I have a '89 88hp rude w/ a 20" shaft. Can the shaft be extended to 25"? The engine runs great and am looking to get a different boat. Is this possibe or even a good idea?<br /><br />Thanks........

Howdy, FBT.<br /><br />25" shafts are commonly used as aux. on sailing vessels.<br /><br />Your lower end and drive shaft should interchange with that of a 25" engine.<br /><br />Good luck.

JB,<br /><br />Right now I have a runabout with a 20" transom, I am looking into a boat with a deep vee hull that would require a 25" shaft. Can my engine be extended to 25"?

You will need a 25 inch exhaust housing, and 25 inch drive shaft.

Re: '89 88hp evinrude spl

So it can be done? I'm thinking of doing this because I got a good deal on the engine and it seems to be in good shape. Is this a job I can do myself? I replaced the waterpump and thermostats without a problem (I'm pretty handy). Are any special tools needed to replace the drive shaft? Does the shift rod also need to be replaced?<br /><br />Thanks again...........

freebeetony,<br /><br />In the least you will need to:<br /><br />1. Change the exhaust housing-this is complicated, it requires basically dismantling the entire mid section.<br /><br />2. Change the driveshaft.<br /><br />3. Change the shift linkage.<br /><br />4. Change the water pick up tube-again this is complicated-requires powerhead removal along with #1.<br /><br />All of this as a minimum. I'm not sure if crossflow V-4's were even available in 25". If they were, used parts are going to be rare.

FreeBeeTony,<br /><br />I'm still not sure if the crossflow V-4's even offered a 25". I would secure parts before I took it apart.<br /><br />You may want to hail Dhadley, John from Illinois or Joe Reeves on this one. Those guys are closer to the actual product offerings that OMC had.
