TRS nose cone worth doing?
just got home with my new old pantera. looking at that big fat ugly old drive and wondering if it is possible to make it slide thru the water any better and if it is better enough. orig power steering, not hydraulic. at least not yet anyway...only gonna be 400 to 450 hp this year. 5000 rpm tops this engine.

i had them on my boat for a while and i picked up a couple miles per hour although i did it mostly for looks. Then replaced a drive and took the other off to match so ive got two with the epoxy id let go cheap if you want to try it

Thats a old boat . Prob worth spending a little time on the bottom especially if you have tabs- square everything up . Fairly cheap speed potential , dang sure wont hurt.

I had them on my twin Trs Mirage race boat back in the 80,s did not see any speed. I have some on the Magnum I have now with raised Volvo driver same results. If there not put on properly there could be some determental results. If you look at many of the race boats running today in OPA how many have nosecones, not many if any. I there was some speed to be had they would all have them.
Raising up older drives like Merc Trs & even Volvo's to there optimum height & using today's props is were the speed is at. My Magnum I have now has old Volvo drives up 3" & Merc Mirage props, it works very well with or without the nose cones.

I put a nose cone on a TRS on a 1980 Spectra 24 , took it off soon after as handling was quirky ...my understanding since then
is the TRS drive is too deep in the water and a nose cone disrupts the hydro-dynamics .

The help a little over about 68mph in SOME cases, that's right from Tom at Hydomotive telling me they just allow the prop cleaner water, nothing else.... nothing to do with lift, or going through water any easier, he explained the whole reason for them to me, the reasion you feel a lift or speed gain is because it's maximizing the prop efficiency.... makes sense to me but he said most boats don't see any real gains worth the cost till over 70++

and what does a 24-7 need for 70 mph with a TRS? somewhere north of 600 hp? won't be done this time around. and it'll probably be bravo converted in the next year or 2...
