Re: Twin Yamaha F115s on a bracketted 23'?
 

Zukes run a lower gear ratio in the LU, not sure but might make a difference. 2 115's is only 230 at best as they are 4 S Yami's, I don't think its enough either.

If your main concern is resale than the single 250 would be the best. It all depends on how much you pay for the 250 and will it make up for the perceived lower value of a boat with twin 115's.

The benefits of the single 250 are lower maintenance cost and of course about 250 pounds less hanging off the rear end. The speed will maybe be 1-2mph across the board better with the single.

If I had to repower it would be hard not to buy the Suzuki 300.

In your area it is not unusual to go 70 miles off fishing. If many of your trips are that far, then the twins with one that will plane is the way to go. AND when fuel goes back to $5.00 plus on the water, more twin 115's will be had. Briguy's 115s are propped right and does 46 mph on GPS. Single 250 or 300 will be the best choice for resale and ride because most people aren't consistently taking a 23 off that far.

I've got more range than guts, that's for sure!

Re: Twin Yamaha F115s on a bracketted 23'?
 

I know the Zuk runs a lower gear ratio, i know of someone with a 23' with twin 115HP suzuki than can plane with one engine too.

if price is good i will go with 2 x 115HP. i have twin 135HP mercury optimax and i could not use all the power. Haven't tried to plance with one engine yet.

mine comes closer to plaining with one 150 than it did
with one of the 250's same props I tried it the first time
I ran it without the hydrofoils on the 150s might plain with the hydrofoils on now
