Yam HPDI 200 HP

Andy · 17 October 2002, 14:18

Hi all,

Just joined the group. Have been a RIB owner for most of my adult life, and love them. Glad to find a bunch of likeminded people. Not done long cruises yet but will do soon.

Now I am here I need some advice on a new purchase. I am dead keen on the HPDI 200HP from Yam, everything I read says, good performance, good fuel consumption with the responsiveness of a 2 Stroke. The 4 strokes I have used have been heavy for the power they deliver and didn't react very quickly when the throttle was dumped. Now I know this could cause a 2stroke v 4 stroke online battle. Thats not what I am after.

What I want to hear is people experiences of HPDI and this 200HP Yam engine in particular. I have not signed the cheque yet and its wise to seek advice from indepentent experts.

Anything you have you be appreciated

Thanks in Advance

I have a Yam 200 HPDI on my Scorpion and think its an excellent bit of kit! It is quiet, powerful and delivers similar if not better economy over the 150 Merc Optimax I ran on another RIB. I get approx 1l per mile at speeds upto 3/4's throttle.

The Yam's are more expensive than Merc Opti's - figure on a premium of £1500-2000 or so but I think they are better engineered - they are certainly quieter! Upto you whether you feel the premium is worth it.

Acceleration is good and I imagine holeshot would be pretty good although I've not pulled a skier with this boat as yet. I do have a mate with the same engine on a 7.5 Cobra and he ski's all the time & has nothing but good things to say about the engine.

Have had no experience of servicing costs as yet.

HTH,
Alan

If you can afford it, the Yamaha HPDI 200HP is the engine to go for without a doubt. My friend has two on the transom of his 9m White-shark and has had them since they came out. I have skii'd many times behind his boat, yes I know there it is a twin set-up but even so the 'hole-shot' is tremendous. The only consideration is getting the correct prop for your application.

Protector Ribs, in New Zealand fit them as standard and swear by them. Wish I could afford two of them

Hears a question. Who does build the new range of engines for Mercury?

Charles · 17 October 2002, 16:01

Go on then .............

who does ??

Julian · 17 October 2002, 16:16

Yamaha me thinks

Alan · 17 October 2002, 16:46

not least the HPDI's. Different technology from Merc Optimax - higher pressure for a strart.

Pete7 · 17 October 2002, 19:57

Yep, my money is on Yamaha, only because I think Alan P is asking a question he already knows the answer to. Have you ever seen him use anything else ?

Daniel · 17 October 2002, 20:00

99% sure it's a yam - yes different technology, but that don't mean different people make 'em!

It has to be Tohatsu !!

JK put the thread on fire with this question and we kindly

ASK him to post the answer too.
As far as the 200, one thing I know for sure. You must replace the oil every 40 hours of work time. This procedure can not be accomplished when the boat is in the water. It has to be on the trailor.
Thus, replace the engine oil BEFORE your vacation departure. Otherwise.......

Replace the oil?? On a 2 stroke???! Sorry Michael but now I'm puzzled. The HPDI is a 2 stroke engine so no engine oil. What are you referring too?

I thought it was Seagull who built them

Julian · 18 October 2002, 12:14

I'm sure Yam build the mercs to . I think Yamaha , Mercury, Mariner and mercruiser are all from the same company.

I have used a 150hp on a 6.5m Tornado and it was a fantastic package. Quiet, odour free as 2 stroke get and very responsive.

A friend (who used to work for Delta) had a 200 hpdi on his 6.5m rib and reported it was best thing he had driven at that power range. Confirm 1ltr / mile at crusing speeds, however, it is a 2 stroke and will drink oil as it goes which can be expensive unless you buy in a commercial drum.

As for Yam as a make, I would take one if I could fin d the preimuim, long-term ease of ownership and reliability are cost that are worth accepting.

Are you sure the Yam 200 / 225hp 4 stroke is too slow for you!?!?
Not much difference in the weight!
Very nice!

I had the impression that Yamaha build the block for Mariner / Mercury, not sure about the leg, but most of the other components are then down to the brand.

This was certainly the case for 40 - 60hp older models.

batfalcon · 22 October 2002, 09:49

I'm referring to the latest model of Yamaha. The 4 stroke one. Sorry for the confusion.

Alan · 22 October 2002, 10:07

was starting to wonder where I could stick a few litres of oil in my HPDI!!!

dgpw · 22 October 2002, 14:54

It is not evinrude or mercury.

the 200 hpi is a good engine, It provides a good power output and has a fairly steady tick over. The 225 optimax is my fevered but the injectors tend to be a little flimsy in my experience. The 225 ficht is a really good engine but is fairly complex in terms of the engine management system. Even so they have the best fuel economy for around and have a very high power out put, more than the 225 they claim.

Who does produce yamy now

Honda use the mercury leg and spray them silver the woman on the stand at ribex was explaining to me why their legs are better than mercury Ha Ha
