Exhaust tube vs. bellows

[trm]

What are the pros and cons of switching to the merc option of an exhaust tube instead of replacing the exhaust bellows in a merc 120 (chev 153) and type 1 merc outdrive?<br /><br />About to renew the bellows so need some input from knowledgeable folks.<br /><br />TIA, Swabbie

The tube was actually developed for thru transom exhaust users. the bellows would draw a vacuum behind the prop and slow it down, so they developed the tube, as far as I know it backfits all models.
