Saves So Much Time, Perfect Fit On Mercruiser Pre-Alpha Outdrive.
This is a very useful kit. Perfect fit to exchange and align the gimbal bearing on a Mercruiser MR/Pre-Alpha Outdrive. The metal rods are strong and well machined to fit the gimbal bearing and the template lines up great with the housing studs. The overall production quality is very good. Great value because the tools are very durable but for me the biggest value is the time saved. I had the bearing out in about 10 minutes. The ability to line up the bearing before attempting to attach the outdrive upper gear unit is very convenient and saves so much time. This are simple tools, very easy to use.

Works well. You need to drill a 3/8” hole
Appears to be well made, alignment bar slides in nicely. As stated, you need to drill a hole in the bar for the gimble bearing driver, the directions are not clear, what I did was before I take out the old gimble bearing, put an O ring on the bar close to the last step on the bar, slide the bar all the way in, then carefully slide the bar out, this marks the distance from the back of the gimble bearing to where the shaft on the outdrive bottoms out, move the O ring a 1/4” towards the stepped part of the alignment tool (this is so you won’t bottom out the alignment tool when driving the gimble bearing in) then slide the driver puck up to the O ring and use a 3/8” diameter transfer punch through the side hole in the puck to mark the bar. You need to drill a 3/8” diameter hole in the alignment bar, two V blocks, some clamps, and a drill press will make drilling much easier, after the bar is securely mounted and centered in the drill press, use a center drill, then 1/4” drill first, using plenty of oil, drill all the way through, then use the 3/8” drill, deburr both sides and you should be good to go. People complain that it doesn’t come pre-drilled, the reason is that not all out drives are the same so you have to fit it to the outdrive that you have. Fortunately, I have a machine shop at my house and have a jig setup with various drill bushings, but the method I described above should work for you. Just make sure you’re perfectly centered and secure before you start drilling.

Worked for Volvo Penta SX Gimbal Bearing
Very heavy tool, I was surprised. Pulled my bearing like it was nothing. Putting the new bearing in was a little more difficult as you have to drill a hole in the engine alignment shaft where it will work for your particular outdrive. Not hard, but it does not come pre-drilled as the required depth for each particular gimbal bearing differs by manufacturer and model. Measure your bearing placement before removal and check that it was installed correctly in the first place. The bearing should line up with the grease fitting and the o-rings on the drive shaft should end up riding in the middle of the bearing. once you have your measurement drill the hole, I used a drill press. I suppose you could use it on multiple outdrive models as long as you can drill more holes.
