Offset drive in narrow beam boat
 

Was told that if I offset the drive placement in my 7' beam boat it would help the boat stay more level under power. It kind of makes sense, but I would like some feedback. Boat is a 27 Excalibur, BBC and XR Bravo. The object is to try and keep the boat level without dragging a trimtab all the time.

Cheers,

Andy

Joe Shaldenbrad of Sunsation Boats offset the engine in his 24 ft. Rockets and Aggressors about 3/4 inch to help compensate for propeller torque.

I don't think there is an offset on my boat. I never measured or heard anybody mention it. The only time my boat leans to the left is at FULL DOWN trim. When I come on plane it leans but as soon as I give it a little trim it levels right out.

Since it is a bravo, try running a left hand prop instead. It counters the torque. I have done it before, and have seen Fountains the same way.

As long as your engine is Std. rotation BBC a right hand prop turns the opposite of the motor, not a left hand.

lefty props do in fact oppose the engine rotational torqueon single engine application's. i have tested this on many small vee's with slight to very good results depending on h.p/ torque. you may also want to play with # of blades and diameter.

Wouldn't running a left handed prop just make the boat torque roll in the opposite direction? :confused:

No Boat; YES

Center the drive and remount batteries or other things to make the boat run more level.

Thanks for the comments. I'm leaning to the 3/4 offset. Will have to look into that a little more before I cut the hole.

Thanks,

Andy
