Amazing work very impressive. keep up the great work

Like a few here no doubt, I read every new post and find it all fascinating. If only I understood every post!

The OP’s expertise is amazing, it’s great to see thing coming together. Huge thanks for taking the time to post the progress.

RR.

It's hard to even know what to say when it's so over my head! Absolutely amazing progress looking forward to seeing it in the water this summer!

Thank you for sharing

Looking forward to see the the beast in the water.
Please keep the updates coming!

Please keep posting your progress, love the innovation.

as others said...KEEP POSTING! We're all cheering you along just not posting so we don't clog up this awesome thread!

Thank you of support!
Maybe I should write this to end, whatever it will be.

It suprice me how much hydraulic hose is in basic powerboat! Huge amount of fittings and hose. Here in picture is only inside boat hoses. Outside hoses will be stainless fittings, kevlar braided.

R1/8 ends pressed.

Next extension boxes, if I ever have to make them again, I will put more space between welded thread inserts. They barely fit.

Three bilge pumps, two 1100gal/h and one small rubber impeller pump. All taken from separate fuses, automatic big pumps have continous power that doesn't cut from main switch and both have own fuse, if another fail, another keep pumping. Engine room front bulkhead, under tanks draining holes are now only 6mm each and front bilge pump under cabin stairs is also 1100gal/h so if Transmash explodes and piece of connecting rod goes through the boat bottom, boat should float as long as batteries have power for pumps. LiFePo4 batteries have 5.8kW energy stored when full at 90% discharge, pumps draw 2.5A/24V each so 7.5A total. 28h running time for bilge pumps, in theory. Should be enough to get near shore, somewhere shallow place.

Third rubber impeller pump draw water inside of rear drain so bilge can be pumped total dry. That pump have three way valve, you can choose pumping overboard or quick connect fitting to longer hose that can go to some bucket outside of boat. Oil, coolant, or fuel leak can be washed and not pumped to our one of world cleanest lakes. I can drink water or make coffee almost everywhere on lakes.

Heater assembly is near completed, some exhaust fasteners and heat shielding missing. Other diesel heater heat cabin and other heat cockpit, it's nice to use boat later in autumn with full covers that are warm, boat dries up much quicker too after rain.

Own design engine mounts, aluminium with steel ball joint inside which allows engine package tilting and small longitunal adjust, but they are still solid, no rubber. This way I can line up drive shafts after test drive so CV joints get as small angle as possible in that trim setup which boat runs best. Hard to explain but rear CV joints turn when steering or trim is used.

Carbon drive end pieces came from splining and heat threading. They are made from billet 34CrNiMo6 steel and will be glued to carbon tubes after I measure correct length when engine is first dropped in. Glue is Loctite 9466 epoxy glue, 32N/mm2 shear strenght, make about 40 times safety factor with this much glue surface area. BUT it's just in 20C temperature, if CV joint make too much heat and warm steel part up, safety factor will go down. That is reason I put real time 4 channel CV joint temperature gauge with warnings in dash:cool-smiley-011: It uses industrial infrared touchless 4-20mA sensors. Was this enough complicated for you?

No rubber for motor mounts, even if just for vibration damping

Have been around different machines that did not have any rubber in mounts and most develop a sound harmonic kind of noise which can travel thru entire machine, and in this case maybe the hull

First drivetrain i've heard of with infrared temp sensors on joints -- very nice touch... Wish i had that when i spit a u joint cross out of my driveshaft and it took out the transmission:cool:
Looking good!

You would think the same thing about an aircraft carrier, but the Russkie carrier could be seen from miles away from its massive exhaust plume.
