rebuilding lower units
 

anybody ever rebuilt there own lower unit(mercury)on there own. i have a had no luck for the last couple of weeks looking for a used engine. so i have decided i will keep mine and try to rebuild my lower unit my self. i figured if the unit is broke i cant make it any worse.if i have no luck rebuilding it my self then i will buy a used lower unit and go from there.

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

Re: rebuilding lower units
 

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.

Re: rebuilding lower units
 

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.

Re: rebuilding lower units
 

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.

Re: rebuilding lower units
 

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....

Re: rebuilding lower units
 

well after looking at a 700 dollar paper weight.i decided not to buy it cause the guy whom owns it would not hook gas up to it to make it run. so back to the grind stone for me, save some more money and keep looking.

Go to scream and fly you can find one there for 500
