"Javier, I have visited the redlineweber website and it sounds interesting. I have never tried those kits, but I find some of their claims a bit difficult to swallow. Their claim of better idling sounds reasonable to me, but increasing torque and horsepower by 21% and in the meantime lowering fuel consumption sounds a bit too good to be true. To substantiate their claims, I would have liked to see them providing some dyno test figures as well as the specific fuel consumption figures for the Weber and the Solex arrangements, all tests conducted by independent third parties. But in any case, if their claims are true, you should get some extra 25 HP out of your current engine, which means you should be able to run with a prop 2 to 4 inches higher in pitch; and, while the boat gains a few knots in maximum speed, you should also see a decrease in your fuel bills.
If you go for that conversion, and after testing your boat, perhaps you would like to share your experience in the forum so that other boaters who may be interested know what to expect. Good luck."
