This tool kit made servicing the gimbal bearing and checking engine alignment much easier than improvising with generic tools. The machining looks solid and the tools fit properly with MerCruiser components. Helpful set for anyone doing their own marine maintenance work. Definitely useful to have around for sterndrive service jobs.

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.
