My take on those is this, The point of twins for many people is safety and security knowing if one fails you can make it back home. Knowing that there are several things to consider. One is Seatow or Tow boat US, tows you from just about any distance for a low cost of 149 a year +/-. The other is that with engines that small if one fails the other will get you home but no faster then if you had a 10 or 15hp kicker motor. Twin 150's may plane you individualy but not 115hp. My preference is always a good reliable strong single and either seatow or a good kicker. Twins will burn more fuel then a single, weigh more , take up more room, cost twice in maintenance repairs, and for similar HP are slower. a single 300hp would push a 23 almost the same speed as twin 200's or 225's with half the fuel , maintenance costs. My opinions only, but If I had my choice I would opt for a Single 225-300 hp engine, my 23 Savage has a single 225 efi yami and with 5 people and dive gear for 3 including 8 tanks, will still run 30mph no problem, at 4400 rpm and burns about 16gph it burns much less with less weight. You spoke about spending 4-5k I have seen several 4st motors in the 225 250 range that have reasonable hours for just a bit more money. A well maintained 4st will last you 3-4k hours np. a 2st about half that at best but the price to repair/ rebuild is usualy less. OR buy a new Suzuki and finance it
