TV ads for a Jetski. They show the happy jet skiers zipping around in blue water. Then we get to the meat of the ad, brakes. On a boat? They show their Jet ski slowing to stop in much less water than competitor jet ski. Cool. But why do I care?
You slow a boat by putting the prop into reverse and using engine power. To get into reverse you have to throttle back to idle. Shifting at full power makes that ugly grinding noise. Throttling back is likely to make the engine stall, leaving you with NO reverse thrust at all. I learned many summers ago, never to depend upon reverse thrust being there when you need it. Approach dock slowly, to avoid ugly bumping sound should reverse not be there.
Anyhow, I ain't buying a Jet ski just a cause it excels in reverse thrust.
