Does anybody have any knowledge or data on how weight reflects e.t & mph on your average river racer? Lets say a passenger of 150lbs vs no passenger I know theres some varibals on this question, however im trying to get a baseline. thanks,

I've always heard .10 for every 100 pounds, but don't know that.

me alone (220lbs), 2 full tanks of gas - 71.8
me, 2 full tanks, 135lb passenger - 68.3
me, 2 semi full tanks, 275lb passenger - 66.9

Steve,
The ET should increase with more weight not the opposite. :)

I compensated with diverter angle and a manually adjustable loader. :p

In my Rogers v-bottom, I weighed the coctail seats (65 pounds each) and trading them out at the track for a single fiberglass bucket seat was worth 2 tenths of a second off the ET. Removing the false floor (which was a waterlogged and heavy 3/4-inch thick plywood board) was good for another tenth and a half.
Weight is crucial. Put your boat on a diet and see what happens. I dont remember what the mph increases were though.

Did you take in account the added resistance on the bow eye bearings?

[Cs19]

Ive heard 60 lbs. is worth a .10 on a good boat.
In my opinion, if you shave enough weight you may be dealing with a tottally different boat.

[Cas]

which leads back to another thread. Will removing weight change the center of gravity? and how much?
William,
I drilled 2- 3/4" holes on either side of the bow eye to let air pass through instead of around the hull. It, in essence, makes the hull like a flute. Different wind conditions give a different tune as the air passes through the holes.

[mares98]

60 lbs sounds reasonable for .10 what about losing the place diverter? Any significant advantages or disavantages? Seems like it would create drag and more weight in a race only environment.

[Cs19]

Your not using the diverter at the races?

[mares98]

Yes but my hands were full at the starting rope in effort to or cut a lucky r.t. No neutral last time out.had the diverter sorta locked at 4 degrees, need to drill holes in my reverse bucket.

[mares98]

Still what performance gains with a place diverter at W.O.T This is a learning curve so please be patient.

[Cs19]

Talk to the guys that race gullwings and take notes, there is a reason most of them have diverters.

[Cs19]

Brian, just curious.. Are you running a manual or hyd. Place diverter?

[mares98]

Im running a manual. If I cant get this set up to e.t & mph in the next couple of months The blown combo will be history.

If your on the river and losing the race---kick out the passenger[s], you won't believe how much difference it makes! Plus there's more beer for the driver! Budlight

Ya I agree. Get that new engine Ive heard about in there, that should do it. :)
You should get the conversion kit that takes your manual diverter to a hydraulic unit...Simply using the diverter to get the boat to take a better set could be worth some et. Trying to do this with a manual unit on a race boat isnt the best way to do it.

I already kicked her seat out. She wuoldnt talk to me all day when she discovered that one.

The new engine will be ready in a hot minute if this season fails me.Seriously I wish I had a new mill, unfortunately I may be in limbo when that happens.
