It was not gone, because I still had to correct constantly, but it only required very slight movements and not nearly as many. I still had to correct constantly but not nearly as much and when it hit 75 mph and then 76 mph the walking reduced further. When I raised my Torquemaster to about 3.25" below with the 24P ProMax, the chine walking improved noticeably. However, I am sawing the wheel to control the chine walking all the time. After 70 mph I am steadily correcting the wheel but I never have to lift, unless there are cross waves, or very rough water. If my boat is at 70 mph or below, there is no chine walk at all. With a Sportsmaster you typically have to run them higher to reduce the drag? When I ran my plate higher with the ProMax, there was definitely less chine walk. I have owned performance boats in the past, where raising the lower unit so the prop shaft was even with the boat bottom, eliminated all the chine walking, and running it 2 - 3" lower caused violent chine walking but every boat is different of course. I think, but not certain, that some of the Verado's also had that same mid-section depending on the year? I assume that your 400R has a Sportsmaster lower unit so how high do your run the propshaft below the bottom? I have seen other members post that when they switched to a 400R / Sportsmaster their chine walking was reduced. Never considered the setback contributing to it, but perhaps it does? Do you have 6" of set back from the jack plate? If so there is another 4.5" built into the 400R midsection so you would have about 10". However if the speed is almost the same, (it probably accelerates slower with a 27 pitch versus our 24 pitch), if it handles better, they quality is better, and it is all composite, those are all good attributes.Ĭlick to expand.Interesting. Not enough trim or engine height could also increase the slip %. I wonder if that is due to the notched transom or just engine height / trim adjustments. Of course the people testing the Caldwell boat might have had the jackplate or trim not adjusted as efficiently as possible or the engine might not be broken in but since it turned 6300 rpm, the slip is much higher. So the prop slip on those two boats is around 10% and the prop slip on the Caldwell boat was 20% with the same style prop but more pitch. The new owner of Tom's 2020 BRX / 300R (last Bucyrus boat) said he had to get out of it at 73 mph due to chine walking but once he has more seat time felt it would run close to 75 mph. My 2020 Buycrus 24 Pulsare / 300R runs about 73 - 74 mph with a 24P Bravo FS prop. I assume that is the Pulsare with the composite construction and notched transom? They claim it drives better with less chine walking. You have to pay $90 - $120K for a decent Tri-Toon right now as well. However, in Caldwell's defense, I think the price of building boats has increased significantly due to shortages and demand. However if the speed is almost the same, (it probably accelerates slower with a 27 pitch versus our 24 pitch), if it handles better, they quality is better, and it is all composite, those are all good attributes.ĭid you see the list price at $126,000 !!! The guy that bought Tom's BRX told me he could not be happier, and looking at the upcharge for composite, and better handling, better quality, it would be a tough pill for me to swallow.
