View Full Version : 9.9hp to 15hp evinrude conversion
Hi, guys I have just put a 15hp carby on my 9.9 evinrude (approx 1979 model) and have gained a truckload more power/speed. However I am just wondering if the carby is the only difference between a 9.9 and 15hp of this model or do other things need changing for the full 15hp. Any help would be greatly appreciated.
cheers
Mat
Also are there any risks of blowing the engine, as the motor rev's harder with 15 carb?
cheers

there is a lot of differences between the two, you will end up using a heap more fuel for your 'percieved" power increase.
