200HP Vs 220HP in an R27?

[Toki]

Something I've realized recently; my 2016 R27 has the 220 HP Volvo D3. I see other R27's out there with 200 HP D3s. This spurs on a couple questions:

Did R27s switch from 200 HP to 220 HP at one point, or was the 220 HP always a factory option/upgrade?

Mechanically, what's the difference between the 200 and 220?

Thanks

Mechanically there is nothing different. Same Turbo, same exhaust, same injectors, same everything, except software. Programing !! My honest opinion is the biggest difference is longevity. A 150 hp D3 run hard is going to last longer then a 200hp run hard, A 200hp is going to last longer than a 220hp. Bottom line on diesels longevity is how much fuel has it burned. Hrs are not as important has fuel consumption. 220 hp burns around 12gph to make 220hp. A 200 hp burns close to 11gph to make 200hp, a 150hp burns close to 8 gph to make 150hp. The engine mechanically are all the same which one last the longest if run hard? I have the 220hp it is a little power house. I run it at 70% load most of the time burning 8.3 gph 3380 rpm. That is more then the 150hp can burn and more Hp than it can make. They are the same engine.

Thanks Brian, that makes good sense.

I suppose another way to couch this is as follows: at, say, 3000 RPM, both the 200 HP and the 220 HP will make the same boat speed, same fuel burn, and same wear & tear on the engine. The difference is, the 220 HP will give me a little more RPM and boat speed at the very top end, but at the cost of higher fuel burn and more engine wear & tear. Sound about right?

Did the switch from 200 HP to 220 HP affect all R27s made after a certain date or hull#? Or has the standard always been 200 HP, and the 220 HP was an option/upgrade?

The best way to look at the numbers use fuel burn as your comparison. My opinion is that fuel burn is a better gauge of HP and longevity than RPM and Hrs. Two identical boats correctly propped one running 3000rpm 220hp and the other running 3000rpm 200hp will not make the same speed. The key component (correctly propped)

Engine Hrs compared to gallons of fuel used. Two engines mechanically identical. Both have 1000hrs. One engine ran most of that time at 3400rpm 70% load 8.5 gph. The second engine ran most of the time at 2250 rpm 25% load burning 2.5 gph. Which one has more wear both have run 1000hrs ? 8500gallons of fuel or 2500gallons of fuel. Another thought on this is same two engines get the oil changed at 100hr intervals. Both owners send oil samples in. The oil sample form asks how many engine hours. The two owners compare results. The wear particles will be higher on the 8.5 gph engine than the 2.5gph engine.

Volvo makes these engines to be used in a wide variety of boats. Honestly a 220 hp 2.4l D3 is more suited for a high speed planing hull then it is for a semi-displacement hull. A fast planing hull will jump out of the water quick with full throttle acceleration and then be throttled back to around 2800rpm range for a fast cruise. Probably last forever. A 150 hp D3 is more suited for a semi-displacement boat plenty of low end torque and capable of pushing the hull at 10 to 12 kts which is a good speed for a semi-displacement hull. Boat manufactures want to show the best of both worlds great fuel economy at trawler speeds and fast high speed cruise. The problem with that is a semi displacement hull is hard to push through the water fast. It takes a lot of power. Ranger Tugs and Cutwaters are fast semi displacement boats not because of fast efficient hull design but because of HP. The 220 hp D3 in the fast planing hull is running most of its life at 50% load or less to cruise fast. The 220 hp D3 in a Ranger or Cutwater is running 80% load or higher to cruise fast. I'm not saying I wish that Fluid Motion put a 150 hp in my Cutwater. I'm saying I wish it had a D4 300hp in it so I could cruise fast but not use 80% load plus of the available HP.

I also have a 2016 R27 with the 220 HP. I asked about this when I purchased the boat new. Apparently, when the Cutwater 26 was discontinued, there were a half dozen 220’s remaining and they were used in a small number of 2016 Rangers. I guess a few of us have something quite rare.

I believe RT switched to the 220 during the last year of production. I heard from another R27 D3-220 owner that RT had commitments with Volvo for a few more 220’s and chose to use them in the last of the R27’s. I was told only 7 of this configuration were made.

Thanks Curt, but I'm not sure about that. Mine's a 2016, and 2017 was the last year of production for the inboard R27. Also, poking around Yachtworld looking at the specs for 2016 and 2017 R27s for sale, I see 200 HP listed for both years.

The answers to this are no big deal, but if it's true that mine is one of only 7 made with the 220 HP, that's an interesting bit of trivia to know about my boat!
