6 degrees on my boat equals about 11 inches at the back. Draft is greatly reduced over sterndrives. I would have to say that the bravos stuck down at least a foot below the bottom of the boat. the lowest point of the Pulse Drive is the tip of the rudder, about an inch below the bottom. I constantly amaze people with the depth of water that I can run in or how close to the beach I can park (see above).

Sorry not getting back to you Wally. My exhaust routes into the platform. Nice and quiet around the docks. Steers fine at speed.

Robbie, you a skydiver? Me too. C lisc. Where do you jump?

Mongo/ you wouldn't happen to know how far your prop center lines are relative to the bottom when the trim is set flat, or in other words the prop shaft is parallel to keel? Thx, Bob

Too Old, I think $20K would cover the entire job for twins. Including glass work and transmissions. Then you could offset that by selling your current drive setup.

They use a drop tranny to do the job so your engine location should be fine. I really wanted to run these in a new twin small block Pantera 28 but VB's boat was hard to pass up. Can't answer on the stagger- thew rear motor may be too close to the transom to move it over with a shaft and cv joints-

Call them- the guys at Pulse have been a huge help to me over the last few wks.

seems rather heavy from the web site specs page doesn't it? A single drive capable of 800hp weighs 250 lbs? I was wondering if any one has tried one on a single engine cat and if it would be even drivable around a dock? Would the extra weight over a bravo really hurt balance? Anyone know?

Call them and see. Their site shows some video's on manueverablity including backing single engines. The drive housing angles down directing water back under the hull in reverse. also- the prop is pushing the water that is guided on top and by a rudder on each side which gives more of a "vectoring" effect.

As for the weight- I don't know if 250 is with the tranny or not. What does a Bravo and full transom assy weigh? Don't forget the prop is further back too which will help with balance issues.

What kind of surface area does this setup need on the transom? What is the width and height of the twin assembly? and is there any sort of clearence requirement around it?

Heres another question......how does a pulse drive and a step bottom boat handle together? I'm talking about the whole tucking/not tucking of the outdrives during a turn.........does a pulse or for that matter a surface drive affect the turning of a step bottom boat like an trimmed outdrive?

Hey Wally, You have a project in mind?

I looked into putting pulse drives on my Super Hawaii last winter. I really liked what I saw, but they are just not for my boat. They would've worked with my staggered engines alright, but I would've had to remove my trim tabs. My tabs are mounted fairly close to the drives because of the large gusset of fiberglass going up to the swimplatform. I needed the extra room on the transome because I had to put the transmissions in an extension box. I didn't have room to move the engines forward.

Call them and talk to Tony. He'll take care of you.
