Post a pic of your drive...
I just molded on a set of bravo high speed nose cones on a pair of my trs I'm sure they will help a little bit,
but they look really cool resembling a speedmaster, I also cut off the factory trs skeg and welded on some new longer sleek sharpered more modern looking skegs I doubt will see any mile per hour increase but they sure look baad hanging of the back of the boat. christian

Post a pic of your drive after the work. Mine needs a skeg now and Id sure like to see what yours looked like after the nose cone addition and skeg replacement. Thanks.

IMO I would take off the other nose cone at that speed. I had my Formula running with out them. I blew a drive and my replacement drive had a cone on it. I lost a couple MPH. This was on a Formula 311.

TRS - LH with Hydromotive nosecone - for sale
TRS Nosecone - I have rebuilt TRS LH with a nosecone, thinking of selling it - Yes, let me back up that statement about external steering, its not very good without the rams -
I have a set of TRS drives (LH & RH) in great condition and one that I just blew the lower on (non-cone RH). Thinking about going without the cones until I get my external steering rigged - so taking offers on a LH with cone - or a LH without in good condition - PM for pix

By adding a nose cone to the drive you are essentially putting material in front of the pivot point of the drive. Adding extra side loading stress. Normal conditions the the drive and most of the stresses are trailing the pivot point. That is how I always thought of it.

I have a 35ss Sonic with 700sc hp running mid 80's bravo drives , prop shafts are low (7" below bottom of boat ) I added imco nose cones and lost 3 mph from the extra drag . IMO if the prop shaft is deep like most older v bottoms they do more bad than good

Nosecone mods
According to Todd at Hydromotive, the speed improvement is 1 MPH@70 and 2 MPH@80 I am torn as I have a spare with a nosecone so I put it up for sale on eBay - its a pain if you want to swap out a spare drive and need more inventory http://www.ebay.com/itm/221133311109...84.m1423.l2649
The real advantage is the prop slip goes from an average of 15% to 12% per Todd at Hydromotive. better MPG
