Thread: Sonic 31SS
10-17-2008, 10:32 AM #1
Just bought this '03 Sonic 31SS a few weeks ago. It's a tank compared to my old 20' Baja. I already had it airborne off a cruiser wake and the landing was nice and soft. The wife and I look forward to many long weekends on the river with it next year. It has a head, fridge, and even heat/air conditioning. The best part is 850HP worth of 496HO's!

Very nice. Sonic makes a really nice powerboat. A friend ordered the 35 with the 500 EFI, and it was really nice. Pretty fast too, or so I thought. He didn't think so and worked out a deal with the factory (the previous owner of Sonic) to take is 35 on trade for a new boat. He custom spec'ed a 38. Standard hull and molded components, but the paint and vinyl was all custom that he and his wife designed. Boat also has custom Innovation Marine 800 HP V8s. The Innovations are pretty cool engines. Normally aspirated but with 800 hp and a fat torque curve. Innovtion mostly builds race engines and mil-spec engines for the Navy and US Customs. His are hybrid civilian and mil-spec. Like I said, interesting engines. Originally they were coupled to Imco / Max Machine Worx drives. But Innovation's torque was crushing the gears and breaking shafts.
Those are supposed to be straight splines. But the engine twisted the end of the shaft and tore the end off of what you see that remained. We were cruising @ 3,000 RPM in flat water when that occurred. I was right behind the helmsman and remember the conditions.
The boat's been re-rigged with Konrad drives, but now needs new props. Fortunately the Konrads can take the torque. Can't wait to see what the new props will do. There's a lot of performance in those hulls. And since the bottoms aren't stepped, they handle without quirks. Nothing scarier than kiting a cat or blowing out a turn on a two-step hull.
I meet a few of the old-time Sonic factory workers. Some of those guys remember every boat that ran though the factory. Most of them aren't with the new owner, which is too bad. Seemed like everyone there lived fast boats. BTW, if you want to go faster and have the money, you might want to talk to Doller Offshore Marine in Hollywood, Florida. They worked pretty closely with Sonic for several years and know how to get a few more knots out of the boats.

I added a lot of boat bling over the winter. Come on summer!
GPS speedo to scare the wife. I did give her a nice billet grab handle, though.
Custom-made billet steps
Locking fuel fills
To meet the stringent 84dB noise level in MN, I had to add mufflers and custom turn-downs. This also required a custom-made tie bar setup to clear the pipes.
