Sheeesh, I can hardly afford to keep my boat driving on the surface. :rolleyes: I just read this because you were calling out to my people wink .

I run a surface piercing prop...Dickhead :D

[Boozer]

How does a surface drive operate?

[jlnorthrup122]

These are surface drives they work as the name states only 1/2 of the prop is in the water!

[Boozer]

What is the advantage to running a surface drive?

[jlnorthrup122]

minamal drag = faster easier! :)

[Boozer]

Right but only half the drive is in the water so wouldn't that also have disadvantages?

[jlnorthrup122]

Well in theory yes but the props are designed to run this way so no it is better this way due to minimal drag! :cool:

[jlnorthrup122]

$$$$$$$$ they are not cheap would be my guess! I realy don't know. steering might be a bitch around the slip? Arneson is a company that makes surface drives.

When a prop is turning only the bottom half is needed to screw through the water and propel the boat.
The reason everyone does not have one is that to work they must be in constant contact with just the surface of the water. This takes a lot of engineering and is as expensive as all h*!!.

Srew rite but take a nut and bolt cut the nut in 1/2 now set the bolt down in 1 1/2 of the nut and spen it does it not thread? all you need is a load! surface drives work fine when completly submerged how do you think they get to the surface? I think alot of the problem with them is slow speed steering! :cool:

[oldphart]

you also have the advantage of getting rid of those pesky curtain climers when they're sliced and diced while swimming behind daddy's boat!

[jlnorthrup122]

Oh shit! hey boozer see my dealio in my sig thats a wiesman surface drive as well! :cool:

[Boozer]

So do you intend to use a surface drive on the aluminum cat?

[jet4fun]

from what i understand the biggest problem with them is price, and slow speed manuverability (in other words non existent) its like trying to parallel park a top fuel dragster...
i know one guy that has a pair of surface drives on a skater mounted a jet drive outboard on the back of the boat and covered it in a case so you cant see the outboard, it is mounted on hydraulic jack plates to lift up when it isnt being used. he uses it to manuver the boat around the docks
to be honest with you i still am really confused as to why they are not more popular. i have also asked the same question many times about the #6 drive... i just dont understand why someone can spend $150,000 plus on a brand new twin blown cat, and then puts some cheesy beefed up derivitave of a bravo drive on, and then proceeds to blow one up every other weekend.... they say the reason is money, but wait a minute idea you just spent 150k on a boat, you couldnt afford a few more bills to make sure you arent gonna smoke a drive... besides, once you've repaired that bravo a half a dozen times you could have bought the #6 anyways, and so in the end the #6 would have been cheaper :confused: duh

[jet4fun]

p.s. about the prop being halfway in the water... thats how hydro's work, and hydro's are some of the fastest types of boats out there, so it must work idea

at this time I am considering surface drives on a single bigblock! so rite now yes! I guess you could fix the manuverability problem by placing rudders behind the props. then they would funtion like v drives! :cool:

[burtandnancy]

They steer just fine, single or twin...

[jet4fun]

burtandnancy:
They steer just fine, single or twin... if thats the case then why did this guy go through all the trouble of mounting a hidden jet drive to steer the boat around the docks :confused:
and also this makes the reason of why they are not more popular even more confusing

[burbanite]

Surface piercing drives have been around for a long time, they are very efficient. The fact that part of the prop is out of the water and not "driving" is negated by the gain from less drag.
Great for speed, not so great for your average, run of the mill, doesn't use the boat in the open water type. Definitely a "big boat" deal.
Now days, offshore racing has more classes that are bound to rules that dictate the use of Mercruiser products and such like, surface piercing drive units were very popular a few years ago when it was more open.
Nothing says "Offshore Hot Boat" than Arneson...IMO that is...

Ok Hoss are these better posts? :D wink

Plus,
Props are several thousand dollars each, and they break from time to time.
And, no reverse. I knew a guy that ran a 23 ft. Eliminator with an arneson. He actually rigged a couple trolling motors on the back corners for maneuvering around the dock. Those drives were the biggest hassle on the boat.

Surface drives require a transmission. Get the right transmission and they have reverse.
Some boats do not have room for one or they need a standoff box.
They are hard to rig on a single engine tunnel boat.
They can be dangerous when you shut down from 110 MPH or faster.
The drive is not hanging in the water to act as a big rudder.
Other than that they are the shit.
the Pulse drive of the new Arneson drive are trimmable.
Bury the prop to take off and trim it until the bottom half of the prop is working once on plane.
need large rudders to steer the boat.
They have more tendency to prop walk because of not having a big drive to act as a rudder in the water.
