i have a 23 seacraft that i am restoring and since i have the transom being redone, now is the perfect time to repower. i am thinking of putting twin 200 efi mercs on a armstrong bracket instead of repowering with a 300hp i/o mercruiser horizon.has anyone put 400 horses on the back of their seacraft and if so how was the performance and what was your top speed?. i have also been told that 150 twins is quite ample for this boat even if i am running offshore.is it worth the switch or am i blowing alot of money to get the same hp as the new horizon 300hp.i was told that using twin outboards reduces your hp rateing by almost 30%. fuel efficiency is a major problem since i only have a 60 gallon tank.i can put another 50 gallons or so in the fish box in front of the gas tank.
