a friend of mine has a 31 sonic and he is working on a 35 fountain (single step) in his garage right now. the boats are sitting next to one another. the sonic has a great cabin! the fountain has more engine room, and more room in the cockpit, but the cabin is smaller with less head room. to be honest they are similar in size, the fountain looks just a touch longer. personally its going to come down to what revs your engine!! you know what you have in the sonic, i think he 31 is one of the best all around boats. go look at a 35, touch it, feel it, ride in one, then make your decision... no doubt that a fountain is a sexy looking boat.

The 330 mercs are meant for cruising between 3000 and 3500 rpm. Above that you open the secondaries and they are not efficient above 4000 rpm. You may want to look at changing your ignition system first as an inexpensive way of improving your fuel usage. Getting a 35 Fountain does not mean you ar going to save much in gas though.

The fountain hull is going to be much more efficent than the sonics, he's going to have bigger motors running less rpm's to attain the same speeds he's deffinately not going to be spending more gas $$$$.... That's if he can help staying outta the throttles

This was my single step 35. It used to be called a lightning before the twin steps came out in 2000. With HP 500's it would run a tick over 80 - 81. The twin step version with the same power would run 84 - 85ish, although Reggie got 87 out of them at the factory with no load or fuel.

Im glad to read your reply. I wasnt sure if I was going to get bashed for posting that or what. I just find it ridiculous that people dont simply read the questions and reply with a simple answer.

He also asked this I think people that didn't have pictures were just trying to give him "information".

No harm no foul.

I appreciate all the info. I have never ridden in a 35 sonic. We may try to hunt one down close and check it out. I had several people send me PM's and offer me some ride time in their 35 fountains close to here. Even though I have ridden in one it is nice to get in others to compare amenities and ride quality.

i love mine 1996 35

Hey Robert, wasn't wasn't my boat!:D And sure as chit it ran those numbers!

Now this replacement Biotch is a whole different animal!!!

Either version, single or twin step Fountains are fantastic boats. Have worked some for a marina that sold Sonic for a few years, nice boats, but when it comes to performance and handling it's Fountain! Hands down!

Hey Peter, I'm pretty sure my 35 EX was a little better looking and a we bit faster than yours, but maybe that was just my imagination :)

Did you ever settle on a final winner on your prop search?
