http://www.socaljetboats.com/the-no-wake-zone/school-me-on-dual-jet-boats/msg184027/#msg184027Here's a thread from last year about them. Hot Boat - May 2007, had a good article on dual jets. It featured Harold and some of the boats that were converted to dual jets.It talked about how they accelerated alot harder and cruised at lower RPM's. It didn't help top speed at all.There was a company called Trident boats that made a 29' deck boat with the dual jet option. It accelerated quicker than everything else that size, but would top out at about 70mph.
The article was great. It talked about the process Harold went through putting it all together, featured a few dual jet boat (including that one in the video, i think) and the pros and cons of it. Real interesting if you get a chance to read it.
