Would there be a great difference in top speed by changing from nose coned TRS to #3's or Konrads. If I would only pickup 2-3mph it would not be worth it. I have 700hp+ hp and I know the TRS are a weak link but I have three spares so failure right now isn't an issue just more top end. Running 90mph+ now.

The Konrad TRS replacement is 1.7" shorter from input shaft to prop shaft. The majority of TRS conversions gain 3-5 mph in top speed.

Converting to a SSM III is a major re-rig. The transom cut out is different, exhaust mods and the motor needs to be moved back about 3", the trans tailstock is also different.

Running 90 with TRS, thats SWEET!! How many RPM's you turning and what size props?
Just curious

5700rpm and Bravo 34's There is still way more speed left in this old school ride. engines will turn 6,200rpm. Next year major test and tune till I hit 105mph minimum!
