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!
That is some great numbers. I assume that the prop has cup in it according to your numbers. You were running about 16% slip which is great for that size and weight with 7 people on board. If it don't have cup then you are around 10% which is bass boat numbers. Did you ever try to go WOT? You may have been there and just didn't know it? I'm at 12% with my bass boat Full load and two people which is considered a barge. A lot of speed hulls are down in the 5% range when running light.
Back to your trailer question. I never feel a jerk to release the brakes on my trailer unless I just pull a hole shot at a light. There is a shock absorber on mine that makes it release smoothly.
Just for the record, I run passenger tires on my trailer. The ride is a 100 % improvement over my original trailer tires. I put about 10,000 miles a year on my boat trailer also. I am at about 67% of the tires capacity on the sidewall.
