These number are spot on for the engines that came in this boat. Verify if you would like 2003 Eliminator Daytona Tall Deck. Boat is 7500lbs with bbc fuel and me. Subtracted 1000lbs for ls setup. Hp numbers are all j607 standard. 1.36 gearing is what gearing was ran on the boat from the factory and used for bbc engines. 1.5 is what is on there now. Props are in accordance with what is needed and actually what came with those packages. VERIFY it I dare you. All with less fuel than all the rest. I figure a free tank of gas every 10 hours. Way less than the blower motors I pulled out.
Alot of research and thought went into me pulling blower engines out. I know some of you want to beat me up about this. So be it. Logic tells me this is the way to go. Will it be as fast as it was. NO. Will it accelerate as fast. TBD. Will it save me thousands of dollars in fuel. YES. Is it a mild build yes and payed for by soley parting my bbc. Will it work for everyone. No. But please do the math. The weight savings alone gains 160hp worth of speed in my boat. No money out of the pocket just shedding weight. And just imagine all this with no blowers, 60-100 ci less, and alot of room to grow.Yes a bbc can make more power. But try this with a comparable engine such as a 496 with stock heads and a cam and see how you come out. Thats all this is is a cammed stock headed stroker. Remember boys I have a car in my garage that is ls turbo making more power than many of your twins put together. I could easily mimic this in marine app. Why not. Because its not a biggest dick contest. Its just me documenting a build to help others who enjoy this or are considering it. I am not trying to come off as an a-hole just trying to do my end of the deal here. Good Day |
Can’t wait to see the results of them in the boat. Again good luck but you’d be the first to prove us wrong. Get em in and get some numbers. Also your first post said you’d make a 525efi look like a fool across the whole powerband. That didn’t happen. I’d take a 525efi over this any day of the week. Again most of us want to see an NA LS work but it hasn’t happened yet. |

BTW I understand you havent seen an ls get it done yet which is understandable considering there are probably less than 20 boats using them in sterndrives. Kinda hard to judge when playing with a unicorn wouldnt you say. |

Im surprised the twin LS package would be 1,000 lbs less than a 525efi engine. The ls engine is 500lbs lighter than the 525efi?

Where do you beat a 525efi? To me you are below it everywhere. Also forgive me I don’t recall but did you dyno in marine trim or dyno trim?
