Re: OMC vs HF flywheel puller

[Don]

The long bolts are used to pull some of the prop shaft bearing housings on the thru exhaust gearcases. That big spacer is used on some flywheels where the crank threads are way below the highest spots on the flywheel. Many of the new larger engines need it, along with engines like the old 60s V4s with the built in under flywheel alternator. That spacer is also handy pulling some thru hub bearing housings as well.
