The transom/shaft height debacle of 2020, HELP!
Ok, i'm being dramatic, but here is the scoop.
The boat in question - 2008 Boston Whaler Challenger. Brunswick Commercial outfitted this boat with twin 30" mercury's as the motors were provided by the purchasing agency. I've spoken many times with Brunswick and they state that their records reflect an application of 25" shafts for twins or 30" shafts for singles. HOWEVER, due to the high customization they offer, there is a world in which the transom bracket was raised a bit to accommodate the longer 30" shafts. I've never had the boat in the water as it came to me with one motor blown.
I am about to repower and may actually buy out of state due to insane CA markups on outboards. This means I have to get the right motors. Here is an image with some dimensions i've sent to a number of dealers/installers all of whom seem to come back with different answers to the question. Any help would be much appreciated.
