Well I have spent the last week dealing with my mechanic but we have not fixed the boat just made it worse...here is my prob...the boat is a 21ft welcraft with johnson 150 at WOT the boat would only hit about 4300 rpm trimed up and only about 18mph. So I called the mechanic he did comp and that was fine...but then checked spark and said I had no spark in #2 cyl so he imediatly told me I needed new powerpack so he replaced...did nothing then he said needed new optical eye so replaced ...did nothing please shoot me some suggestions any help would be great. Also when replacing powerpack , optical eye, and stator do they have to color cordinate...some have grey, some have blue and some are black ....thanks again for your time
