2006 Mercury F9.9EL (long shaft) to short shaft conversion

[RipNLip]

Hey guys. Just a quick question for ya…….Has anyone on here converted a long shaft motor to a short shaft? Specifically a Merc 9.9 four stroke? What is needed for the conversion? Just a short shaft driveshaft housing and a “short” driveshaft?

I don't know, but that's what I'd think, should be fairly simple. That said, might be cheaper to add a jack plate or build up the stern by 5".

Just found out I need a shorter water tube pickup also. The problem I have with building up the transom is we have a 20hp short shaft motor we use for crabbing on the bay. I just bought the motor because my wife would like to go to 9.9 restricted lakes also. I found this motor and it is in pristine condition and for the price, I couldnt pass it up.

$800

That's a nice find, in your case you'll have to shorten the extension or go with a Jack Plate, assuming a Jack plate will give a full 5" lift.

If you add a jackplate, get an adjustable unit so you can adjust for either motor....a couple bolts is all to make that adjustment..

Around here there are always good deals on long shafts. Just bought a long shaft Johnny 25 for $80. Not worth converting IMO, bought it just for parts. A little late now, but you might still be better off finding a 9.9 shorty. Sure would save you a lot of hassle.
