ago when I joined these sites I used two different userids. Both odd duck names that fit an odd duck! I just wanted to get the new updates out on this mess, it just seems like the only people being notified of it are those in  lake assoc's.  We'll see what happens.
