I have a 1994 Aquatron C/C with a 3.0l Merc. I changed my prop pitch to 17 from 19 to increase my hole shot and WOT. Well Hole shot was outstanding and speed was 30+ but WOT not much above 3400. Merc 3.0 WOT is 4200-4400. I don't think the Tach would be off that far? Now I brought this boat back from the dead and I did all new interior along with some engine work. I placed the engine control module in the correct spot by measuring a similar boat. I assumed which is bad on me, that the cables are adjusted to the proper length. I need to do some more investigating and determine if the eng controls are opening up the carb all the way. I?m asking if I?m going in the correct direction or should I be looking at my worst fear of having water in the hull? Any thoughts are much appreciated.
