Torque tab or not...

[Toffen]

Hi all

Hope you all are well out there!

I will order a Verado 400R for my ol Phantom 25 in a couple of weeks. Currently I have a Verado 350 Sci with the standard 5,44 inch diameter HD case.

I will order the 400R with the Sportmaster lower unit. The question is if I should order one with cambered skeg or not. Some reccommend to mount the engine 1-1,5 inches off senter toward starboard and use a straight skeg. My ol Johnson GT 3.6 V8 was mounted this way back in the 80-ties. I have my Verado 350 Sci mounted dead center. When I had a Promax 300 with Tourqemaster gearcase mounted dead center it worked out fine.

I estimate the top speed to be approx 86-88 mph with the new engine running the proshaft even - 1 inch below the bottom.

What do you think?

Cheeers and thanks, Toffen

Chambered skeg in the middle. How would mounting motor off center affect propellar torque on the lower

Hi,

Mounting off center was typical way of doing it by offshore racers in the 80 and 90-ties. Maybe mounting towards starboard offset balance someway. Just as the driver and battery do being on starboard side.

Maybe off center could possibly be better. But I know for a fact a straight motor is more efficient than one that is twisted have see a bunch boats pick up few mph with puddy torque tabs. So middle or off center I would go chambered.

I believe you do not have the option of a straight skeg on the verado gearcase line. All of them that I have seen so far both RH and LH have the swept skeg.

With the motor off center your skeg runs straight. Thought of trying it on mine. I think its more commonly done on tunnels. Would love a jackplate with horizontal adjustment.

Definitely get the cambered skeg.

You may experiment with mounting the engine off-center, but unless someone has if figured out for your hull/engine combo, you are likely to end up with a bunch of holes in the transom before you have it figured out.

You just need two jackplates, one mounted sideways

Are you having a problem with how the boat runs now with the 350sci?

Mounted dead centre, and definitely get the cambered skeg!

Adding a torque tab to the trailing edge of my skeg did wonders for the handling of my boat, no more torque steer or wheel creep, and much smaller inputs needed on the wheel to stop any chine walking or leaning on exit. I can also jack the motor way above the keel (it loses water pressure long before any blowout, whereas before the tab it would blow out anywhere near level). One of, if not the best thing I've done with my set up!

Hi!

I have owned the 350 sci since 2011 and the engine itself has been flawless. However, the lower unit is big and in its first edition a little quirky to handle. The new HD case should be better. The maximum height is 2-2,5 inches below the bottom before it lifts the transom too much. As you know the HD case is huge. I have lots of water pressure.

The new Sportmaster has the same diameter, but runs without any probs much higher. The question ofcourse is if I can get hold of a prop which can accommodate it on my boat. The Sportmaster is longer and need to be run higher to offset its added drag. But it steer much better, and this itself should also help. I cut out a 8 inch notch on the transom this winter, so the boat runs not that flat anymore.

Hi!

I see some still recommends and use straight skeg with the sportmaster. One of them is running fine with this setup, another have problem with the steering. He needs to turn left to run straight. When the power steering get too much torque, the excess valve forces you to turn the steering wheel left to keep the engine straight. Which is a handful to do at high speeds.

Its always a question if the cambered skeg will steal speed as it is thicker than the straight, but I presume the positive effects of it outperforms the negative?

Torque tab. If for some reason you didnt like it you could grind it off but thats really unlikely.

Definitely not a fan of off center mounting an engine, there are way to many advancements in the high speed world now than were in the 80's . You will be more than happy with a cambered sporty
