Ok, if you have "captains call" exhaust then you need to replace the bellows with a exhaust tube. This is called for in Mercruisers service manual. The tube might be there if the captains call was installed at the factory. Tilt your drive up and look underneith of it, you should see a large bellows thats the u-joint bellows and the lower one is the exhaust. The small one on the right side has the shift cable going through it. If you see a "tube" that is open and seals off when the drive is down then you need to look at a diffrent prop that prevents blow-out?
Will the exhaust tube help limit this blow out? How is it different from the bellows when the drive is down? I'm assuming that this (http://www.go2marine.com/frameset.js...egoryId/13618/) is what your talking about.
Thanks for the info....
Details: I'm running thruhull exhaust, i have a sound selector, but, I don't need it or use it. My exhaust ports are below the water line. I currently have the bellows installed and get the same blow out that has been talked about in this thread.
what was the question
What benefit does the Exhaust Tube give you over the Exhaust Bellows?

I dont think you have a choice the newer drives have the tube
and its only connected on one side you dont have the problem of the bellows cracking with the tube
performance wise there is no difference
if you have transom exhaust you dont need ether the exhaust port will be capt
What benefit does the Exhaust Tube give you over the Exhaust Bellows?
Probably never rots. If you have through-hull tips, I'd just put a cap and clamp where the bellows were. Cheap enough.
However, the bottom line is I think you need 4 blade prop. A band-aid may be a bigger bolt-on cavitation plate...but a 4 blade will give you more bite.
Is there a specific part you can buy to cap the exhaust line?

I'm sure there is a specific cap out there...but you probably could just measure the diameter of the exhaust (probably 3" or so) and look for a plastic pipe cap at Home Depot. A stainless clamp will hold it on.
However, I wouldn't cap the exhaust before getting rid of the Captain's Call- it could spell trouble.
I want you to say these words with me:
"FOUR"..."BLADE"
Four Blade........Four Blade........Four Blade.......
