How high above the water line should your exhaust be?
 

What is the min. acceptable height for the bottom of your risers to be above the water line? I am boating in the ocean and often stop and float in areas were there will be swells.

Thanks
Jon

Minimum 15 inches to the TOP of the exhaust header elbow. (This is from the HP500EFI Install Manual)

yea, thats what merc says. I am at 8" and sweat bullets everytime I have a crowd in the back of the boat. so far so good.

My regular service manual has 13 inches but was printed in 1996.

You ever get that boat over to the Madfish, or the Studio, or Wingaersheek, Brace's Cove or the Greasy Pole, or even Annisquam Market? . . . Back side of Cranes?

Just checkin. I miss the Rock (Gloucester).

Rouxsterre Ya I hit all those places. Unfortunatly this year it has been by land not sea :( Kind of had to put the boat on the back burner so that I could buy a house. :(
