2 piece shaft to 1 piece shaft question on 300X

[jlay]

Guys, I am looking at a 20" lower unit that has a one piece shaft, problem is that my current lower has a two piece shaft with the coupling. Is this a difficult modification or is it just a simple part change out? Thanks in advance!

Simple change. I did it with two torquemasters for my 300pm.

Are you buying a different lower unit with a 20" 1 piece shaft and want to know if it will just bolt in place of the 2 piece shaft lower??
If thats it then its no problem as long as the 2 piece lower is a 20" also.

Thats what i mean. I have a 2 piece 20" sporty and am looking at a one piece 20" tourque.

It's a direct bolt in. You may have to change the 4 studs on the mid section to shorter ones. But other then that it will go right in.

How is it a direct bolt on? Is there another coupling closer to the motor that is the second piece of the shaft that I remove? The shaft on the tourquemaster looks longer than on my speedmaster. I am just looking at a picture though. They are both for 20" mids. I know I am going to have to change the studs to the shorter ones.

if the torquemaster is a 20" with a 1 pc. drive shaft it will go right in without any coupler.
The 1 pc 20" driveshaft is the same length as the 2pc 20".

Your lower with the 2pc drive could be used on different length midsections by just changing the upper shaft length.

OK that makes sense, thanks a bunch!
