It takes a lot of horsepower to drive a 233 over 70mph. They are very heavy. I think you might save a lot of time and money if you save up for the killer motor. I'd recommend you go to a bravo for reliability. I'm using Alpha's but I'm very careful with them. You'll need 23" or more. Engines are nothing but air pumps so good exhaust is critical. Good luck and keep us posted.
Good evening Richard!
I was just browsing through some of the various threads on this site and I stumbled into this one. The "Surface Drive" portion of this discussion is what caught my attention.
I too am a speed freak but I plan on "Settling" with this particular boat. I am planning on running this boat offshore and along the Colorado River and Lake Havasu. With this in mind, my goal is to build the hull to ride smoothly through rough water. That being said, top speed will most likely be second or third on my list. Rough water handling and durability are my primary goals.
With regards to the single engine surface-drive installation, I remember "Schiada" built a single-engine 21' River Runner years ago. I think this hull was set up with an Arneson drive but I cant remember which drive they used. I recall the speed and handling to be pretty good though. If you enjoy performance boats and know anything about Schiada, you know that they build their hulls as good if not better than anyone else in the boating industry. They are rock-solid boats and they are capable of handling whatever amount of horsepower the lucky owner can afford.
Sorry to go off on a tangent; it was just an interesting topic in your discussion.
82 Formula: What was your decision? I'm looking at building a 500-550hp 383 stroker due to engine block weight and cost of performance parts. Also thought it would be interesting to let you all know Ford has an Aluminum 302 block that would make an ideal performance engine for our rigs.
Originally I was planning on finding a reman Bravo one and have instructions to do so but didn't realize it will drop 1" lower if that's the case I will be replacing the transom and at 30 years old it's probably not a bad idea. Can someone help educate me on the exhaust. I live in Minnesota where it's illegal to run a switch to change from hull through so I have to do one or the either. Personally I don't want to listen to that noise for 1/2 periods at a time on open water.
Surface Drive system would let the 233 operate reliably with a High HP single engine.
As mentioned, the Bravo attachment system could work. Running twins in these hulls eats up a lot of room, (V8 twin) and not as efficient.
X Factor could play a part as well. I have a TRS, and one factor is the prop tech is better now, so maybe the TRS could get out of the water a bit. But you still have 2x 90deg power changes, and a Bravo would be expensive to run at that power level.
Of course...the drives are all rated at Tq, not HP. So I you jack up your max RPM to 5500, then the drive gets it easier. So does the engine.
