Okay, here's my 21' Daytona DCB. Great boat, love it. Had it for a year and a half. Motor went kaboom. 51 hours on a Race 2.5EFI. 4 inch crack in the top of the block. I was running a 24 mazzco prop. Jack plate, set back, etc. It would run just shy of 70mph gps with two people and the top up. Doesn't that seem slow for this set up?




I have had so many discussions about what to do with this boat. It's a 90's boat that I have considered taking back to Dave @ DCB and having everything redone (paint(not gelcoat), interior, motor). That would be pushing 40-50k with a 300XS. Ouch!

We have decided to put a new 300XS on it and save the interior and gelcoat for a few years down the road (it still looks good). Here's my question.

Jack plate or not? I have one now, but don't think it will hold the 300.

What gear case? I don't pull any skiers or wakeboarders with it. Just run up and down the southern colorado river north of yuma. Would like to spank most jet boats when desired.

How fast should this thing go with a 300XS? People have told me that it would easily be in th 90s. That would be nice.

What kind of hydraulic steering should I go with? It is manual right now and a hand ful. The wife doesn't drive it. To put it in perspective, she used to drive and trailer our old miller jet boat, this thing is a monster without hydraulic.

Anyway, the boat is great and don't want to cut any corners, but do everything just right considering how much the repower cost.

Your opinions are appreciated.

How much does it weigh?

How high was the prop?

Should have been faster than that, at least 90 with a good running 2.5 EFI. These type of boats typically run 100+ with a 300XS with a sportmaster. You do want hydraulic steering, preferably on a wing plate (to have a larger bolt in shear).

Our 21 Daytona runs 90 with a V8 evinrude, and that is with the nosecone over an inch below the pad (no jackplate, just a setback). I think just lifting the engine another inch is probably worth 5mph but we don't have a way to do it right now.

I'm not sure what the weight of the boat is. I'm sure someone with this boat knows.

As far as the height of the engine, I would have to take a look at the motor in relation to the bottom of the hull. I only know the indicator up front as a reference, but those numbers are useless without knowing the difference between the engine and the bottom of the hull.

I know the 300xs are supposed to do 90+, but I didn't think the 2.5 had enough beans.

I will take some pics of the motor height and reference the gauge up front. I'm out at the river now with our Jet Ski. I'll have pictures this weekend.

Wildman, if you want to pm me with what you have in mind for a 300xs, I would entertain it. I'm out on the west coast remember.

Thanks, Steven

Steven,

I also have a 21 foot Daytona and have been trying to figure out the ideal setup. Right now I have a Big Johnson 300HP V8 with a jackplate. It has a 3 blade mirage prop and I am only getting 80MPH with 1/2 tank of gas. I was told by a previous owner that they were able to see 100MPH all day long. Not sure what to try.

I sold a new 300xs to a guy with a 21 Eliminator in Lake Havasu. He's has his up to 102 mph.

Yeah, that is a great motor! Lot's of power, light, and reliable. I saw a guy on hear yesterday selling a Trick Cat w/ 300HP MERC locally. Seems like a great boat. They are made up in Lake Cumberland. I told him it looked like a cross between a Skater and Daytona. He said he get's 105mph w/ that setup. My GT300 V8 is a great motor, but heavy compared to the MERC. I was going to maybe beef it up over the offseason w/ bigger pistons etc. If I am in the market for a MERC, I will definitly give you a call!

Yep, I'd love to get one(300XS), but coming up with 20k to make it work is a bit much right now. Probably going to just redo my 2.5 260.

Hi I have a 1993 Eliminator Daytona 21' was originally rigged like yours but with twin 2.5 offshores.colors and layout identical where your dark blue was turqois same stripes top everythig.I redone the colors interior engines gauges.When i bought it it had only 1 engine on it the previous owner sold the other. I put 2 225 johnsons on it slightly warmed over so far with just breakin time on them 80mph was very easy to reach but lost a pinion gear on the counter rotator so i have to rebuild it now.I have owned 3 now all of them went over 90 mph easily.just have to play with set up.With that 2.5 you should be mid 90's easily.

I don't think the motor was ever high enough out of the water. I was only seeing 65-70mph gps. Love the sound of these motors, though. I've seen the exact paint scheme your talking about down at the river.

Gotta have hydraulic steering, new throttle assembly (foot throttle), etc. I figured 20k before I was done.

I let the guy before me do all the work, powder coated trailer with leds, livorsi, stereo, subs, hyd lift, foot throttle,etc. It was much cheaper that way, until the motor went bye,bye.

I got a good weight for my '86 21' Daytona w/Yamaha 220 V6 Special. Trailer and fully rigged boat with about 10 gallons of fuel was 2490 lbs. Trailer empty was 1090 lbs, so 1400 lbs w/ 19 Gallons fuel. P.O. claimed 83 mph...

I have a 1991 21' liberator with a '93 260 on it and ive only had it up to 5700 rpm and that was good enough for 72 mph on GPS. I have some issue where I can't get it above 5700 RPM right now, but 90 should be easy wwith a 2.5. My boat is Kevlar layup so I am not sure how much of a weight difference that makes.

Carhartt,
Mine is Kevlar also, but running a 225 Yamie right now. I've seen 5900+, and upper 70's, and am about 3" below keel swinging a 26" over hub cleaver(?). Getting LWP and a new nose cone this winter and raising it up a couple of inches.

Also sent you a PM>>> ;)

90+ should be obtanable with a 2.5 260 or 280....70mph with a 24p two people in the boat and the top up isnt bad...running a 30p mazco re3 with one person (these boats are weight sensative) and the top down...(top is going to add a ton of wind resistance when its up)...i think that you see a drastic increase in speed!...running with a load in the boat...more than one passanger...you may want to go with a 28 mazco re3...good luck..let us know how it works out :cheers:

Listen to Wildman! Purchase a 300XS! Awesome!!!<O:p</O:p
<O:p</O:p


I am the one with the 21' Daytona in which I purchased my 300XS from Wildman.

The 300xs is a different beast than the 2.5 and thus a totally different set-up especially with the Sportmaster 1.62 gear case. <O:p</O:p

Hi there,

I have a 1985 19ft Eliminator that I have just re-done. With a 225 Pro XS I running in the 84 m/hour range at the moment. I have a 7 inch set back and a 6 inch manual jack plate, totalling 13inches back. Running a 28p Trophy plus Lab finish at 5750-5800 Rpm.

I must add that I cut the centre hull and made the boat run on the outers, this was due to problems turning as we race circuit races with them.

The boat is also the TALON copy I think as the original paint work had this on the side, four people pick up the empty boat with ease.

My buddy has the same boat with a 300xs Opti that run in the 92m/hour range, before we removed all the timber re-enforcing some one added on top of the tunnels.

Check them out at www.sahardbottom.co.za (http://www.sahardbottom.co.za) boats #2 and #100

That boat of yours should be moving.......

Cheers :cheers:

Hello Again,<O:p</O:p
<O:p</O:p

The key for running a 300xs with the Sportmaster 1.62 on a 21' Daytona is about 12-15 inches of set-back--depending on the weight of the boat and Transom height--1.5"-1.75" above the middle pad. I have run 103.4 mph at Lake Havasu,<ST1:p 80 degree weather, and was spinning a Mercury Pro-Et 30" Prop at 6,200 rpm. I know the 300xs produces maximum horsepower at about 5,900 rpm and thus my next prop I will try a 32" pitch Cleaver Prop, 15" diameter, since the 300xs has lots of torque.

<O:p</O:pThe boat is a Kevlar lay-up and it was the second 21' Daytona from Eliminator out of the mold for an outboard. My dad purchased the boat in 1982 from Steve Buckalew who raced it in the MVP class in the Parker Enduro in 1980 and 1981. Al Stoker probably remembers Steve and the name of the boat was "Quick Screw." Just thought I add a little history.
<O:p</O:p

I restored the boat from my father and the 300xs is a great motor; moreover, my dad purchased Steve's second 21 Daytona and is almost finished rigging a new 300xs.
<O:p</O:p


One last note—someone from a previous thread mentioned that the Daytona’s are not fast-well—the Daytona is not a Stoker or a STV for top-speed; however, give Eliminator a little credit for being the first to mount an outboard on a modified tunnel and race their product. Remember the Eliminator Daytona was designed for a Jet boat—not an outboard—and many current ¼ mile jet boats racers continue to choose a 19’ Eliminator Daytona for their boat of choice.<O:p</O:p
<O:p</O:p

I hope this set-up helps—One should be able to run over 100 mph in a 21’ Dayton</ST1:pa all day long with a 300xs with the above set-up.
