What is the different specs between the old Detroit 12v71s and the Cummins inline 6 cylinder 6.7 liter replacements? What is the Hp and torque output of the engines and how much is the weight change between the two? How much slower are the Cummins re-power units going to push the boat at both cruise and top speed for when you need to make a dash top speed run for any reason? I expect your Cummins fuel consumption will be between 40% and 60% less than the Detroits at the same hull speed.

She didn't end up buying the hat. It was all talk in the end. Popeyes can definitely be hard on the body. We rarely have it but it's soooooo good when we do. The salvage yard was neat to see for sure. The only thing I saw thatbI wanted was a cnc converted Bridgeport milling machine that the owner of the yard had in the building collecting dust.

I liked the cool old delapilated “1051” tied up between the “New Pacific” and the sunken wreck at time stamp “14:55”. Now that boat has some character! I wonder if she is in as bad of shape as she looks to be. Looks like she needs a bit more than a scrub, scrape & paint.

@OnboardTangaroa

We didn't realize at the time but one of the propellers had some damage. We were also running the boat at 12-12.5 knots on the way down. With the combination of the bad prop and the higher boat speed we were burning 22 gallons per hour. This added up to about 1500 gallons of fuel burn to get her down from Alaska. After we had the prop fixed our fuel burn dropped to 16 gallons per hour at the same speeds.

@OnboardTangaroa I was interested in fuel savings. Or do you calculate that a gallon burned per hour at the same speed.
@OnboardTangaroa
@OnboardTangaroa 3 күн бұрын
For percentages I just took the data from both the detroit and cummins bsfc charts which list lbs/hp/hr for each engine at known rpm ranges. At our 1000RPM cruise area the Detroits are literally off the chart for low bsfc. Judging by the curve they would be sitting in the .48lb/hp/hr range. The Cummins with the new 3:1 gearboxes would be closer to the 1500 RPM range and show around .32lb/hp/hr. You can just determine the fuel burn difference from there.

It shouldn't adversely affect the handling. The weight was removed forward and the boat has always had a bit of a nose down push underway. We are expecting around a 34% reduction in fuel burn based on bsfc numbers of the Detroits vs the Cummins. Hoping to get the pitch right first try as well. Not too keen on having to come out of the water again any time soon.

Thanks! It's pretty wild imagining but it's all in the math. Tangaroa is a big boat but not a fast boat. If you don't need to go fast your power requirements drop exponentially. That being said, the Cummins 6.7 marine engines are rated to a max of 550HP and 1250 ft/lbs. The Detriots we had were rated at 458hp and 1200 ft/lbs. Eighty years of technological advances go a long way.

I was twitching watching Janis use an electric die grinder without safety glasses 🫣 Aluminum chips flying everywhere 😲 Somebody needs to give that girl a slap on the wrist or she might like a spanking better lol. Have a discussion about PPE. Yeah, I'm guilty about not using gloves or ear muffs. I sure don't screw around with eyes. Safety squints don't cut it. I've never tig welded before, we didn't do it in our shop or have one in our shop. With those engine mounts, I'd burn them in with 7018. I know some would say mig weld them. I don't trust wire feed welding. I want something to hold stick welding with 7018 it is. I know guys will argue that mig strong, yeah, I call bullsh*t. I know my welds hold the proof is in the pudding. The shaft couplers that come off the detroits talk about overkill 😂 I think you are going to notice a difference in quicker response when it comes to slow speed maneuvers. You won't be waiting for all that rotational mass to slow down or visa versa. You may miss it when cruising, the boat is prolly close to 1000lbs lighter maybe more.

Lol, when I watched the video before Janis posted my first comment was "You know someone is going to mention the lack of safety glasses". There may or may not have been a spanking later😁. Funny, I have been to the hospital twice to have small bits of metal removed from my eyes. Both times I was wearing safety glasses. Never had to go to the hospital when I forgot to wear safety glasses. Coincidence or. ???😂. I do love tig welding. It is so peaceful compared to slag flying everywhere. Its very similar to oxy/acetylene welding but cleaner. I have a fair bit of mig experience but absolutely no stick experience. Tig is pretty much my go to. It is just unfortunately very slow. The boat is actually 6000 lbs lighter without the Detroits. Will need to do some ballast work for sure.

Not really. The Detroits were the least powerful of all the 12v-71's. I think they were rated somewhere around 400HP . Of that 400 we have only ever demanded about 120HP. The new engines, while capable of 400HP will be derated to around 300HP. That still leaves enough for our original demands plus gobs extra for emergencies. Any additional power we had with the Detroits would have been completely unusable.

The bare aluminum is a preference for us but most of the fishing boats up here in the Pacific Northwest leave the hulls bare. It may not be as "attractive" as paint but you don't have any maintenance to protect the aluminum. It will form an oxide layer by itself which inhibits further corrosion.
