Hi. I would appreciate any comments good or bad on the Suzuki 115-HP four-stroke motor. I am looking at a 16 footer that re-powered with a Suzuki 2003 115 H.P. and I know very little about these motors (I know Yamaha, Mercury and Evinrude). Please comment on things like quiteness, power, reliability, or whatever else you want to say. Thank you very much!

Suzuki four-stroke motors have very high customer satisfaction scores. They won the JD Power survey last year. I did a lot of searches on various boating forums (the hull truth, etc) regarding Suzuki pior to repowering and the response from owners was overwhelmingly positive. I recently repowered with a Suzuki 150 and have been very pleased so far. Several others on this board have repowered with Suzuki's as well and are very happy with their motors. The only negative I have heard is that the dealer network is not as large as Yamaha or Mercury in some areas, make sure you have a good dealer for service.

The Suzuki 115 in particular is supposed to be a very strong motor. It is 1.9 liter displacement versus 1.7 liters for the other brands' 115. it is the same block as the Suzuki 140. The only potential [concern] is that I believe the Suzuki 115 may be slightly heavier than some of the other 115's, which may be a [problem] on a 16' boat. Check the weight of the motor on Suzuki's website, and more importantly, make sure the boat does not sit too low or perform poorly due to too much weight on the transom.

I am sorry, but this is completely wrong information. Suzuki did not "win" anything in the 2006 J. D. Power survey. The actual results are given here: aspx?ID=2006025

and they clearly show that HONDA was ranked first, followed by YAMAHA second in customer satisfaction in four-stroke outboard engines.

I don't understand how there can be any confusion about this.

Suzuki and Honda tied for the 4-stroke catagory in 2005 but Suzuki has dropped in points for the past few years.

Thank you for your posts. The motor I am looking at is a 2003 model. Any information specific to this year?

We've got a Suzuki 140 four stroke on our partnership Revenge 19. Almost five hundred hours in a season and a third with absolutely no problems. Good fuel economy, quiet, instant start every time, smokeless, enough umph for our old banana hull classic...I'd buy another one in a minute. We put in a new impeller and had a comprehensive "tune-up" at the end of last season at a large dealership near Sacramento (which is convenient for two of the three partners) without any problem. I'm not sure if there's a Suzuki dealership out where we keep our boat--Bodega Bay--but it's really no big deal as long as ones boat is trailerable.

I have a 2005 and love it. I had a 1999 and loved it until I got the 2005(different boat). My friend also runs twin 2001's and has never had a problem. Quiet, strong for a 4 stroke, and sip fuel. Cons...420lbs.

Er, OK jimh, Suzuki tied for first in the 2005 survey instead of 2006. Suzuki came in second behind Honda and ahead of Yamaha and Mercury in the 2007 survey. I hope this clears up the considerable confusion created by first post, which was obviously full of "clearly wrong information".

seahorse, Suzuki has not "dropped in points the last few years", unless the scoring of the survey has changed (which perhaps it did?). Suzuki's winning score in 2005 was 913, and Suzuki's 2007 2nd place score was 924 on a 1000 point scale...which was higher than any of the DFI two stroke motors. But I really don't know (or care) how JD Power comes up with these number scores.

The bottom line is the Suzuki 4 strokes are reviewed favorably by JD Power, and also anecdotally by those that own them on this board and others. I have been very pleaesed with mine in the short time I've owned it.

John--Thanks for your clearer presentation of the results for Suzuki in the J. D. Power survey of owners of four-stroke motors. I found your new summary to be excellent, and more accurate than the earlier declaration of Suzuki as the winner.

In general I have high admiration for the four-stroke motors from Suzuki. Suzuki was the first outboard manufacturer to switch their entire line of motors to four-stroke from two-stroke. And they were the first to introduce features like electronic fuel injection to four-stroke outboard motors. They also pushed the entire outboard industry to drastically increase warranty coverage when they made their motors subject to a six-year factory warranty. This was a big departure from the previous standard warranty of a year or two. I think all of these things speak well for Suzuki.

Suzuki motors do not have the nation wide distribution and dealer support that other, larger brands enjoy. This may be a concern. However, if you are fortunate to have a strong local dealer who sells and services Suzuki outboards, lack of sales and support in other areas may not have much influence on you.

Suzuki also appears to be moving toward support of NMEA-2000 instrumentation for their motors, joining other outboard manufacturers like Bombardier and Yamaha in adopting this new standard.

I have the Johnson (Bombardier) version of the same engine, and although I've only had it out a couple of times, I'm very pleased.

When at idle, the various rattles on the boat are louder than the engine. The guys at the dealership tell me that the only problems they've encountered with this motor occur when boaters try to start them when they're already running...a frequent occurance, evidently, due to the extreme quiet.

Hole shot is good (1976 Outrage 19) and top end is about 38 mph.

You'll love it, I'm sure.

Suzuki is also the one and only brand that use timing chain instead of timing belt in their 115hp line. Real chain is much more reliable than belt and it is almost maintenance free.

I have been running Suzukis since 1981, none of my engines have EVER been to the dealer but the dealer network by me is better than ANY other brand except mybe Yamaha. The ONLY time I step foot into my local dealer is to get waterpumps and maybe a new brochure. Oil filters and spark plugs I get at the local auto parts store.
