Determining RPM's at WOT

Question

traveler

Still trying to figure out prop/rpm issues...do I figure rpm's with the motor trimmed all the way down, or at some other position? I only turn 5000 rpm's trimmed down,( yamaha recommends 5000-6000) as I raise the motor the rpm's will come up, obviously if I raise it too high you can hear it rev as it isn't getting enough bite in the water, which isn't good for the motor of course. I understand theres probably a "sweet spot" where it will run it's best, but for determining if I have the right prop, where should I position the motor? It's a 150 v-max with a 21 pitch prop, btw.

There should be a "sweet spot". Figure max rpm's where you would normally have the motor trimmed when under way, or at it's max trim up angle without losing performance. As you get more bow rise from trimming up, you should feel the boat speed up. When it hits the max top end speed, check your rpm's. They shouldn't be over your max limit or too low. Actually your rpm's at this point should be at or very near to the max recommended rpm's for your motor. If it's over and your hole shot is pretty good, you could probably go up in pitch a step. Just be sure to use a GPS for your speed along with your tach to get acurate results.

Also, if your boat seems like it needs more bow lift (still alot of motor trim left), check out some of the nicer stainless steel props with larger cupped edges. These props are made to help lift your bow and not blow out as quickly. They also help bite the water better when cornering.

Shoot, I don't know? I'm actually looking at new props for my boat right now, but I'm not sure what I'm gonna get yet. It's tough trying to pick the right prop. I don't want to waste $300 or more! If it's possible, the best thing to do is try em' before you buy em'! Find a dealer that sells props around your area and ask if you can return a prop if it doesn't work. Some dealers will let you do this, if they know you will buy the right prop from them when you find it. Then you can see what prop suits you best under all conditions. Also if your looking for more speed and a higher pitch prop, check out the props with "PVS" holes, (I think thats what they're called). Anyways, the holes add more rmps at take off by areating the water so you can get on plane quicker, and don't affect top end performance. As for actual brands, I'm not sure, but a good starting place would be at a bass boat forum. These guys are always talking about top of the line props and how to get better performance. You'll find all the top brands listed and then you can look up more info on the different brands. Of course, unless you have a bass boat with a big honking motor, your not ganna want to get the higher pitch props those bass boat guys are running. But atleast you'll know some good brands to look at.

Good luck with your purchase.

      Set up deeper on rock reef for the rest of the weekend and only managed one fish (26" eye), missed a couple others. We wanted to stay deeper due to all the traffic on the lake. We did enjoy a good time at Fishing for Ducks, we saw a nice walleye pulled through the ice but it only measured 27.5". Talk about a bummer for that guy!

      Roads to the islands always need to be taken very cautious and I would encourage going with someone who knows the area..  I believe they were shutting down the highway H extension due to this recent weather we just got?  Plenty of fish and opportune situtations in the bay.

      Another crazy busy weekend is in the books. I really enjoy giving out my fishing/what's happening on the lake reports but finding the time has been tough. To say its a grind is a understatement.
       I can tell you again as the season winds down I'm never ready for it to end, as I truly love being out there in my trucks, moving houses, plowing the  hillmen highway, giving advise, helping other fishermen when they do something silly, Driving into a snow bank, dropping there gun down a hole or any other important object like there keys. Every year all the workers seem to get a little grumpy as fighting mother nature, going from sun up to sunset takes a toll physically and mentally. It also seems I ruffle a few feathers every year and its never my intent  so I have to chalk it up as a long season. If I stepped on anyone's toes it sure was not planned or intended as all most every day plan a turns to plan b and c. Mother nature dictates where I go sometimes as well as any plowed roads that can make our job easier. The cookie shuffle worked very well this year as I tell everyone that gets lost in my maze of trails. I'm not a road engineer.
       Man did we get overwhelmed with wheel house's this past weekend, any fish coming from southwest had to go threw a gauntlet of hooks to find my fishermen.
       I had two wheel house's  that I set up at the end of the hillmens highway and was surprised how bad they did. I guess I should of went south not east? The nw road has gotten to much to maintain, there's one lone house out that way that will need a new trail made .
       Its all started Thursday as jonnny boy and I prepped for the weekend with Joe, Zack, Adam and   his crew arriving fro florida. Zacks birthday wish was fishing red lake, they had a blast. They went to westwind where they enjoyed a fish fry, plus they took home a few fish with a couple even getting a ride in florida fish house as we moved a small distance to put it on fresh ice for there last night sunday. Last year when they came we landed on the elusive yet still catchable upper red lake crappie mother load? I think  they had dreams for a year of repeating that. Every year is different and again this year was no exception.
       Ben who proposed in old Minnesota to Shawna 8 years ago were in old Minnesota with there two adorable kids. Louie the fishing machine and his little sister Willa plus there friend Nelli.
       They had a blast also with Shawna getting a elusive yet still catchable upper red lake crappie to boot. They also managed to take home a nice batch of upper red lake walleyes.
       Hunter and his two buddies were in north Dakota. It was slow but they also managed to take home a batch of fish.
       Charlie and Rizzo were in montana , They were very serious about there fishing and went home with there 8.
      Jeromy and his gal were in north Carolina Saturday, sunday . They also managed to get there 8.
       Sunday was a very tough day as we had all 5 houses re rented. I was planning on moving all of them so we battled mother nature the whole time as a ne wind with 2 inches of snow made it impossible to see. At one point I was getting sea sick as I struggled to see, With the sky, horizon and the lake all the same color. wow what a struggle.
       It took us  7 1/2 hours but we got every thing cleaned, moved.
       Mother nature has given us another bout of snow so tomorrow I will let every one know how the houses did the last two days as its time to check the fluids and fire up the fleet

      Figured I should report back... I fished prime time on Saturday morning and Saturday evening. No action. It didn't help that I forgot to grab the vexilar on the first outing, but it didn't help to have it on the second outing either! ha! Marked a few but couldn't get them to bite. Used a GPS chip to punch some holes over structure, but when I came back with the vexilar, they weren't quite as deep as I hoped. Thanks for the pointers BrianF

      Around this time last year this thread was started by @Royal_Dutchman. I got my trip planned for April but by the look of the extended forecast it's not looking to promising, especially compared to where it was at last year on Feb 23rd.

      Been a brutal hard water season for me as well, figured it was a continuation of my fall fishing luck.

      Thanks guys.  I checked out Modis for ice coverage and Navionics to help understand how things are laid out.  Knowing what areas certain fish prefer and those typical depths is a big plus.

      My wife and I are hoping to get up to Mille Lacs this Saturday and spend the night on the ice.  Does anyone have any last minute availability?  All the resorts I've contacted are booked. Thanks!

      Lots of nice fish!  Central Mn is cranking out some nice panfish.
