Re: v4 omc prop

If the plastic ring you are talking about is where the prop meets the lower unit,you are probably referring to a weed guard(might not be correct name)that prevents weeds from getting sucked in and jamming behind the prop.It justs snaps in before the prop is installed.Fabulous device that can be added when prop has smaller diameter than the lower unit.

Hi Boatright.<br />The plastic ring at the rear of the prop is known as the Diffuser ring, its there to extend the exhaust gas far enough aft to prevent the exhaust gasses from ventalating the prop.

RPJS is correct. <br /><br />It is a diffuser ring, and it does what he says.
