I know there are warranty and insurance with a Re-flash and HP increase of a motor, but how should we feel about hanging a 300HP plus motor on a boat that was originally designed and rated for a 200-225HP motor. Should we worry or is there enough fat in the design where it is not a issue. Obviously dead weight on the transom doesn't change but how about other forces with 50% plus more HP. On the other hand never really worried about it when you hot rod a car but you do tend to break more stuff.
Other question is what data is is on the ECM that is deleted or changed with the re-flash. Does it understate hours on motor when either buying or selling?
