340 oil Galley plug help?
That is just plain cool. Is it a jet? Tell us a little more about the boat.
When I saw the add for the boat I had to have it. 20 years ago I sold my 72’ Challenge Rally 340 slapstick, 355 rearend, black on black, she went like a bat out of hell and I loved her. Sold her to buy a house and start a family. When I saw the boat had the same engine as my Challenger I scooped her up. Sutphen boats are famous for there off shore racing boats. They made smaller ones like mine but not in high numbers. Sutphen must of worked out a deal with Chrysler to use there marine engines. Chrysler marinized many of there engines. Slant 6, 318 poly, 318,340,360,383,400,413,35? Hemi, 440, 426 hemi.
My boat has a Volvo Penta outdrive not a jet drive. I’ve seen these boats with both but the Volvo penta has a much higher top speed. Anything above 50 is fast on the water I’m hoping to get her to 60mph. I’ve seen guys do 70 and above in these smaller boats but they need big HP and bigger balls than I have.
I’m guessing my engine will be around 400hp. Will see how fast it will push the boat then go from there.
