      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 .

Prop Question.

Recommended Posts

I have a Stratos 219F with a 175 Evinrude. It has a ss Renegade 13.5 x 25 4 blade prop. If I take off fairly hard on the hole shot it cavitates bad. I assume this is caused by having the wrong prop. Any ideas on what would fix the problem. The boat will do over 70mph on the gps, so I don't care if it gets slowed down a little. Thanks.

It sounds like you need to step down in prop pitch a bit... you should be running closer to 5500 - can you provide the year for your 175 evinrude and I'll double check to be sure, but you'll need to step down to a 21 pitch prop probably to get your holeshot back and reduce your cavitation.

Something is not right here. Running #'s you should only be running somewhere around 58 mph at 5000 RPM, assuming a 1.85 gear ratio and 10% prop slip. To get to 70 mph on GPS you would have to be spinning the motor at 6100 RPM, which is way too much for your motor. Your tach may be off and you are over revving your motor.

Anyways, this is happening to my boat also. I raised it up a hole to try to get some more RPM out of it. It worked I am getting 5300 RPM out of my 150 Johnson now, but blows out if I gun it out of the hole. Thinking of lowering it back down one notch. This is something else you could try. Check your #'s to make sure your tach is not off that much. Do not want to blow up a motor.

The motor is a '95'. The speedo shows that it is running right around 58 to 60 but I have been told the gps don't lie. What is the best way to check the tach cause you're right, I don't want a grenade on my hands.

I do not know how to check the tach without trying a different one. Hopefully someone will chime in on the procedure, because I would be interested also. I always thought GPS speed was dead on too.

Nice boat by the way. That is my dream boat. Seems no manufacturers make a fast walleye hull anymore. The 219f is a fast boat and yours has an old reliable v-6 OMC, which I also like. I still like old school things, 2 stroke carb is the way to go for me. Always get you back to the dock!

The motor is a '95'. The speedo shows that it is running right around 58 to 60 but I have been told the gps don't lie.

A couple of things:

1) For a 1995 175 hp Evinrude top RPM is 5500.

2) Are you sure you don't have your speeds switched around? Usually the speedometer over-estimates the speed and the GPS is lower, which is the opposite case this time. The other thing that makes me wonder this is that you're pretty close to Brent's speed estimate (thanks by the way) if your speeds are switched around.

3) I'd be surprised if your tach was off by that much. There are a couple of ways to double check your tach - get a hold of another one and plug it into the harness to see what that one says or get a hold of a meter that shows RPM based on timing. When tach's are off they're usually way off or off by 100 rpm at the most.

I know that I don't have the gps speed and speedo reversed. I also thought that was odd because boat speedo's are usually so generous. If it makes any diff., the boat does have a different speed pick up mounted on the hull than what came stock. maybe it's not calibrated properly. Next time out I'll check speed with my hand held gps to see if it matches and I'll see if I can pick up another tach to hook up.

Thanks for the compliment. I actually just bought the boat. I was leary of buying a 13y.o. boat but it is in almost showroom condition and with the economy the way it is I couldn't justify spending 30 or 40 grand on a comperable newer boat. Just have a couple of small issues to fix up and will then have a like new boat for 1/4 the cost.

    • Wow.....6th win of the season and it gets called ugly.......J/K. Getting down to the last few races and we have a pretty good battle going on for the top spot. I know I’m about out of decent picks left but we’ll see what happens. Good luck everybody 
    • Watched a nice 8 or 10 chase a doe back and forth for 45 min on Monday night. He checked her several times but she didn’t want anything to do with him. Few scrapes then showed up that night as well. About an hour north of the cities. 
    • Sorry but $200 seems pretty high for that thing to me. Thousands of less expensive alternatives.
    • Looks like a great project.  A DYI froth pak for $500 or so will do 12 sq ft at 1" thick.  Most home improvement stores carry these.  
    • I got a set of FXR FLoating bibs on clearance from the place in Rush City that goes along with my jacket I bought last year. It is really warm and lite.

    • Last weekend I switched out my ramp door for a bay window.  I'd like to spray foam it, but I'm sure I won't be able to find anyone willing to do it professionally in my area, at least not at a reasonable price.  Last winter I had to drive an hour and a half to get the rest of it spray foamed for about $2000.  One company told me they wouldn't fire up their equipment for less than 1800. For this small of an area I'm thinking I would be just fine with the foam boards @ 2-3/4" thick with the furring.  Otherwise, does anyone know how well those Menards Froth Packs work?  $360 still seems kind of spendy to spray foam that little area myself.  
    • That's awesome. I gave mine a test last night and they weren't bright enough. I might have to order some bright lights from Amazon. 
    • Looking good! I also wanted reverse lights. I used some of the really bright light bars from Amazon on mine.  
    • I would fur it out another inch, then spray foam and finish to the furring strips.  No vapor barrier needed at that point.
