awesome project but are you sure those cv joints will hold up? i have seen many failures in the marine world

Love it!
Great thread, as always. I used to run a repair shop for Makita power tools and I always hated those big drills that would break your arm when they jammed! I have those big, 4”* hole saws that will do it too! |
You make every project that I think is hard seem so much more doable! Incredible project.

CONGRATS on getting the engine in! Now comes the fun part!
Looking at your tailpipe holes, what are your plans to prevent water washing backwards into the turbine housing? |

Valid question. How do any of the turbo engines prevent this?

Exhaust are ready, this way I sealed big holes.
https://cimg2.ibsrv.net/gimg/www.off...121e1d27c7.jpg First I weld 12 degree angle parts to get tails in right spot. Engine is also adjusted to level. https://cimg9.ibsrv.net/gimg/www.off...02fabcfaf5.jpg 2mm thick silicon sheet, it can handle near 300C temps so it's good sealing material. It doesn't matter if some day there is little tailpipe overheating issue. Silicon is also very flexible and stretchy so it can be slip over pipe. https://cimg3.ibsrv.net/gimg/www.off...db40f65951.jpg https://cimg8.ibsrv.net/gimg/www.off...8405abef3d.jpg Stainless steel water cut flange push ***** lip against to transom, should be pretty watertight. https://cimg0.ibsrv.net/gimg/www.off...c9e34b9a19.jpg https://cimg5.ibsrv.net/gimg/www.off...c4917f08f3.jpg I try find black silicon but red was only available, color doesn't matter now because splash is so close. No time to lose! As you see, pipes are litte up in holes, there is little tolerance to adjust driveshafts more in line (lift splitbox side of powerline up) if boat needs bigger trim angle. Engine is now set 2 degree trim angle to get CV joints as little angle as possible. https://cimg7.ibsrv.net/gimg/www.off...10a527b720.jpg Carbon tube end turning to straight, there is special tool locked inside tube to get support for outer end. https://cimg5.ibsrv.net/gimg/www.off...dcb91664f4.jpg CrMo end pieces pressed in and first one is now glued! Another will be glued tomorrow, soon I can assemble CV's and put shafts in boat. https://cimg4.ibsrv.net/gimg/www.off...934f6e108e.jpg Nobody know how these hold up but if my calculations are right, glue joint have 40 times safety factor and tubes should hold two times the power. Transmash will be in good tune if it have so much power to explode carbon tube..... |
Don't you passivate stainless steel welds?

Omg! I’ve got a lot of reading to do. How much torque/hp is your engine going to make? Do you have an estimated top end? I know this has been covered already and I apologize for my laziness.
