LS to SS ?

Can a long shaft motor be changed to a short shaft?

Yes, you will need parts though....

It's much simpler to leave the motor long and buy a $200 jack plate and raise the motor.

And it keeps the motor away from the bad stuff more to "what TC said"

Most jack plates provide 7 1/2" of travel, that would leave only 2.5 inches to play with...Seems like a waste of a jack plate to me....either way...do both

There's 7.5" of travel in the jack plate. There's 5" of adjustment on the motor. That leaves 7.5" to play with.

Ok, so a jackplate with trim and tilt would cost what?

Verses buying some used parts if I could find them. What parts exactly?

Wevans would that T&T thing you have jackplate it too?

Also the boat is a alumacraft allwelded 1542 John. I was told by the local dealer that it could hold a 40hp, though it is rated for a 25. But they sell the same boat rigged out as a bass boat and rate it for a 40hp.

I am thinking about rigging a center console with 40 hp. It's just that I need a SS motor, and the 40hp Nissan I have is a LS.

If I was gonna use the setup described, I would buy "or build" a non adjustable jack plate "around $110 if ya buy one. And no T&T is also a jackplate

Thanks

I checked out the jack plate, now will that t&t you have bolt on that and work?

Post by **wevans** » February 26th, 2005, 9:45 pm

Yep, but with a jackplate and a T&T added on to the motor you'll need to raise it another 2 or more inches to run right

"the further you take the prop from the boat, the higher you can raise the motor"

I just don't know........

Now knowing a little better what you're trying to do, if you put a T&T unit on a jack plate, you'll wind up with somewhere between 8" amd 12" of offset. Plus the motor will be mounted at least 5" above the transom, probably more. That would be a lot of torque on an aluminum transom. You might consider having a double plate made that would slide over the transom, rather than a jack plate that would offset the motor. That would reduce your offset to 6" with the T&T unit.

Exactly what I was thinking about the double jackplate.

Don't know if all that would be less than buying some parts and converting to a short shaft.

Will check on that monday.

Boy....that would be one fast bullet boat with a 40hp!
