If I'm not a tournament offshore fisherman, why do I need a 23' 24 degree deadrise boat to go 59mph? I mostly fish the Cheasapeake Bay, and would like to try an occasional off shore trip. Fuel consumption and $7000.00 difference for the 225's is another factor. I'm told twin yamaha 150 four strokes will push this boat in the mid 40's, but I don't want to be under powered.
nothing wrong with running in the mid forties. i would look & see what that set up would do with a full load out of the hole & up on plane. i am not a drag racer at all but i think you need a boat that can perform with a full load .
Fully loaded with fuel, water, four persons, all our fishing gear, and the curtains up, we clock right at 37 knots in flat water. No problem getting up on plane, or pushing through rough conditions.
Grady Islander 270, with a bit less deadrise but heavier and more wetted surface overall.
Assuming the listed weight of the boat is reasonably accurate, I would guestimate the top speed w/ twin F150's to be mid to upper 40's (mph) dependent upon load. I fish a similar boat (similar length, weight, & deadrise) on 40-mile+ (one way) offshore trips regularly, and have never felt under powered. If I typically fished several people and with a full livewell, I might would want more power. But typical ocean speeds are usually ~30 mph or less, as dictated by running a small boat in "average" sea conditions. Faster speeds will send a smallish boat airborne too often (unless seas are calm). Part of the equation is to be sure the right props are on the boat. Perhaps the older heavier model of this boat justified more power.
225'S are totally unnecessary on this boat. BUT.....got to admit I have a hard time staying off the throttles. It's a blast. If only gas was $0.50/gal. I personally think 200's would be ideal power here. 150's should be more than adequate though
the 150s aren't really going to give you much of an advantage gas milage wise. the main consideration is if you want to spend the extra money up front. People don't belive it but if you look at most yamaha test on their site between the 150s and 225s on the same boat the 150s are usually are only slightly better on gas at speeds which you'll use it (30 to 35). you'll be up around 4000 to go 30 with the 150s and only about 3500 with the 225s. That being said there is a big difference in price between the 150s and the larger motors.
I have a 23' Sailfish with a Single Yamaha 225 (22 to 24 degree variable deadrise). Full Combat load (Gas, 3 people, tackle, ice and food) I can make over 35 miles per hour at around 5500rpm (+/-). Twin 225's on a 23' boat is wayyy overkill, twin 150's is IMO still a little too much for what you list as an application. Twin 115's I would think are more in order. Remember, the more motor, the more gas, if you get twins, double everything you can think about. Good luck.
Are you sure about twin 225's? Maybe a single 225 or twin 150's??????

"War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse. The person who has nothing for which he is willing to fight, nothing which is more important tha his own personal safetly, is a miserable creature and has no chance of being free unless made and kept so by the exertions of BETTER men than himself"

I HAVE SEEN THIS BOAT WITH TWIN 250'S, THIS A BIG 23' BOAT, ITS MADE BY KENCRAFT. THIS IS A 4000LB BOAT WITH FULL TRANSOM BRACKET. THIS BOAT IS MARKETED TOWARDS OFF SHORE KING FISH TOURNAMENTS .
I understand that the 150 are somewhat underrated, 300 to 320 HP's should move a 4000 lbs boat quite nicely. You don't need more than that unless you are a speed freak. After all, how many times you find flat seas to go all out. I own a 22 footer Mako and it is hard for me to go much over 30 to 35 MPH, except in a small protected channel that I cross in less than 2 minutes and where I can see 45 in the GPS. Save the $7,000, and also the additional fuel and the added maintenance of 4 extra pistons.
