where are you fishing. i haven't fished the western basin lately but back when I did after the jig bite was over most boats started trolling. when I started back in the early 80s most did cast and count down but all we dit was let out a lot of line off our spinning reels and just drift, and very few days we didn't get a 4 man limit. but later when the water cleared and not as many fish we switched to trolling.
But later, we started fishing the central basin out of Geneva, Ohio, and trolling was what everyone did. i believe a few guys have been drifting in the central basin since the great influx of new walleye but I have no idea if they are catching walleye.
i thought the whole purpose of using fluro was so you could use heaver line without spooking line shy fish. if 8# fluro is invisible wouldn't 15# fluro be just as invisible?
I went to 20# seaguar premier leader line for my leaders trolling the very clear water in the central basin and I have never looked back and didn't notice any less hits than I was getting with 12# fluro leader. i did this after having 2 huge fish break my 12# leader in rough water.
the 1st bait would be Steelhead killer and still catch walleye trolling the central basin of Erie out of Geneva Ohio. and I wouldn't count the last out until I gave them a good try.
when we went to the central basin at Geneva Ohio to fish for walleye. we didn't have a clue about fishing there. we took a charter out and he started letting us help by lunch time. the 2nd day he set the lines and then turned it over to us. if we had a big problem he was there to get us going again. on the 3rd day, we were on our own running 3 dipsies per side. We did manage to get some whopper tangles, but it was usually caused by doing something wrong. However, we did enough on the charter to be able to fish on our own and catch a lot of fish.
the charter we were on put us through school so I'm 95% sure if you ask around you will find a caption to take you out and let you do the rigging plus you may get some good advice that will help you in the future. but the most important thing is he fishes almost every day and could put you on fish and tell you how they fished and what worked for them.
if you go out on your own you may spend half of the day searching for fish. I feel 100% that your catch rate would double with a charter. his recent time on the water fishing would help you get started fishing without searching for the fish. i wholly recommend you find a charter willing to let you fish on your own without any help other than his advice you would be so much better off.
after using 13# pancake weights for years, we forgot to load them in the new to us boat. we found a pair of 8# dredge weights and had no choice but to use them. I was amazed at how much less blowback we got with the 8# weights over the 13# pancake weights. i have purchased a set of 10# dredge weights but haven't got to use them yet. i don't know if the side fins pull them down, but I'm a believer in the dredge weights. also called Herbie weights. hope this helps give you a little insight into weights with side fins.
I was using 13# pancake weights and forgot to load them in our new used boat. found a set of 8# herbies and had to use them. To my amazement, they had less blowback than the 13# pancake weights. I went on to buy a set of 10#, but the 8# was working great. but I just wanted to see how the 10# blowback would be. I haven't had a chance to use them yet, but I'm looking forward to using them.
bottom line is the pancake weights are better than the ball weights, and the herbies are better than the pancake weights. I bought a set of 10# weights off another member on this site.
If the jack plate you use has at least 5" of lift, I can't think of any reason it wouldn't solve your problem. As the 25" is 5" longer, if you can raise it 5", you should be good to go.
the dredge is the best I've used. I was using b13# pancake weights but had to use 8# dredge weights on one trip and had less blowback than the 13# pancake weights. I bought a set of 10# dredge weights but haven't used them yet.
you can't worry about the cost! if you figure all the costs involved in fishing and not catching you will never pay even close to the market as you will spend to go fishing. but that's just my opinion. LOL, for what it's worth.
I look at it like this if the rod is out the side it may have a little more stress because it's at 90 degrees. but I use Cannon ratcheting rod holders and can set the front one tilted up and the middle one tilted about half as high as the front one then the back one set at 90 degrees will spread the lines out at different angles, but that's using 3 divers per side.
I use 3 lite bite slide divers per side for walleye fishing on Erie. I run all of them at 90 degrees out the side and I don't have any lines tangled while trolling. I do use 3 different-length rods which makes it easier to read the lines. I have a 9' in front and the 2nd one is 8' set 20' less than the front diver set on 4.5 and the 2nd diver set at 3.0 then the back one set 20 less than the middle one and the diver set at 1.5 this keeps us from having tangles when letting an outside diver over the inside divers.
I'm just a bit confused by the 30 degree not being as stressful on the rods and reel seats. I would think the pull on the rods and reels would be the same as the 90 degree holders unless the 30 degree is 30 degrees straight back. I run 3 lite bite rigs off each side and I need the 90 degree holders to keep the lines from getting tangled. but that's just me.
I'm not trying to start a dispute about them just giving my input on my way of thinking.
it doesn't look like it's been damaged but looks like it's supposed to be there for whatever reason. if it's a new boat I would contact the dealer about returning it if you can't find out if it's a problem or not. I would either contact the dealer if it was purchased from a dealer or what I would do first is contact the company and ask them about the hole.
the easiest way to get an answer is visit a dealer that sells the same motor and look at motors on other boats. you know where to look so it would only take a few seconds to check other motors.
