the part between lower unit and motor

[Zac]

I have a 70 searay sunfire it used to have a 65 hp mercury but i replaced it with a 90hp mercury. The problem is that the part between the lower gear unit and the motor is to long(I think it is called the driveshaft case but I am not sure). is there a way to get a shorter one? <br />thanks alot,<br />Zac

Yes there is but it is very expensive.<br /><br />you where probably supposed to get a 20" shaft and you have a 25" shaft. <br /><br />I had this problem and I solved it buy purchasing a "lift jack" or "jack plate"<br /><br />I got mine on Ebay used, but you can get them at any marina, <br /><br />They look cool too!!
