Does anyone have a link for info on this engine. I think it would be perfect for repowering an 18' Outrage. I went to Suzuki's website, but there is no information.

Thanks for the info! Does anyone know how Suzuki stacks up as far as longevity in salt water?

I do not. But if they offer a six year warrenty option, and run seasonal specials with it at no cost, they have to beleive in their product.

I've owned a few mortor cycles in my day, and the quality of enginering/manufactoring has gone up very fast in the last 30 years. We all know the story, from copying to dramatic technial innovation in such a short span. Thus the oft refered to Harley protection act of 1984(4), when all resonably priced imports were 699cc and below. the japanese gig 4 rose to the challenge, and the 699cc bike they built were very fast, and efficent.

Honda started in this time frame experimenting with oval pistons in their 2 stroke V4 race bikes. and they were getting massive amounts of horsepower and torque out of relitivly small displacemnt motors (250 and 500 cc, I think). I stoped following motor cycles in the late 80's, after a few too many rasberries. But I've often wondered why Honda went with the civic block fot the 130, as opposed to say, a marinized 900cc V4, akin to the VFR 750F (perhaps the finest moter cycle ever made, IMHO). Or an oval piston dfi 2 stroke 750 V4, that put out 185 hp and weighed 350lbs! I'd name it the VFO 900F (Very Fast Outboard, 900 cc, with an extra F to emphasise how fast it was), and it would be candy apple red. Period.

Wow, I'm off on a tangent. If I buy an new motor it will be Japenese. I just wish Kawasaki were in the market, my boat would look so cool with twin Z1000 lime green outboards on it. I'd get some K&N filters, and it would SCREAM!

I want to stress this was not my opinion but a sales person who sold Yamahas listed engines in this order: What does every one else think?

1 Yamaha ( of course)
2 Honda
3 Mercury
4 OMC
5 Suzuki
There ya go. This should evoke some replies!
By the way I think I would consider the Suzuki 4 stroke when it comes time to repower.

1)Yamaha, Honda
2)Suziki
3)Tohatsu, Evinrude
4)Mercury

The number 1 and 2 positions are close for me.

Number 3 would be driven by cost, as I believe the 2002 FICHT's will be priced very competitevly to capture back some market share.

Number 4 is not really an option, after the Optimax fiasco experienced by Juris. Prior to that it would have been in the number 1 spot with Yamaha, bumping Honda to number 2 with Suziki.

Since Merc licensed ther 4 strokes from Yamaha, I've got to believe that they are going to be way behind the rest of the 4 stroke market in releasing a big block 4 stroke of thier own design.

How much does the 140 suzuki weigh? Last night I was looking at a yamaha brochure. It looks to me that thier 4 stroke outboards under 50hp are very close in weight to the corresponding hp 2 strokes. The 100 and 80 and 115 are close in a way to weighing about the same as thier 115 v4 2 stroke. If the suzuki's weight is similar to that of a 150-130 2 stroke I would go for it too! I was thinking that currently a 22' revenge or outrage would be great with twin 115 yamaha 4 strokes! Ahh! dream on! Well I have to wait to visit a suzuki dealer in the future. Does warranty cover corrosion on outboards? If it does great, if not, too bad!

Have a good holiday! Unfortunately I will not be boating! Hope many of you will!

Regards
George

Not gonna say which ones I prefer but Suzuki is the worlds LARGEST outboard engine manufacturer from what I have read. Unfortunately they have a crappy dealer network in USA(except west coast of FL). I had a 1981 Suzuki 140 and I bet you it is still running today, great engine.

BS, not that it really matters much, could you point us to the source that you quoted that Suzuki is the largest outboard manufacture in the world.

Woudl be interested how this data was compiled.

Thanks

I think it was in Boating or trailer boat mag. Was puzzled by it too. I also read it here(on this site).

Just read their website and nothing about it. It said they have been around since 1906, etc. They said they are the FASTEST growing engine manufacturer, maybe I read it wrong or it was published incorrectly. I would assume Yamaha as the largest just because J&E and Merc have limited international sales compared to them. I did read somewhere that only 10-15% of US outboard sales are in SALT water. That blew me away. Now you know why they huried on the emission testings, etc.

Suzuki is probably the world's largest outboard maker. They make alot of small engines. All the two stroke Lawn Boys and Toros are Suzuki. Think of all the river canoes in third world countries buzzing around powered by 2hp Suzuki outboards.

This may shock you, being such a Honda fan.

1. Suzuki - Suzuki now have had their four strokes out long enough to show their worth. Suzuki has now filled out their mid-range four strokes above 70HP. Suzuki also has a fair power to weight ratio for four strokes. If I were to repower today I would seriously consider Suzuki.

2. Honda - Honda still makes a great product, great design, and proven reliability. Still it has the highest weight to power ratio of all the four strokes. They were the only ones to offer the mid range HP outboards for a while, but now that has changed. If Honda is able to address the power/weight ratio in their newer models and higher HP engines they could be number one, alone at the top once again. Otherwise they are Very Close (like equal with) as it is, with some features that are lacking on Suzuki.

3. Yamaha - Yamaha has been known for making the best two strokes. And Yamaha has experience in the four-stroke technology. Even though Yamaha shares the same powerhead as the Mercury there are enough subtle differences to set Yamaha apart.

4. Mercury/Tohatsu - Mercury is still evolving in the four-stroke realm. Mercury is looking to be different and that will take time, and once that is done it will take time to get a good track record.
Tohatsu (Nissan) is the new kid on the block here in the US. They have background and experience, but not a known track record.

5. OMC (Johnson)/Evinrude - Bombardier has a long way to go. Even though they are in cooperation with Suzuki they are in rebirth. It will take them time to find their feet and to establish themselves in the four-stroke market.

I can't say I am totally correct in my assessments, only time will tell all. Who knows, what if Mazda brought out a rotary outboard engine, imagine the power to weight ratio on that bad boy.
Suzuki may make alot of engines, Honda makes more small four-stroke engines.

Apparently rotary outboards have already been done.
"OMC 4 rotor outboards raced about six times summer and fall of 1973, winning every race in U class (unlimited). For example, at the Galveston Speed Classic, they placed 1st, 2nd, and 3rd, lapping the entire field three times (a fourth rolled and smashed). Displacement was 122 cubic inches. Power was estimated at 330 hp. "

Thanks,
I went to the web site and did not see any products. I wonder why OMC did not follow through with production. I am not sure if this is still true, Mazda only offered the wankel engine with the RX7. Why did they stop offering the engine on their other models?

B Bear,

In Japan, I had a rotary in my 1970s Mazada "Familia" Coupe. 5 speed and it would haul. Start from a light was slow untill I reached 3500 RPM and then scream.

A guy in 240Z tried to get me to race, reving his engine at the light. Light changed and I pulled out slow till 3500 and then ran away from him till about 90mph where he started catching up. He was not happy. (Had his girlfriend with him).

When I was visiting my old home stay family, about a 6 hour drive away, I would stop at a gas station near the freeway entrance. Fill the tank half with gas, half with heating oil. Had an extra 20liter tank of heating oil in the trunk.

Get on the freeway and scream. Heating oil was much cheaper but worked fine at high RPMs. (illegal to adjust timing in Japan). When I got to the exit, I would go to the nearest station and fill with gas so the engine would run smooth. Same thing on the way back.

Great engine.

never knew you could run a rotary on diesel, cool! Yanmar used to make a 28hp diesel outboard but it never flew and weighed like 400lbs.
dgp posted 09-04-2001 04:42 PM ET (US)     Profile for dgp  Send Email to dgp     
Yanmar still makes the 27 & 36 HP diesel outboards. The 27HP meets EPA but not the 36. I priced a new one a few month months for a potential 15 Standard projectand was quoted 12 five for the 27HP version. I could have gotten the 36 if I wanted to go to Canada and smuggle one across the boarder. I passed on new however still looking for a used one.

Bigshot,

Not diesel, more like kerosene(sp?). Used in small stoves for heating. Engine could be "tuned" to run smooth, but adjustments were illegal to do and place you have to get into to do it has a seal on it. Had to have the car "inspected" every other year and a broken seal is not good!

Other than rough idling/backfiring at low rpm, ran great above about 3K.

Tsuriki

Sorry, off topic.

I e-mailed about rotary outboards, and here is the reply. It might be of interest.

Hello Robert:

Thank you for your interest in Rotary Power Marine Corporation products.

You may want to visit our updated website at <A
HREF="www.rotarypowermarine.com">www.rotarypowermarine.com</A> for more
detailed information about our products. There is also a data sheet that you
can fill out and submit. That will help us give you the best recommendation
for your application.

Regarding outboards, there are no outboard mounted rotary engines on the
market today. Our true four stroke engines (models 175c and 240Si) are
actually as light or lighter than two stroke outboards, and are small enough
that they can fit inside hulls that can't accomodate "conventional" piston
engines. We can offer a variety of drive configurations that may be suitable
for your application.

Let us know more about your application, and we'll see if we can help!

Sincerely,
Jonathan Lauter
Rotary Power Marine Corporation
