  1. Marine Engineer Grade 2 here,,, make sure you have sacrificial anodes on both raw water and engine coolant sides, otherwise electrolysis will corrode the metals quite quickly, especially the stainless and aluminium as they are not friends especially when there is a slight current leak. only has to be .1 of a volt ,, there is always a tiny bit of current leak with boats and this will also accelerate elecrolysis, Anodes ARE a must have Chris

  2. Lol. Just a couple of bros trying to get 1 of 2 LSX boat engine for an Italian yacht to run, while a fully custom, off-road LAMBORGHINI HURACAN casually chills in the background. Only at BisforBuild ladies and gentlemen.

  3. Boats…anything with boats has so many unexpected, and time-consuming tasks…interesting thought for me, though, is why have such expensive engines without upgrading your engine heat exchangers? Yea, they're expensive, but so are the motors they protect. Fix the problem before it becomes one

  4. The engine oil cooler is WAY undersized. It should be replaced with a cooler sized for at least 750 hp. Preferably more. I have used this unit in the following link with good results. It's a full flow by pass unit with built in thermostat.https://www.mrcool.us/mrc-cph-700.html If you can't swing the expense, PLEASE install a oil temp sender in the pan!!! Keep a close eye on oil temps during sea trial. The engine cooler in your vid is sized for a 260 hp engine.
    There are other issues I see, but the oil cooler is a BIG problem.

  5. So I’ve been watching your channel for a while now, I’m a marine mechanic and specialize in re-powers on boats in the 40-90ft range. Please make sure that these motors make rated RPMS. If the motors on a stand make 6000 they should make that in the boat as well (that is running the boat on the first sea trial). Reason being is because you can easily overload those motors. One downfall I considered and was slightly disappointed you did not go with a diesel, simply because in order to make RPMS in your boat, you will have to turn a very small prop. Making maneuverability much more difficult just my take on the plan. I have done give or take a 100 of these jobs. Just my personal opinion
