smbass77.
Hi guys,I got my first BCB a couple of weeks ago and have been having lots of fun learning to drive it. Now that I a getting comfortable at 70+ mph and correcting chine I am starting to wonder a bit about the best set up. Its a 12 eyra with a 250 pro xs with 1.75 gears.its not the silver/ grey lower unit. Its black and says 225proxs1.75 on the sticker. 26 fury. 2 powerpoles, detwiler hydraulic plate. Anywas. Seem to be topping out at 75mph. Thats with two guys, gear, and both gas tanks full to the brim. It seems at 5800rpm I am only getting 71 or so. I really have to push it up to 6100 to hit 75. The boat comes out of the hole like and animal with the 26 fury even with the full load and full gas tanks. Should i I be stepping up to a 27 fury?sacraficing a bit of holeshot?Is that going to get my speed up and revs down?Im in Atlantic Canada, and the water is fairly coolyear round, not sure if that matters or not, But I read about people using different propsin the winter. I wont have that problem. Thanks for the advice. I have played with the jack plate at different levels trying to get an extra mile or two. I find the optimal level is about 2 inches up from bottomed out. The he engine is mounted on the middle hole. 3rd out of 5 holes. I am deffinetly willing to sacrifice a bit of holeshot to get the tournament load speed closer to 80. And i I dont want to have to drive it at 6100 on long runs to get 75+The prop was not been worked on professionally. Thx
Thats about the best Ive heard of loaded with a 225.
Its a 250 pro xsThe lower unit on the motor isnt the original. Its quite new. There is a very small sticker on the lower unit that says 225proxs. 1.75
It sounds like the engine is too high and the tachometer is probably analog and not exact, which we feel is too high on indication.
Sounds like its too high. Your getting to much prop slippage. Start lowing it 1/4 inch ata time till you find the sweet spot.
If your rpms are correct I would think that you may need to try to lower your motor a little to gain more speed. Looks like a good bit of slip. At 6100 rpms and a good 26″ fury you should be running in excess of 80 MPH. Most people new to a basscat hull tend to run with the motor too high and/or over trim causing excessive slip. On my 2014 Eyra/250 pro xs combo Im running a 25″ fury at right at 6000 rpms and seeing 79ish with a full load of gas/ tackle/ and me alone. With 2 people and a full load its 77ish. I have broke 80 a few times with the 25″ but only under optimal conditions. A 26″ fury has been my fastest at 81.6 but not repeatable and the hole shot for me was unacceptable. I could only turn the 26″ about 5850 at best. Again, especially if you dont have a tourquemaster lower unit, lower is better on engine height. You should be able to tell if you have the tourquemaster by looking at the skeg from the back. It will have a definite flare to the right which is the tourque tab and is designed to provide more secure handling at speed.Chris CoupelPaulina, La.Chris CoupelPaulina, La.
Thanks everyone for the info.I was able to gain another 2mph to get upTo 77. And still tinkering. Final question. So, I read a lot about people saying that bass cats like to be run lower than a lot of other boats. Say maybe 3.5 below pad compared to 2 inch below pad. Why is that?Is it just because of the fury prop itself likes to run deep. Or is it becauseOf the hull design?I know people talk about slippage with the fury if its run a little to high. Say two inches below pad. So why not use a bigger prop that wont slip?Just curious. Everyone seems to want more speed. But everyone says to run a fury deepIt seems to be counter productive. I would think youd want a prop that would allow you to lift as much of the motor out of the water as possible while still having a good bite on the water and getting enough water pressure. Dont get mad ! Im just new. And trying to understand why people want to go fast. But run a deep prop with more motor drag. Thanks for your patience, And as always thanks for the input and advise.
http://basscatowners.yuku.com/topic/122 … ine-heightWe think most boat owners run their engines too high on almost all brands. From our experience we fund this. We have suggested many bass boat owners of other brands lower their engines and we have received phone calls afterwards of appreciation. A simple rule of thumb is that if you have a boat that is hard to steer with torque pulling right, the engine is too high.
Hmmm, maybe I should lower mine a little more too. Im hitting 72-74mph with my Eyra on a full tournament load with two guys. It may go faster, but I tend to pull back over 70mph haha. Still trying to get used to that speed as my old Skeeter was a dog and topped at 63mph
