I am about to remove the flywheel from my 85 150hp Mariner V6. I have a puller with 2 arms that will pull from the outside of the flywheel (the ringgear). Am I going to stuff anything using this type of puller or do you specifically need a puller that bolts near the centre of the flywheel. The manual also tells me that a plastic cap should be used to prevent any damage to the crankshaft. Can anyone please give any advise. Thank you.
