flushing honda 30

  1. please explain your techniques for flushing.

  2. thanks,

    Honda says to tape off water inlets if you flush with the ears or the connector. says air can enter the system and cause damage.

    wondering is any one has experience with this.

    Flush port on the honda is a capped screw in connector.
    It's above the water inlets on the lower unit.
    Using the flush port without covering the inlets
    allows the water to flow downwards and out the inlet covers
    instead of being forced up into the block. So, cover the inlets.

    I still prefer the tub method as it's quieter and allows me to verify impeller status.

    junkin35 I Love microskiff.com!

    I slap ears on my Honda 50 and duct tape over the small bottom inlet. Works like a charm and hasn't let me down yet. I don't use the tub method because I usually flush at the marina, campground, etc and can't carry tub with me everywhere I go, where the ears just stay in my boat.
  6. what happens if you dont tape the inlet?
