I had a 1999Dt225 hp efi bought with a project boat. I recenlty purchased another 1999 model same motor with no lower unit. The powerhead was blown on the first one. I noticed today after mounting both of them on an engine stand that the first motor is a 20" shaft that has the lower unit and the recent motor has a 25" shaft. Is it possible to change the middle shaft exhaust etc from the blown 20" shaft powerhead to the 25" shaft? Thanks for your help.

I sounds like you want to end up with a 25" motor. If thats the case you would be better to change the power head to the correct mid section. The
drive shaft can be swapped and the shift shaft, but that requires tearing down the lower unit. Which ever you wish to do..good luck
I'm wanting to swap the 20" mid shaft (not running) onto the 25" mid shaft powerhead that is running. I want to have a 20" shaft not a 25" shaft. Is it hard to change the running power head to the non running one?
I have abook and am mechanically inclined.
Thanks for your help, Garland
You should be able to swap the non running powerhead to the running powerhead, and all you need is a powerhead gasket. Swap it complete.
8 powerhead bolts and five between the cylinders, the book should show it. I think that would be the easiest move..good luck Gary
Thanks Gary, I will in the next couple of weeks sawp it out. I looked at browns point.com and was trying to see the gasket called powerhead gasket?? I looked under the exhaust gasket. It looks like there about 13 bolts needing to be removed prior to switching the powerheads out. I have a book and will look this Sunday. Besides switching is there anything else i need to pay attention to?
Thanks again, G.
