Torque roll

On my new boat, (350 DD) which side do I need to be wary of the torque roll affect? Gonna take it out this weekend for the first time and want to be prepared. Any other quick tips? I already know about "when in doubt gas it out"
 
NorthWest, something you will need to pay attention to now that you didn't before is backwash.
Because this boat is a lot heavier than your mini, when you're comin off plane the boat will settle in (my term ... there's probably a better one) a lot deeper, so if you get out of the power too fast you'll have a big hole in the water behind the transom.
That water can sink you if you if that hole fills up too fast.

When you're coming off plane, nice and easy until you get a feel for it. You'll get it. Have fun !
 
Should be the right side when you're sitting in the seat with a direct drive motor. Don't be giving it any left rudder when the torque's already trying to push that side down...that just helps it go down.

I always look to see if there's a shallow spot I can idle to & jump up on a plane there. Makes it a lot easier to get it up. :oops:

Mine gets up in its own length. Planes real quick. If I get a case of the DA and sink it, just leave me there Ill be fit to be tied anyway, won't be safe to be too close. LOL

Scotty :lol:
 
Bear, that's exacerly the way I think. If I've been that stupid, just stay away from me for a while. :lol: :lol:
 
yeah, what they said. :)

As a 350DD driver myself I can further warn you that when you are doing a LEFT turn at slow speed (not on plane) your right rear corner will want to go under.
Because there is another force that comes into play - centrifugal force as you go around a turn. Your top-heavy boat will want to lean to the right as you round a left turn at idle. Add the torque roll if you stab the gas a little and it'll push that corner of the boat right under the surface. 10 seconds later, you'll be on the bottom.

When you are maneuvering around, try to make right turns. Especially U-turns.... always to the right.

That right rear corner is your torque roll weak spot - to answer your question. Put your bilge pump there and leave it on if any doubt. It may not save you but it may slow down a nasty situation - maybe.

Having our large capacity bilge pump on that side saved us when wind, centrifugal force, and torque roll all worked together to push that corner of the boat under. I turn that sucker on and just leave it on when things are looking scary - like it was that day.
YEP - and the GAS IT OUT at the same time pushed us (as we were sinking) to shallow enough water that when it sank, the sides were still above the water... took over 10 minutes of bilge pumping to empty the boat. but we just drove away.

You'll do fine!!!
 
All great info fellas, exactly what I needed to hear. I would hate to go out there and make myself look really dumb in front of the wife on our maiden voyage (she is just looking for reasons to dislike this boat). But I got news for her the airboat ain't goin' nowhere, sink or no sink! Let the fun begin! :sign2:
