I would be interested in a pair if you could figure out the reverse rotation, have no desire to have reverse rotation engine,

sorry
i had a total brainfart on post 80.
trs reverses rotation in the lower with gear on carrier instead of in nose.
alpha 1 gen 2 reverses rotation in lower by simply running in reverse but the carrier is shorter.

Hello SlowRyd. I pm you yesterday. I want to shorten my
Bravo lower and I wanted to talk to you about
Getting a deep enough weld. And cutting down the vertical shaft. I want to run my drive on surface. Taken out 4" to do so.

Hey man I just saw this in my email. I can give you a call tomorrow to talk about it but I can tell you now 4 inches isn't possible. You don't have the space on the vertical shaft between the bearing and you prop wouldn't fit with a bravo upper. You would have to have the scx4 upper to have prop clearance.

Konrad 540. Much stronger upper and very similar to the Bravo lower

SlowRyd, what is the dimension you are looking for from the input shaft C/L to the prop shaft C/L?

Yea, that's an awesome effort, but considering I still blew a TRS upper after about 150 hours with 600hp (lowers only lasted 60-80), whereas my Konrad went 430 hours before the lower went (and I'm guessing that's cause I only changed the gear oil twice in 7 years). For me, anything over 550hp will never be in front of a bravo, TRS, or any combo of the two - just no damn fun.

Stay under that 550 or so and this is a great way to get more speed out of a TRS setup, for sure.

It sounds great ,would be alot easier than raising motor and drive on my 23 Daytona no room,,in my 4 inches below bottom,how would a 5 blade cleaver work on a stock trs? 330 Hp,soon to have more. Nice job Ryd

ever figure out how to get it to work with twins?

SlowRyd 02-07-2017 04:03 PM

Only option is a cam change to reverse the engine
