New member looking for info on a recent project boat I acquired. Its a Texas scooter style aluminum boat with what I consider to be a oversized jet tunnel. I've seen one other hull similar to this but didn't get a look at the tunnel. From what I understand, several were built in the 90's. It currently has a 50hp Yamaha prop motor 25" shaft on it due to the tall transom. With out measuring it, its aprox. 16" wide and 18" long and 3" tall. Most tunnels I see are very narrow and around 2" in heigth? Will the addtional tunnl width be a problem with performance? It's a heavy built 13' hull, no sides, and a deep key slot transom. It currently will cruise 24mph with a top speed around 30mph with a prop. Any idea what the performance would be with the 50hp Yamaha jet? A F60/40 would be my choice but adds 60lbs from what I've read and aren't cheap. Trying to upload photos but having difficulty.
