Install / removal video by Tech service rep Wayne Coll

This video was shot as a high school project by daughter Justine Coll about 10 years ago. At this time we did not sell or service Mercruiser outdrives or bell housings, this was our own boat.


My wife purchased the 28 foot twin engine boat at an auction and booked mooring at Ontario Place in Toronto Canada with out even looking at the outdrive or engine.

My job was to fix the boat in 48 hr. so kid can have a air show party.

People who purchased the above also purchased the following:
