Do you have the knowledge and tools?

You can save a ton of money if you can drive the bearings off the gears.

Knowledge is the easy part, The special tools are what
will frustrate the heck outa you!!

IE: Torch set, retaining ring tool, pullers, press, shift
shaft seal tool... and the beat goes on.. [img]/forum/images/graemlins/tongue.gif[/img]

$1000.00 minimum in proper tools to do a proper job!!

You would be better off looking for a used lower in the
$350 range. Or see what a professional shop would charge. Just my 2¢ worth

See ya, Ken

I found a used lower unit but it is a 25 in. The guy says it can be cut down to a 20 in shaft. I had never heard of this before. Seems like a waste of a good lower unit. He wants 350 plus 100 to get it cut down. He also has used switch boxes for 50 each. I know what I have and what is wrong and I would rather not buy someone elses junk. I have never took apart a lower unit but I am willing to try.

Go to Scream - Fly tons of 20" stuff

also SEI makes after market new under a grand - nothing but excellent reprts

DO NOT ATEMPT THIS AT HOME - the parts are the killer, forget the tools

went to scream and fly will keep looking there lots of racing stuff.sei is cheaper then what some local companys want for a USED lower unit. my thought is,ine is is broken cant get much worse then that. thats why i was thinking of taking it apart myself.

Do SEI - honest their close to me and I have several people that bought them. On the .net just a couple issues but great reviews. Persoanlly thats the way I would go based on what I have seen on used prices - S-F lowers may have been used hard to, got to check what boat it came of off.

well i might of found a whole motor for 700 bucks. going to look at it tomarrow. or i could of just bought overnighters motor for 500 and he could of made 500 more on the boat sale too little to late.

Yep, I went SEI 130 engine hours ago. No problems at all. Easy install too. Every lined up and fit perfect to my 225 Yami. Very pleased with SEI....
