He has the best low cost motor on the planet. Nothing cheaper to rebuild than a old V-6 Merc. Those TOP are a complete PITA to reassemble, in perticular getting the rings to compress and fit into the bore while juggling 5 other rods, pistons and rings flopping around on the crankshaft... They all go in at once, special tools yada yada. They should be fattened up with todays fuel but screamers they were. IF I was going twins, it would be on a bracket, it would be Merc powered and they would be older V-6's. Hp from 150 to 225. Maybe a couple 2.4L mercs they were 389 lbs according to the sticker on the motor.
I won't get too technical, nor argue with anyone about it but the law states that any vessel 20' or more in length can have unlimited hp. That Coast Gaurd plate is officially in the garbage can. The man can't do a thing about it... USCG, Local LEO's, Dept of Homeland Security, NOBODY. Except for maybe a lawyer in court after the poop hits the fan and your overpowered vessel and operator are now to blame, irregaurdless of whose fault it was....
Destroyer, If you do the math and raise the transom up to 25", great idea. With twins you still would need 20" legs I think.. or the lowers would be buried in the water.
When I repowered with the new 4-stroke 115 Merc last year it had nearly the identical weight of the old 115 2-stroke Yamaha V-4. So they are more efficient motors and the weight is getting closer, in some cases.
