Anyone running 115 Suzuki 4 stroke?

[Bigshrimpin]

Anyone on the board is running a Suzuki 115 on the back of their 20? I've heard that the performance of the 115 is nearly identical to the 140's . . .

Performance should be simular since the block is nearly the same. I believe the 115 has 118.9ci block vs. 124.7ci block on the 140. Also the gear ratio is higher 2.38 vs. 2.59 on the 140 so a boat running the same prop should have a higher speed at the same rpm. My twin 115's top out at 6000 and the 140 would top out at 6200. Sorry I don't have realworld #'s for the 20 but I hope this helps. My simple gues would be 2-3mph difference max. Here is the link to Suzuki http://suzukimarine.com/sr06/df140/f..._and_specs.php

I do not think you will notice a substantial difference.

One thing the 140 has that the 115 does not have is a beefier trim/tilt system. The 140 has a seperate trim and tilt where the 115 has one ram for both.

The DF-140 also has a oil cooler.

I'm interested in this topic as well (see my post on 11/30/05 under Repairs/Mods).

I happened to come across an old post by Finster (dated 11/02/04 under the Performance section) where he said he had a Suzuki 115 on his Aquasport, he was pleased with the performance, and had no doubt that it would perform well on the 20SC when he swaped out the motors.

Finster, if you are out there, did you ever do the swap, and how do you think it worked out?

[Finster]

I am not quite sure what your asking? I did swap-out a VRO110, and the numbers where better allround with the zuki.
You also have to keep in mind the Aquasport is a much heavier boat than a SC20.

I just sea trialed a 20 master Angler with a 2002 115hp Suzuki three weeks ago in a heavy chop .. With four adults on board it performed beautifully . Owner had run the motor for two seasons and loved the performance.
Will be able to give more personnal opinion after I run it down to the Keys and fish it in March.

Finster,

I'm trying to get some idea of performance in a 20 with a Suzuki 115 4S. For example, what's your cruise and WOT speed and RPM's (ideally speed measured with a GPS), that's all. I understand the SeaCraft and Aquasport are different hulls/boats.

RJO208,

Was the ride in Barry Centraccio's MA, and what were it's cruise and WOT speed and RPM's during the test drive?

Finny .... I think dcobbett is referring to you being all amped up about buying a 20 SC some time ago and your plan was to take your engine off the Aquasport…the 115. Remember the boat Brad took a look at??

Unless there is another "new" vessel in the Finster fleet …. the last I knew the Aquasport still lives !!

By the way the aquasport gets pushed along real nice with the 115 ....

Scott,

That's just what I was thinking.
