It's always a buzz when shopping for a new boat. It's a pretty big investment, like a small house dollar wise when you get to 30 plus range. Just to give you some hysterical perspective (as Earnest P. Whorel would say!!) I invested in a new 2000' Maxum 3300SCR equipped with 350 MAG MPI BIII's for a total of 600 ponies (the most sought after power package for my boat), she cruises at 36 MPH while slurping down 1.2 MPG turning 3650 RPM's (as indicated by the onboard fuel computer). Top speed is an astonishing 48-49 MPH with a fuel burn that is too depressing to mention but still amazing for a 33' aft cabin cruiser. Your 4.3's are lighter and less thirsty than a coupla small block V8's in either 5.0 or 5.7 liter, but the torque is less as well. Torque translates to faster on plane speed and ability to maintain plane without slipping off to a sub planing speed due to a heavily loaded boat.
For that reason, I would suggest that you require that the boats gas and water are full so that you can fairly put the boat through its paces for testing on water. You may want to bring a few passengers with you as well to again represent what your real world boating load will be.
Like I mentioned in a previous post after owning a half a dozen different boats, A boats total HP is like sex, way too much is just right. The smaller mills will have to work harder to achieve the same cruise as their bigger brothers, so too will the longevity be lessened as a result.
Since you looking at a long term relationship with your new boat I would suggest getting the most bang for the buck. Just my two cents…..
Good Luck with the Sea Trial.
