Cambered skeg or not...
 
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

Hi Toffen, May need help here, I know of swept skeg (for single eng application) and straight skeg for multi eng. but not cambered? .please define.

on O/Bs
yes swept back skeg with a torque tab on it is common for single motors
the wider skeg give better straight line control
and with the torque tab on it u don't have to offset the motor
as in a single u want the skeg centered to the hull for best handling results
offsetting is very old tech but helped back them days
especially like the old v-8s they had a small skeg to strart with
and yes straight skegs with no torque tabs are twin set ups
with 2 skegs don't need as much skeg width
and opposing rotation props takes out the steering torque

On a single engine cat is there any advantage to running a torque tab?
Imco Bravo type drive. propshaft is 2 inches above the bottom.
