Okay since the top gun question thread was getting a little too big I decided to spin off on this particular part of the boat since it seems to be the hinge of alot of discussions

Okay ultimately all of us or most of us would want those yummy #6 dry sump drives with extension boxes hanging on our transom. Sure for 90 grand in drives, boxes and props would be wonderful but definately not in the cards for all of us.

So these partucular boats i have been finding with 3's 3a's (very few and far between) TRS (most of them) and some bravo boats.

Which drives on a boat give you a measure of comfort and why?
I have heard that having a transmission like 3's and trs shift very nice, no clunk nothing. and the transmission moves the engine forward some to not have the boat porpoise as much as the bravo boats.
Im guessing the 3's have the same deal, engine more forward so less porpoising involved.

one salesman informed me the top gun was designed around the TRS for performance, and when they switched to the bravo drives, that is why they had problems with the full cabin, just engines too far back, with full cabin the boat was a dog.
so to eliminate weight they came up wtih this covergirl cabin to lighten up the whole boat overall and get it back to respectable performance numbers after 96
With the introudction of the twin step later on that just enhanced the performance of the rig even more.

So the pending question now is what drives would you choose and why?
Which do you think performs the best in your opinion?
And imporantly what type of boating would you suggest the different drives for?

my preference is for a #3a drive personally but now with that limiting factor im looking for a needle in a hay stack, add to it the mild blower motors and stainless headers and full cabin for 100 or less and im looking for a needle in a hay field.

What do you guys have to add as input towards this debate and what would you choose?
I might end up having to go to Tim and have a boat spec'ed out and built or buy one and have it modified to my liking in order to overcome some of these changes or "wants" on the list that I want.

Drives

Jason I will take the bait We are using SSMV drives to handle the high horsepower output of our ski race boats over the years many were using SSM 2 drives which worked well with Chev and ford 350 cubic inch motors however when using big block Chevs and eariler 427 H & M Fords the gears and bearings were not holding up under the higher touque Ihave not had much to do with TRS drives down under the SSM111 drives were matched to blower motors with good results bear in mind our ski race boats are only allowed to be max 21 ft in length with the advance to turbo charged motors SSM3As became popular as big gain was lowering motor height 6 inchs and transome mounting heights allowing better center of gravity for balance of the boat installation of transmissions in some cases improved out of hole pick up critical when starting skiers. SSMV drives improved drive durability with stronger gearhousings and support around driveline and bearings leasons learned over time have now made their way into XR Bravos although not recommended above 500hp the desired SSMV1 or six drives are the way to go when above 750plus HP dry sump version gains up to 100HP these are too heavy for our type of ski race boats however having crewed for a 43 ft race skater with 2 x 900hp sterlings work real well. Dry sumps were actually used on early Victory race boats using SSMV and SSM1V before the six drives came out propeller technology plays a major part in drive and boat performance this I will leave to other for comment
as mentioned in an early forum Mercury have been awarded a military contract for SSM 111 drives I can only wonder what these are to be used for I may have this wrong so do not quote me still if it is to protect the oil supply out of the gulf in middle east and our fuel supply for our toys why not!!
