2010 225 pro xs with less than two hours run time. engine and jack plate are low as they will go. 30psi water pressure at 5000 rpm and up. but when you go in a curve it will drop to 0 sometimes .but when i called merc to see if i could plug top 3 water intakes they told me it would void my warranty. AND now that they are aware of the problem, they red flaged the engine.which means if i plug them i void my warranty AND if i dont its sure to have heat or water pressure codes stored in the ecu so will they even warranty it? what should i do?
