A New engine

Roy Smith · 31 October 2004, 18:18

I am at the eleventh hour of buying a new 8 mt rib i want this to be a long term boat 5/6 years plus But what engine to put on the back.
I have a 225 yamaha four stroke that as never missed a beat on my exsisting rib. But what realy is the best engine should i look at
2 strokes, but as we want to go cruising next year will it give me the fuel economy.
to give a back ground, we do a lot of wake boarding, the rib is keeped at home. and on a normal year we do about 150-200 hours
I realy would would aprecitate some honest advice
Regards

Well if you do a lot of wakeboarding I would reccommend new tech 2-stroke ie: Optimax, HPDI, Ficht. It will give you better hole shot for pulling out a wakeboarder/ skier.

The 225 Ficht is soon to be replaced by a 225 e-tec which is supposed to have outperformed the new Verado. You can't go wrong with an Opti either but I would say that!!

Hi Roy

Have you read this thread about Yamaha HPDI’s ?

http://www.rib.net/forum/showthread....light=300+hpdi

If your concern about fuel economy is cost rather than range don’t forget to factor in the price of the 2 stroke oil, I read a thread on here (but can’t find it just now !), about the oil consumption increasing quite dramatically over ¾ throttle.

Do you not think the Yamaha 225 4-stroke would be any good for wake boarding on the back of an 8m RIB ? Only ask as that’s what I have and was thinking of giving wake boarding a try next season !

for single engine setup stay away from the big block yamaha hpdi,s

my best choice would be
250 xs optimax
evinrude etec 225 or 250
then fourstokes
suzuki 250 fourstoke
yamaha 225 is low on power for 8 mtr rib

for double engine
best choice
150 yamaha 4 stroke 4 cilinder 2700 cc light weight x2
150 hpdi yamaha x2 or 200 x 2
150 opti or 175 x2

I have a 225 Yamaha four stroke on the back of my exsisting rib and it pulls my 6ft 3in son out the water with no probleam as i said its never missed a beat and gives good economy but they are quite a bit more exspensive than a Honda or Suzuki,and old on the technoldgey
(i know i spelled that wrong but the wifes gone to bed)
I know there is the mercury but i have had bad exsperiences with them and if some thing did go wrong i would kick my self, even though there are plenty of rib.net people that sware by them. Untill a week ago i was all set for a Honda? but thats anouther thread,Its just that five year warrenty is very tempting.
As for the two stroke, after reading the threads on the 300 hpdi Hummm

Had the good fortune to race with a Honda 225 last season. Very nice engine, dont forget regular servicing (by dealer) to maintain the warranty. Sorry though I am a lover of the Yamaha technology and when they eventually go out of warranty they are very nice to work with.

Roy Smith · 03 November 2004, 20:38

Have desided to wait till january for the new 250 Yamaha four stroke,
I know iam a creature of habit, and if rumour is correct you can extend the warenty to five years when the normal two year runs out.
Thanks to every one for there input

I can wakeboard behind my little rib with a 1987 yam 25hp 2 stroke! So if i can do it, I reckon 225hp might just be ok

!

Good luck if you try the boarding, its great fun.

Hi Tim

Thanks for the advice I will give it a try next year, I had the rear of the boat and A frame specially strengthen for skiing and wakeboarding off so it would be a shame not to at lease try it !

Great photos on your website by the way.

Pete,

Yeah give it a go, takes a while to learn how to do it but after that its great! I go out off Yarmouth at 8 or 9 in the morning before the sea breeze comes in and the sea is mirror flat. Then again in the eve with the sun setting...I love the summer!

The only bit of advice I can think of right now is start with a shorter line (50 foot), its supposed to make it easier.

Anyway, thread has gone a little off course...apologies!

I thought the Mercury/Mariner Verados are suppost to give the economy of a four stroke with the acceleration of a two stroke.

TIM · 04 November 2004, 16:08

I think its Clever Advertising.... Four strokes with the acceleration of a 2 ... but not necessaryly the fuel economy!!!!

I think the new Etecs are better on fuel than the varado .......

gingercoastie · 04 November 2004, 16:19

Yeah maybe, but Verado sounds better than E-tec.

listen,im not exactly a rib owner,my dad has a rib and i wakeboard behind it.we have a yamaha 115 fourstroke,,its a beuatifull engine,as for wakeboarding that engine pulled up my dad 100kg on a monoski,thats even faster than for wakeboarders,with the 115 it can easily pull up any wakeboarder...i recommend u get it,we do alot of wakeboarding about 5 hours a weekend,the problem is the wake of a rib,its not exactly big enough for doing jumps.

Only 2.5 years late

For my recently purchased Redbay I opted for the Suzuki 300 four stroke.
My Reasons were as follows
High power to weight ratio
Economy
Engine ergonomics..you have to see it to believe how small they have made the engine.
Digital controls. -huge improvement on cables
Integration of Data feeds with other instruments

As a cabin rib K'ado is heavier than most but the 300 handles it super

Check out www.redbayboats.com or K'ado in the rib.net gallery.

best of luck

Look at the 250hp test in ribmagazine issue 68 (2006). The fuel consumtion on the suzi was wrong in this number should be 44litres/hour at top speed, not 24 if i remember right.

Yamaha 4-stroke was best in acceleration and e-tec nr.2

Yamaha or E-tec...
