Rocket,
I was looking at your lower unit when you were in line at OKC, is it a CLE? The skeg mod is interesting. Have you ever blown this lower unit out? It seemed to be working just fine at OKC, so why change?
Skydog,
You can change a Bob's to a Titus, but I don't see much advantage other than the Titus cone is 100% welded on and the Bob's is spot welded, epoxied and filled. Also the Titus uses the hidden water passages instead of the hoses. The only reason I'd change is if the Bob's kept cracking, otherwise I'd stay with what you have. The advantage of the Titus is that he modifies a sportmaster, with a mod that works well. He also has a good mod for a CLE and 200 case.
