has anyone else seen the sc 20' cc in Islamorada with twin merc 2.4 offshores? It has been a few years since I saw it. I have witnesses. roughly 93 mph.

roughly 93 mph.

in addition to those twin engines, doing 93mph in a 20' SeaCraft would require smoking copious quantities of crack ahead of time.

I think the idea of it probably came up from smoking crack. It visually was not something that made sense so you can see my reasons for asking if anyone has seen it since. I wish I would have had a camera.

I'd be really surprised that the hull could achieve those speeds even with that power.

May 18, 2007 – Washington, NC – Fountain Powerboats, in a two-way average speed of 87.6 MPH, set the American Poker Run Associations (APRA) center console world speed record.

I am not sure that the guys I speak of know and certainly don't care about poker runs or records. The amount of work the hull had seen to hold this setup was significant. Aluminum right angle legs glassed in and such. I just wanted to know if anyone else knows the boat. Doesn't sound like it!

If you don't care about bragging rights . . . why bother to put twin 2.4L mercs on a 20ft seacraft. That doesn't seem practical at all especially with all the other hulls out there (that are designed for those speeds). You'd have to run at least 28 Pitch Props . . . and your idle 1000rpm would be tuna trolling speed. I'm sure it's fast, but I'd have to see it for myself to believe the hull could hit 93mph.

We've got a flats jockey down here that has a 20' Lake & Bay with A 300 Optimax that claims he runs over 90. It just might and the 200' rooster tail also looks cool. Funny thing is, with that heavy motor he draws more water at rest than my SeaCraft which means I can fish flats that he can't. I'm always on his case about having a flats boat that can't fish skinney water. Moral is , use the boat for what it's made for.

Redneck BS'ers. 90 mph in a flats and bay? I don't think so homee. Why not go to the Merc website? A 24 Yellowfin flats boat is the fastest at 64 witha 300 Verado. Recently the same YF 23 flats boat strapped on a 350 Yamaha and got 73 mph.

90 is a long long way off. I did 92 once in a 27ft progression with twin 300 promax merc's and it was really really scary. We made it from the St. Petersburg pier to the Bradenton Yacht Club in 16 1/2 minutes averaging 78 mph. It also swung lab finished 32inch props so in reality the flats and bay did 65.

Flats boat at 90+? Sure. Not too hard to do. Got one locally.
SeaCraft at 90+? Not without a complete redesign of the center deadrise toward the stern.

In 1985, I rigged a 20 MA for a lady lawyer with a Merc 225 that would go 65-66 or so after adding nosecone, jackplate, blueprinting the hull, etc.

We also rigged a 20 with a 3.4L Merc on a jackplate that we got to 73 mph after weeks of trials. It was flat out dangerous. The chine walk passing through 67-68 mph was extrmely violent, and required putting some down angle on the K-planes to overcome. It turned either a 28" cleaver or a 32" cleaver to achieve the same 73 mph. It just had different jackplate heights. The limitation was hullspeed.

I have ridden in a 23' Seavette with twin 235 'Rudes that would indicate 78 mph on the Airguide racing speedo. It was rock-stable at that speed. BTW, it would not get over 70 mph in flat water, it had to run in a pretty good chop to hit 78 indicated. Again, the limitation was hullspeed.

But there is always some nut who will strap a jet engine to a skateboard.

Locally, we have a physician from Tampa living in Homosassa who has a 16' Shypoke with a 2.4L Merc Bridgeport on a jackplate that will run an honest-to-radar 98 mph. In a race across Ozello bay, wherein both boats were also radared by a complicit Sheriff's Deputy, the 16' Shypoke positively smoked a 20' Talon picklefork running a 520 hp Mercruiser. The Talon owner had claimed a top speed of 108 mph. In the race, the Shypoke radared at 98 mph, the Talon at only 90.

It wasn't even close. The Shypoke just flew away from the Talon. We were in a chase boat that was a Formula 233 with twin 350 EFI Magnums, running our top speed of about 70 mph.

Let me say this about the Shypoke: it is a pure "Come-To-Jesus-Now" machine. I swear he was out of control half the time. But it surely did go fast.

So it can be done. But I think you have to be really stupid, or really young (and stupid). (Like I once was )
