I think his numbers are out to lunch. Specs for twin D4”s are 36 mph max (off sea sports webpage https://seasportboats.com/boat/pacific-3200/) and i believe those yanmars are higher hp than a d4. either that or propped completely incorrect. 6bt is a Cummins engine so would be interesting to find out exactly which yanmars they are……Im still confused by the 14 knot cruise...although
This thing is heavy at over 16000lbs!
With susuki 350s they report cruising at 30mph, top speed 41
With volvo D4s they cruise at 31, top speed 36
Pursuits 345 weighs 16000 with twin 350s and cruises at 28 mph, tops out at 46.
Another comparison is the 3400 express from pursuit, higher horsepower but similar wieght, cruises at 30, will do almost 40 with light load.
Maybe the yanmar setup is underpowered? Or something went wrong during the submersion and hasnt been corrected.
