Warren,
I don't know if your familiar with the 2950, but it was a great boat with bracket mounted O/Bs. But believe it or not, some "brilliant" person back in the 90s decided it would be really neat to build it as a twin I/O and a twin I/B! And the I/Os were tucked under the transom! That person should have been shot long ago!

I have never climbed around on one but the pictures I have seen of the twin I/O version gives me nightmares in terms of access and maintenance. But, if you could buy a used one at next to nothing and repower with a single VP diesel I/O and get a high twenties cruise and 2-3 mpg economy..........with a clean transom and a big livewell tucked into a corner. I have given it some thought!
