Poseidon new Verado lower unit
Hi!
There will be a new 3rd generation lower unit for Verado 6 cylinder engines, especially for 350 sci this is very exiting as the 2nd generation version is slower than the 1st edition.
The start of production for the Poseidon-equipped Verado models is as follows:
Standard Poseidon (black finish, 1.85:1 ratio, 1" propshaft): September
26, 2010
Heavy Duty Poseidon (silver finish, 1.75:1 ratio, 1.25" propshaft):
November 26, 2010
Verado 225 -300 HP: October 2010
Verado 350: December 2010
According to the note my dealer received, a multi-engine boat must run either all Verado (current) gearcases or all Poseidon gearcases, but not a combination thereof.
Have anyone of you seen this new Poseidon lower unit and do you know if its faster than the 2nd generation? The 1st generation was standard V6 size and could be rised up a bit. The 2nd gearcase is bigger and do not like to be jacked up (although I am sure you could plug some waterintakes and get it up). I wonder if the new 3rd generation has adressed this.

Hi!
I am uncertain if the new Poseidon gearcase have waterintakes in front such as Torquemaster. I do not think it will have low water intakes such as the Sportmaster.
Check out www.thehulltruth.com about conversion of the Sportmaster to fit the 350 sci. If I am correct the bolt pattern is not the same, nor the splineshaft.
The fastest lower unit per date is current 300 Verado housing. Its smaller than the 2generation 350 sci gearcase, but prudent to failure. I hope the new Poseidon will be faster than the 2nd generation. Maybe someone out there have some pictures? And info?

Hi!
Have anyone of you received any info about the new gearcase yet?
Just got info that www.gtrraceboats.com from Australia deliver reworked Torquemaster and Sportmaster units for 350 sci. Good news.
Cheeers and thanks! Toffen

Hi!
Here are update on the new LU for 350 sci. Looks like it just as before, but that all Verado models from 225-300 can choose between the HD LU and a smaller standard LU. That means that 350 sci still has a disantvantage with the big LU with regards to drag. Why put a slower LU on a Merc Racing product, as this is the only LU possible to buy. In the text below it states that the bigger 5,4inch LU gives more lift. Transom lift or bowlift is not clearified here. Any ideas?

L6 Verado Product FAQ’s
1. What do the 4.8-inch and the 5.44-inch designators mean?
The 4.8-inch and 5.44-inch designators in the model description refer to the diameter (size) of the gearcase torpedo. The 4.8-inch variant is the standard (current) size gearcase, while the new 5.44-inch variant is the new, larger gearcase.
2. Why did Mercury introduce the larger 5.44-inch gearcase for L6 Verado models?
The 5.44-inch gearcase is a larger, more robust version of the 4.8-inch gearcase with strengthened internal components. It was designed primarily for markets which in recent years have been trending toward larger, heavier boats that venture farther offshore and experience rougher sea conditions.
3. Which boats will benefit from the larger 5.44-inch gearcase?
Larger, heavier boats, non-planing hulls, or heavy-use commercial/patrol boat applications in twin-, triple-, or quad-engine configurations will benefit the most from the 5.44-inch gearcase.
In single-engine models, these boats are typically 23-foot or larger boats weighing 5,000 pounds or more fully loaded. These boats will benefit significantly from the added lift supplied by the new 5.44-inch gearcase.
4. Is Mercury still offering the current, 4.8-inch gearcase on Verado?
Yes, the current 4.8-inch gearcase is available on select L6 Verado models, including 225 L and XL variants and the new 250 and 300 Pro FourStrokes.
5. Why should I buy a Verado with the 4.8-inch gearcase when I can get a Verado with a 5.44inch gearcase?
The standard 4.8-inch Verado gearcase is the best choice for single-engine boat applications that exceed 55 mph (including bass, freshwater multispecies, inshore flats and bay, and tri-toon boats). It is approximately 13-pounds lighter than the larger 5.44-inch gearcase and has a smaller hydrodynamic profile, that ensures top performance on these boat types.
6. What’s the difference between the 300 hp Verados with the 5.44-inch 1.85 vs. the 5.44-inch 1.75 HD gearcase?
The differences between the 5.44-inch, 1.85 gearcase and the 5.44-inch, 1.75 HD gearcase are the gear ratio (1.75 vs. 1.85) and propshaft diameter (the HD gearcase features a 1.25-inch diameter propshaft, 25 percent larger than the standard 1-inch shaft on the 1.85 gearcase). As a result of the larger 1.25-inch propshaft, the HD gearcase requires the use of Mercury Racing’s 1.25-inch solid propeller hub kit (the HD gearcase is not compatible with the Flo Torq II shock-absorbing hub system).
7. Which 250 or 300 hp Verado should I buy?
If you’re running a single-engine boat that goes over 55 mph, such as a bass boat, a freshwater multi-species boat, flats/bay boat, or a pontoon boat, we recommend you go with the new 250 or 300 Verado Pro with the standard 4.8-inch gearcase.
If you’re running a larger, heavier single-engine boat with a top speed of less than 55 mph, or any multi-engine (dual, triple, or quad) boat, you’ll want to go with the 5.44-inch, 1.85 model. This larger gearcase will provide the added robustness and lift that these increasingly larger boats require. In addition, it will provide the shock-absorbing protection of the Flo Torq II hub system.
If you’re the type of offshore operator who continuously finds yourself in very rough seas, or if you’re a more aggressive boat driver who finds your propellers are frequently ventilating (the propellers are coming in and out of the water rapidly, creating significant load / unload on the engine’s drive train), you will want the 300 hp Mercury Verado with the silver 5.44-inch, 1.75 HD gearcase. The 5.44-inch, 1.75 HD gearcase provides a larger propeller shaft and the solid hub system that is more suited for this type of environment. It is important to note that this gearcase option requires the use of Mercury Racing’s 1.25-inch solid propeller hub kit (the HD gearcase is not compatible with the Flo Torq II shock-absorbing hub system).
8. Why are the 225 L and XL 4.8-inch models unchanged in the model offering? Why isn’t there a 225 Pro FourStroke
The 225 hp Verado with the 4.8-inch gearcase does not meet the performance standards required of the new Pro FourStroke, but we feel it is important to provide our customers with the choice of the smaller, lighter and faster 4.8-inch gearcase option.
9. Is there a performance difference between the 300 Pro FourStroke and the 300 Verado with the larger gearcase?
The actual power output of the 300 hp Verado is the same regardless of which gearcase is used. However, it is important to note that the 5.44-inch gearcase is significantly larger than the 4.8-inch gearcase. On some boats this will be advantageous because the added weight and lift of this gearcase will help increase boat speed. On smaller, lighter boats, the 4.8-inch gearcase will likely deliver higher top speeds due to lower hydrodynamic drag characteristics. Mercury recommends the Pro FourStroke variants for all single-engine boats that travel faster than 55 mph, including bass, multi-species, flats/bay, and tri-toons, for maximum performance.
10. Are there any changes to the 350 SCi Verado gearcase?
The 350 SCi has been using a 5.44-inch gearcase with a 1.75 ratio since it first entered production. The new 5.44-inch, 1.75 HD gearcase will be used on all 350 SCi Verados going forward; however, it is very similar in appearance to the original silver 350 gearcase and its performance will be virtually identical.
11. I have a boat with duals, triples, or quads. If I need a gearcase replacement, is it possible to just replace one gearcase or do I need to replace the gearcase on each engine?
In the event you need to replace a 4.8-inch Verado gearcase with a new 5.44-inch gearcase, you can work with your Mercury authorized dealer. While the gearcases are visibly different, your dealer can work with you on upgrade options. It may not be necessary to replace all the gearcases.
12. Will there be propping changes I need to know about between my current Verado gearcase and the larger, 5.44-inch gearcase?
If you upgrade from the 4.8-inch, 1.75 gearcase to the 5.44-inch, 1.85 gearcase, you may have to re-prop your boat (most likely by sizing up one pitch) due to the gear ratio change. This will be entirely dependent on your individual boat and how it is set up. If you are upgrading from the 4.8-inch 1.75 gearcase to the 5.44-inch, 1.75 HD gearcase you will most likely be able to use the same propellers; however, you will need to use the 1.25-inch solid hub kit from Mercury Racing. Of utmost importance is ensuring that your Verados are running within the proper full-throttle operating range (5800-6400 rpm) with normal fuel and boat loads while providing the best combination of acceleration, top speed, and fuel economy depending on your individual needs. In the event you do need to re-prop, your authorized Mercury dealer can help you select the best propeller for your boat. You can also use Mercury Marine’s virtual propeller selector tool at http://www.mercurymarine.com/propellers/prop-selector/#.
13. Will I require different propellers for the 4.8-inch and 5.4-inch gearcase?
Once you have selected the appropriate propeller style and pitch for your boat application, any of our standard V-6 / I-6 Mercury Marine propellers with a 4.75-inch prop hub diameter may be used on either the 4.8-inch or 5.4-inch Verado gearcase.
It is important to note that the 5.4-inch 1.75 HD gearcase option requires the use of Mercury Racing’s 1.25-inch solid propeller hub kit (the HD gearcase is not compatible with the Flo Torq II shock absorbing hub system).
