Eliminator 19' Daytona set up
I'm helping a buddy of mine set up a Eliminator Daytona 19' w/merc 2.5 drag. Any body have any ideas on set back, engine height and what a good all around prop would be to run? Any info would be great, thanks!

Eliminator
From what I have seen the tunnels run best with a Cleaver prop becase of the natural bow lift of the air packing under it. So you have to get the back up and the Cleavers create stern lift. I even use one on my boat even though it is a V-pad.

19' daytona
I was told the boat weighs 600lbs, but I haven't weighed it. It's a 99 powerhead w/26cc heads, 15" mid, stock sportmaster, 1:87 ratio. Not 100% sure on the gears either but that's what I was told. Thanks again for the info!

600lbs
My 15' Viper weighs 575lbs empty and it is laid as a fairly light weight hull.

600lbs must have been before rigging and interior or that is one flyweight daytona. I would try about 16-18" of setback. Something like a detwiler 6" hydraulic on a good fixed 10-12" plate that is cross braced and has a water deflector so it doesn't act like a scoop. I like the Yamaha props for these rigs but ETs and Tritons work pretty good too. Be careful wear a helmut and a lifeline for testing this boat like a RC Riot or a Scorpion only runs fast pretty bow up and is not afraid to become an airplane.

HJow about an '86 21' Daytona ?
With a 235, how much setback? Now (2) 235s? How much setback? I currently have 13" total. 7" of static bracket and a 6" Bob's hydraulic. I was contemplating another identical setback for twins, and 2 manual jacks.

600 pound 19 Daytona is a little lighter than average, but I have seen them under 400. * inches back prop shaft even and a lightning et assuming its a standard bottom.

I have an '82 19 ft. Daytona that I refurbished. Supposedly it was a 500 lb. bare hull, but I added a lot of interior weight, including a gas tank under the bow, and heavy seating for 4. I had a problem with a cleaver cause I couldn't get the bow up, but with a 34" cleaver and 2 miles to run it, I am doing 96 mph on GPS.
Everyone here runs 1/4 mile, so I added 15" of set back and ordered a 4 blade drag chopper from Tim Hackney. Prop is 3/4" above center pod. Boat runs 86.5 in the 1/4 with good bow lift. These boats are very sensitive to weight, so the lighter you can keep it, the better off you will be.
I added a lot of weight because I wanted a 4 seater lake boat. If you keep it light, be very careful with the trim. These boats WILL blow over.
Good luck and be safe.Wayne Tarrant

That drag chopper you put on, what pitch is it and what kind of speed are you getting? Thanks.

I am running a 5" setback bracket with a additional 6" jackplate. I believe that is too much setback, even with a full interior. I run a 26p small ear Merc chopper. I have run it up to 8000 rpm at 96.8 mph with a lot more throttle before it got real light. I am only running a 2.5 245hp carb motor with shaved heads. I think a 28 et or drag might be a better prop. I would like to try a 28 or 30 cleaver to see what that is like.

A's A,
The prop is a 28 pitch. 86.5 in 1/4 and 88 top speed on a good day, but I am only turning about 6550 rpm's. Keeping my motor dependable, so far.Wayne Tarrant

19' Daytona
I like that boat. Mine is somewhat of a copy but is had no center pod. That hurts holeshot and complicates the setup a bit, but it sure helps rough water handling. It's an '82 19' Sterling Carrera.
I have found that generally my motor needs to be much higher than a similar boat with a center pod. 3-4" higher! This complicates things from a dead stop. Getting on plane with the motor that far above the boat's fulcrum point is impossible. The solution is a hydraulic plate with a lot of range.
My boat has maybe 5" total setback (including the step behind the pads) and doesn't need an inch more. It flys very easily. So easy, that cleavers are all I would reccomend. I think when the boat starts to get into the high 80s-90s It will be faster with hardly any trim as it will start to pack air much better. Under 75-80 and I can trim all I want, it doesn't help but looks cool
