Same block, but it stops at the block.

For an oil setup what about doing something like they have for cars with the dual remote filter setup and mount it on the transom and maybe a oil cooler like for a car with an electric fan on it by the air intake into the engine compartment.
The Marine oil cooler setups use the infinite supply of 70 degree lake water (supplied courtesy of the sea pump) to cool the oil not a remote radiator- like a car.

I know right now that boat has a cooler like that but its for the power steering. I wonder why it doesn't have a stock oil cooler

Because the components form the factory are scaled (cut back) to the amount of power they put out.( 350HP) at crank or prop?

350HP<max> of heat input to the oil is a lot different than 500HP of heat input to the same 7 quarts of oil. The cold water is a godsend at this stage.

Which stock autos sustain this level of output?

(think of the strain of the bearing AND how much the rod has to push. )

This is from an article.
The Velocity 230 shares a hull with its sister craft, the Velocity 22 with which Stepp won the 1985 American Powerboat Assn./Union of International Motorboating National Championship, and set a world straightaway record of 77 mph with twin 200 hp MerCruiser stern drives

I think blowers look awesome in the engine bay but I would have to cut out my hatch and have it come out the top.
From what I have seen around here I gathered this info
my boat with the 350 mag/alpha should run around 60 with the 330 7.4 run mid 60s and with the 454 mag run around 70. I have seen guys say with a good prop they ran 73. There is suppose to be one in ontario with a 502 I think its stock that runs about 80. I read on here one guy hitting the 90s but I haven't been able to find the thread again
Lots of info here, Ill digest this slowly.

Blowers extract an extraordinary cash input to live at all, from your description, but done well are superb. 75% of guys do it cheap and it deosn't work for the long haul.

Velocity- I respect this MFGR.
Solid super fast hulls, above average rigging, and good poeple. Their rep is great, so Id gamble the hull will take whatever you throw at it within reason. (steering aside)

You can rough an additional 1MPH per 20HP at the prop.
5MPH will equal about 100HP from your baseline.

Factor in youll lose 3-4 MPH just switching to the bravo.

Which lower are you considering, thought about that yet?

For now I want to use the standard bravo 1 drive and I would like to build another stronger bravo on the side also. hoping to use a bravo x or xr upper for a base and I was thinking a shorty lower. this will all still take some research.
Do you know if the braxo X upper will bolt to the standard bravo 1 gimball?
I know during this time regal had the rights to velocity.
I know ill lose abit from the bravo but ill need it when it comes to a bigger engine. plus right now my alpha is in need of alittle repair.

Hardin, Teague, CP and Dan olsen, and others all sell great coolers.
(I have an Aeroquip)

FYI- Chrome plating as cooler "costs" a serious amount of performance.

Do run sea strainers? this was something else I was thinking about.
Chroming usually weakens the part too
