Worked very well. Cost was $6500US to New Zealand.
can you post a few pics of the frame you made? thx, rm

I have a magnum 27 sedan that had twin Yamaha 250 ox66 2 strokes. The fuel economy was not great we could maybe get 2.5 miles per gallon on each motor running @3500 rpm's. We did not set the boat up to go really fast because a 15 year old was driving it but the boat would do 57 on a good day. Recently we put twin Yamaha 200 in-line 4 4 stroke outboards on the boat and it runs beautifully. The boat only lost 1 mile an hour and we gained fuel efficiency. We get about 4 to 5 mpg per motor easily. We ran the boat in a 3 to 4 to green turtle Bahamas from palm beach inlet and only burned about 80 gallons so the boat is much more useable now!!!
