enjoy!!

 

great look'in paint job Blown Formula.

What motors are you running and what is the top speed?

First, here is a better picture... then the engines!

 

The engines.... full roller 468 ci BB Mark IV, 2.25 intake valves, (Other head work), single plane intakes, 1050 Dominators by Chuck Noone (flowed, etc), all forged stuff, Lightning Headers ( essentially dry pipes with internal wet mufflers by Lightning- the only set ever made!!). Water enters the exhaust about 1.5 " from the end of the pipes. These thing really cook even before the carb rework. Speed is unknown as I ran out of warm weather too soon.... I am hoping for another good day soon to get it wet again. The boat just made it into the water after 3 years of drydock.
Estimated 550hp each. 1.36 Bravo 1's, 26p Bravo 4 blades... What's that work out to @5600rpm??

 

Great looking motors, but I would think that you would need a bigger pitched prop with that much horsepower.

I'm looking at some new non-mercury props by a company called "Propco". They are designed by an older gentleman that was a chief designer for Mercury props for 25 years. He, in my view, has a superior product that will get you on plane quicker, faster accelertion, handles better and reach top speed. I tried a set on my 31 SS recently and gained 3 mph and had faster acceleration at 35 mph and it really threw us back in the bolsters.

If you're interested, I'll get you his web site. I'm going to put a 2" spacer in my lower unit part of drives and go with either the 28" or 31" Propco props and should gain about 5-8 mph.

The reason he needs to run smaller props are because he is turning a 1.36 drive ratio. That seems about right.

 

here is the website for the propco props:

Yes, I wondered about that drive ratio as well. That makes sense.

 

I just am starting with the 26" Pitch props... to see how I like the 1.36 drives. I have a set of 28" P also. If I don't like the speed or acceleration with the 1.36's I have a set of 1.50's also to swap with. Since I never had the boat in the water & the previous owner didn't either, I really had no starting place for sure with the increased power. My Formula 312 with Procharged 454 Mag's & 1.50's can run low 80's with the 28P. I think the Sonic is going to beat that hands down!!
I am just starting with "trials" on this thing.... it will take a while to iron it all out. We will see .

 

blown formula,

Have you ever weighed your Sonic 31? Sonic says that it weighs 7,000 lbs. without fuel/water. I weighed mine this summer with 1/2 tank of fuel and almost empty water and it came in at 8,240 lbs. so with a full tank, say around 8,500 lbs.

I do have some extras on it including, A/C refrig, electric toilet head, TV/DVD etc. Put I was surprised that it actually was that heavy.

I guess that helps explain why does so well in rough water.

 

I have a 2005 358 with twin 525's And really enjoy running the boat in the North and South Carolina Waterways.

 

I finally got around to checking out this forum. I'm Love Machine on OSO and I have a 1995 35SS, but it's with Trick Marine right now being brokered I'll have to post a pic later when I get home.

My other is a 340 Sundancer.
