That case looks like it's been welded there.

It does look that way.

Your always trying stuff outside the box, why end it at a centred motor..

I am just starting coffee 1 this morning, but.
Moving the engine off center may well help with a boats dynamics, that is a good thing.
But it does nothing for the dynamics that are trying to wrench the wheel from you hands.... Correct?

One way to improve the life of the skew is to grind the torque tab away and to make the profile of the Skeg asymmetric like an airplane wing with the flat side on starboard and more curved on port side. This also usually gives a few extra miles.

Lightning cases come with a profiled skeg and we still need a tab with big wheels

No IT does not, but it makes the boat go straiter and faster.
One may use a rubber rope to counteract the steering torque. Makes the low speed driving a little strange but works good at hi speed.

I have heard of this trick before, do you have any pictures of setting it up? Also heard a person using it on seastar system.

Thanks

The bungee setup is popular with the guys that race inflatables with tiller steer motors. BTW, check out some of their racing videos, those guys are crazy!!!

Are you the guy who created the Hydrostep hull?

I have been playin with my SLT (race inflatable) and I am lookin into building a bungee steering assist system . Robby 321 had posted some pics of one system a couple of months ago ...... I'll try to find them. Gary

Anyone have any Yamaha jets they would sell? Ill have to drill them so size doesnt matter.

This is what I need.

Kind of curious. My mixture went rich after raising the ex ports. Figure I lost some efficiency? Compression dropped about 5 pounds but its pretty fat now. Im guessing Ill have to drop 2-3 drill sizes.
