From the advise I have received on here, the preferred setup is a single large engine. I am sure a more knowledgable member will post more reasons. I went around and around with the same idea on my 23. My wife wanted twins but mostly everyone suggested a large single instead. There is less weight on a single as well as less drag, less fuel burn which I believe could be debatable and the most important idea would be can the boat even get on plane with one of the twin engine inoperable? I understand the appeal of twins from a safety aspect. With technology today I think you could get a hold of seatow about anywhere now a days! At least that was my thinking on it. I am going the a large twin bracket from hermco for the floatation with a single ox-66 250. Luckly I found a good shape 30" motor. I also have a25" motor of the same so If I ended up wanting twins I just have to pick up a 25" mid section for the motor and I can have twin 250's which would be a lot of power all that is needed is to redrill the holes on he bracket! Good luck with which ever way you go! The new Yamaha 300 would sure make hell of a good motor on a 23!

Thanks for the info, we run 70 miles to blue water fish so i'm leaning on the twins for safety, I have a 250 mercury efi right now. The boat runs 46 mph top end but the fuel consumption is not good at all. I am considering the 300 though.

Went from twin 250 yamis to single 250 Zuke and will never look back. The boat performs 200% better with a single.

Well, you can't run faster than with the single zuke out of the channel so other than short bursts of haul ass and terrifying chine walk at 50 knots.... I guess it ran ok. I actually bought the boat from a friend who had the twins on it for redundency......... and cause it looked cool too.

Moose is correct I went from twins to a single, like I bought a different boat. Trim response, performance everything was better. Guys down here run 70 miles all the time, Sea Tow will still get there about the same time and depending on seas tow you faster.

I have twin 115 Suzuki 4 strokes. The boat runs 25.5kts at 4000 rpm's burning total 10.5 for about 2.8mpg. 5950 rpm's runs 38-39kts.(44mph) I love the setup, the weight keeps the ass planted in rough seas, I can keep her on plane at 16.5kts in nasty seas.

Combined weight is about the same as a Single 350 yamaha. Weight is manageable but at or near it's limit. A single 300 is the way to go IMO.

Go with a single 250/300, and despite the value of SeaTow, (of which I am a member and have been since 1984), if you're running 70 miles offshore, put a 10hp kicker on that puppy. After all, SeaTow can break down, too, or be occupied with other assists, and even a little 10 hp kicker will bring you home in 10-12 hours.

Trust me on this. I've been there & done that.
Once ran home on a 15hp Chrysler kicker on the back of a 25' Robalo from Memory Rock north of Grand Bahama across the Gulf Stream to St. Lucie Inlet (62 miles), then down the ICW to Palm Beach Gardens (21 miles). It took 12 1/2 hours, at 90% of full throttle all the way, motor never even hiccuped.
