Doc and Tony, that looks great!

Tony, I'm still looking for just the right project for those drives.

Just to show you how simple it is, Tim and I did the install in our spare time about 20 hours including filling the old holes.

When the sales Dept can do it any one can

My only question is regarding Tony and Tim with the rubber gloves??? Is that really resin in the pot Tim?

Looks great! And, how does it run???

Mongo

Interesting project! Looking at the 'after' picture, it looks like the "swim platform" over the drives is hinged (or otherwise articulated). I'm assuming that it moves with the drives, right? If so, can each drive be trimmed individually, or is the whole shootin' match moved as one unit?

Can't wait to see how these things perform....

The hole drive system trims as one

the aft underside of the drive works as a big trim tab at slower speeds hold the bow down and gets the boat on plane faster.
the curve underside of the housing directs water flow under the boat when backing allowing better thrust giving greater maneuverabilities

Have a look as www.pulsedrive.net for more info or call me direct at 954 788 0810

P.S mongo, the gloves are to keep my hands silky smooth, the late nights alone with Tim and resign fumes haven't pushed me to the other side

Any test time yet?

Panther:
Testing this weekend, and next week. we will report the results here.

Wow looks good. You going to leave both swim platforms on?

Hey Doc,

Boat looks great!!! Can't wait to run with you again in the Keys this Fall!

Curtis

Audifm: I am keeping the aluminum swim platform and the "other" one is actually part of the drive.

Curtis: Thanks for the compliments, I know you were thinking of doing the same, now just wait for my results and maybe you can do the same.

Well tell us, don't keep us in suspence!

Well ???

Could not finish the boat last week so testing this weekend. Be patience my friends, you guys will be the first.

????? Paging Doc! Just keeping this alive.

Just curious Doc, why this drive versus Arneson Surface Drives? I don't know much about surface drive except the ability to increase speed, more fuel efficient, durable.

Got to keep this alive! Tony, Mongo, Doc?

Don't know any news from this weekend. I know he is having a nagging fuel leak problem...

Mongo

Went out testing on Saturday and found that the fuel pump regulator was crack and leaking fuel.
On Sunday we got it fixed and now the port engine is acting up and today we will change to the original ignition box and test again.
So far the drive is GREAT:

1) I go on plane faster and easier with no need to use the trim tabs.
2) My children are save now when we go to the beach , they now go on board through the drives.

Top speed is not there yet and we will try bigger props in two weeks.

Any updates on the Pulse drive conversion??? I saw your ad in the new powerboat mag and it didn't list the pulse drives.

Please share the perforance difference.

We will try different props this weekend and I will let you guys know.

DR. Santiogo..........

What did you do with the old #3's?

The yellow would look pretty trick on my purple transom. Plus I keep having problems with the TRS not hold power.

Thanks

OBNOXUS21:

I sold them to someone with TRS with the same problem you have.

Hey Doc,

How is the project coming? Anymore on the water tests? Please keep us posted!

Curtis

With this weather I have not been able to do more testing. Hopefully this weekend.

I saw the boat in Ft. Meyers, it truly is a nice looking setup.

The props looked a little thick, any chance of getting the props labbed?

Let us know how she goes?

Doc, Saw your boat @ pulse, looks great! Good luck with the new drives I think you'll love them.
I liked you new exhaust tip, how are they?

Hugh

HebertNecessity:

The exhaust tips are great, finally I can run the boat without ear plugs.

The exhaust tips in action

Hey Good Doctor,

How is the project coming? We will be back down in Florida for Stu's Key West run in November. Can't wait to run with you again buddy!

Curtis

I am curious how this worked out. Is there another thread that comments on the final results?

I watched this thread when it first started wanting to see what the results were.

I take it by their silence that the project has not been a success.

I guess if they had gone faster they would have stated this by now. Same conclusion about the other customer that posted here from the Bahamas they’ve never said they went any faster.

I'm running 70.5 @ 5000 rpm with my rig. Pair of 520's. I'm shaving a little more cup off to get to 5300. Should see 73-75 (GPS, BTW). How many Cafe's with that HP go that fast? Maybe Boatless should get one (a boat) and try for yourself...

Mongo

imongo, impressive results!

I hope you are having a great winter. if you remember what winter is.:rolleyes: ;) :D
