Super User Fishing Rhino Posted March 19, 2014 Super User Posted March 19, 2014 I have no idea, but some on here might if they knew the make, year, horsepower, etc. of your outboard. 1 Quote
tbone1993 Posted March 19, 2014 Posted March 19, 2014 Ouch, got to winterise that thing better. 1 Quote
BassnChris Posted March 20, 2014 Posted March 20, 2014 Sorry to hear that........I always winterize because that's what I'm afraid of. Were you using the boat in cold weather or was this just a result of water in the lower unit oil? Quote
Missouri Bass'N Posted March 20, 2014 Author Posted March 20, 2014 The motor is a 225 efi Mariner magnum, later got in the lower unit some how with a seal busting. Not gonna be a pretty fix! Quote
Super User J Francho Posted March 20, 2014 Super User Posted March 20, 2014 You're looking for a Sportmaster or Torquemaster LU. The Sporty is for top speeds over 80 ish. Pay attention to gear ratio as well. It's not as hard a swap as you might think. The tricky part is lining up the splines in the shaft to the receiver on flywheel. You'll want an extra hand to rotate the flywheel to get it aligned. Note the direction it spins when you start it - don't go against it. I'd say one way or the other, but I honestly can't remember off the top of my head. There's several vids out there that show replacing the impeller, and the process is essentially the same. Quote
Super User Way2slow Posted March 20, 2014 Super User Posted March 20, 2014 If you do a search, there are several, large salvage yards around. I try to avoid anything run in salt water but that can be a problem if you are not able to see if before you buy it. When it comes to Mercury technical expertise and parts help, Scream and Fly is good source. An awful lot of those guys eat, breath and live Mercury. If it is the torque master, it will be probably be easier to find than the sports master because of lot of the guys pull the pull the torque masters off to install the sports master because of the lower drag and higher speed rating. If it didn't distort the housing and none of the hard parts are rusted, you should be able to have it TIG welded and install new seals. If there are any questionable hard parts, it's about as cheap to go ahead and find a used one by the time you pay the parts and labor bill. Quote
Super User WIGuide Posted March 20, 2014 Super User Posted March 20, 2014 If you take it to a dealership, they could probably rebuild one for you using the internals that you already have and just put it in a new gear case. Quote
