      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 .

Yamaha F115 4 stroke trolling speeds

Recommended Posts

I have a Lund Mr Pike 18 and the 115 Yamaha 4 stroke. I can troll down to 2.8 MPH minimum. (No wind or current) Is this what others are experiencing? Would a different prop allow me to get to my desired 2.0 MPH target? Thanks!

A smaller pitch prop would help you get a slower trolling speed, but you're going to sacrifice top end performance, which is more important in my opinion - if you change to a lower pitch prop you'll have awesome hole shot but run a substantial risk of over-revving the engine, doing damage over time.

If you're motor is running where it should be at top end (up around 6,000 rpm) I'd explore a drift sock to slow you down.

I installed one of the hydrofoil / flip down devices ( I think it was a hydro-troll) and it slowed down the trolling speed very nice (Around 1 mph if I remember correctly) the problem is that I could never get it to come back up without breaking the shear pins so I removed it. Maybe a different brand of one would be worth trying??

Jonny P did some experimenting and switched to a 4 blade prop. I followed his advice and got a 4blade 17" pitch. Also asked the marine shop to tweak the engine a little. Anyway end result is 1.8mph to 2mph with engine just in gear. Hole shot is greatly improved and I only lost 4mph off the top end. I run a 1750 Fishhawk. Drift socks are also a must. Can use them for both drifting and trolling.

Leave the motor alone and toss out a drift sock. Just learned that trick this summer in Alaska trolling for Kings...

By the way, I have an F90 on a Fishhawk 1750 and can just barely troll down to 2 mph without a drift sock.

I have a 115 yamaha 4 stroke and with a 15" alum I can troll down to about 2.0 and with a 17" stainless I can get 2.2. If its too fast I drop the bowmount down and turn it sideways or however it gets the speed where I want it. If Im going with the wind and Im still too fast I drop out a small drift sock.

The 15 alum will over rev my motor at WOT and the 17 stainless runs at between 5800 and 5900 depending on the load that day.

Oh I forgot. If I fill both livewells I can slow the boat down a bit more.

Thanks for some interesting ideas. I'll have to pick up a drift sock. I'll try the live well filling and trolling motor down this weekend. I should be able to get there without tweaking the motor or prop.

What year is the engine?

I don't recall if the 115HP engines were capable of using the Variable Trolling Speed switch, but it may be something to look at adding. I have it on my 90HP tiller and I rigged one up for a buddy with a 75HP console and he loves it to death, as do I.

The 90 hp is the largest engine available w/ that option as of now. Sweet feature though, I wish my motor had it.

I have a 2002 F115 on a Mr Pike 17. I troll down to the 1.9 -2.1 mph range w a 13X19 prop. I pull # 7 Raps in the shallows and do just fine with it. That is with the motor just bumped in gear.

LMITOUT,

How did you rig this for a console version? Is this something easy to do? I have a F75 that was new this year, but is run remotely on a console. I also don't know a lot about this, but do a lot of trolling so please give some specifics on what it does.

Thanks!

Sure. There are two different VTS modules for the Yamaha tillers. One is built right into the handle and is flush mounted. The other one mounts externally to the handle with two screws and is a self-contained unit with a short cable coming out of it that connects to the engine.

What we did with that 75HP console I mentioned was to buy the self-contained VTS switch and then just extended the cables to reach the console because the factory wire harness is short (made for tiller).

I had some four conductor low voltage cable that I used to extend the factory harness by clipping the factory wire at a convenient spot, and then soldered in the extension cable between the connector and the VTS switch itself. The key is you need to retain the connector on the harness to make it easy. Don't throw it away after clipping the cable.

After extending the harness wires, route the cable back to the engine and plug it in! Take the hood off and look on the front/bottom of the engine block you'll see a white connector that is unused except for a dummy plug to keep the elements out.

The boat owner mounted the switch near the throttle control with a couple of screws and he said he loves it. I believe the switch was around $70???

It is truly plug and play!

    • This furnace has 2 pipes. The larger pipe about 4" is the air intake is supported through ring #29. The smaller pipe inside the larger pipe about 2" is the furnace exhaust connected through the larger ring #30 and screwed to the raised portion of ring #29. My furnace a vintage Hydro Flame Convection with dual direct vent, needed no power, and used a pilot light. Had the identical 2 pipe direct vent as yours. I built 2 rings similar to your drawing. Had 2 major issues: 1. Anytime the wind exceeded 20 mph, my pilot light would blow out even when the furnace side of my house was parked to the leeward side due to wind eddies.  2. At the exhaust cap which was about 1 3/4" from the side of the house would scorch the side surface above the cap and the moisture from burning Propane (1/2 pt. per 10#) would freeze on and below the exhaust when temp went -10 or below. Second year I re-designed using the Pipe Cap photo 1 from Menards for under $10. I cut off the bottom half at the black line and cut a hole on the outside flat surface for the exhaust pipe. This was my fresh air intake. Also filled the inside of the cap with a disassembled expanded metal filter from a motor home stove top exhaust filter.  Photo 1   Secured it to my house and ran the exhaust pipe through the hole in the end. Attached the exhaust pipe to a 2" x 3" aluminum gutter down spout used as a chimney. Photos 2 and 3. Totally solved my issues. You may also find a similar cap to photo 1 for the exhaust instead of the pipe. Most of the caps I was able to find had a 4" connection point so you would need to modify to 2" or whatever size you exhaust pipe is. How ever you do it, cover all openings with a screen to keep the Mud-daubers out as they love burned propane orifice area to build there nest.  Photo 2 & 3
    • sure looks like YHBB.  open fields and swamps close by? They like to hang out where the RWBB do.  Cannon SX30IS is pretty cheap online. 35 power zoom. good for still shots.   
    • Going to bait tomorrow with fryer grease, bread, dog food, cherry frosting, peanut butter, soft candies, raw white sugar, and popcorn. I am throwing everything at them tomorrow, hopefully the bears like the variety!
    • I don't know about that but I will certainly not write him off, if he can be a steady vet I will be happy. 
    • That's a great chicken recipe duff, but that steak n corn get my vote!! 
    • I was gonna say my yard has been thick with juvenile birds the last few days, always harder to ID birds this time of year. Had an albino something or other with a flock of birds, not sure I've seen an albino bird before. And just had a sharp shinned hawk hanging out on the branch above the feeders.  But I feed ALL of the birds......love them raptors. I will say the cowbirds around sure tolerate the dog or I getting pretty close to them.    
    • Had a decent trip.  We fished the evening of Aug. 9-Aug. 15.  Had 2 pretty good days, 2 bad days, and the rest were just so-so.  Dad, Uncle, and Grandpa don't like getting up early anymore so we usually outdrink the fish at night and sleep in mornings.   We have slowly been learning how to consistently catch fish on this lake.  The local guys don't provide any information and neither do the guys that have been making the trip for 20+ years.  Can't say I blame them much, but would have shortened the learning curve for us a little bit.  We found a bay a few years back that we can catch 10-16" walleye all day in, just a shallow weedy bay pulling spinners.  Usually get enough eyes' for dinner and then go search the reefs, shorelines, and islands for bigger fish.   I think we finally dialed in on some bottom bouncers and have 2-3 spots were we can go and most likely catch fish with the chance at some big ones.  1oz to 1-1/2oz BB with leeches or worms work the best on these spots.  2 spots are reefs topping out at 9-10fow and the other spot is a little flatter, with access to some shallow weeds.  We also deep troll suspended fish some evenings and don't catch a lot, but the ones we do are bigger fish.  We found iwe caught more fish when we were running and gunning.  Fish a spot for 20-30 minutes and then move on until we found some fish.  This kind of stinks for Grandpa but he understands we can't catch them if they are there and active. Biggest of the week was 26 1/4" walleye with 20-25 eyes' over 20".  I think I had 2 -25" and also a 37" pike the last evening.  Really fun time and scenery with the family.  Looking forward to next year and searching more of the lake.
    • Not a cowbird. We have several around here and they are generally dark-black grey and brown. The pictured bird almost looks as though it could be an immature yellow headed blackbird. Cowbirds are quite reclusive and we have been surprised they come out to our feeders, but they have become pretty regular customers. Like the deer that graze in the front yard. Last night we had the buck, doe and twin fawns and even though we talked softly to them they did not spook,  but seemed to simply acknowledge our presence on the deck and continued to feed. And of course, as usual, the black squirrels are gathering all MY walnuts!  darn.....I just can't win. The chipmunks eat my strawberries, deer eat tomato plants and squirrels eat my walnuts. I'm left with this old bottle of Beefeaters, a small bottle of vermouth and a few olives in a jar.  Things are tough out here in the wilderness.
