Brand new boat & engine so breaking in things - mechanic quoted 6400 as red line - 44 was at 6400 rpm & not wot - boat came with a 17" & dealer rigged it out with 15"
Powell is about 3500' lower & I consider swapping out but decided to keep it rigged as is & see what happens. I've heard rule of thumb is 3-4% HP loss per 1,000', but the mercury master mechanic guy I use says supercharged verado pro only looses 1% per/k' … we'll see …
About the only concern with the engine is making sure I remember to turn it off with people in the water … the thing is soooo bloody quiet - we have to turn the tunes down when cruising at 4200 rpm to talk!
