300 Hpdi

pmorgan · 11 May 2004, 19:43

I have seen on a couple of threads that some of you have been looking at the Yamaha 300HPDI. And now that I have been able to get a more reasonable quote for it. I was wondering if anyone had taken the plunge bought one ?

Can't help you on the 300 but we're very happy with our 200 hpdi.

Are you thinking of putting it on your 5.85? If so, I hope you've got Teflon coated underpants!!

And a reinforced transom.

No – otherwise I would be wheelies like the Zap Cats at the Sports Boat show http://www.rib.net/forum/showthread.php?t=4738 .

I am do some research on engines for my new Scorpion.

Thanks

Oooh! Which one (8.1 / 8.5???)

Like your Blue-Ice website by the way – lots very useful information.

pmorgan · 11 May 2004, 20:04

Not entirely decided yet. Think probably 8.1. I have just reserved a build slot and I have 3 weeks to make the major decision like length, engine etc - Good fun but more stressful than work !

Thanks very much for your comment about our website. We love our boat and the only thing that could be better would be a bigger one!

Hope to see you out on the water once you get her - although we'll never be able to keep up with you if you get the 300!

Louise – Richard do you guys have his and hers PC’s or do have to fight for the keyboard ? My girl friend and I have the same problem with the helm ! No problem with the keyboard at present as she is still at work – someone has to pay for our new toy !

Louise · 11 May 2004, 20:10

Richard tends to use the desktop one and I recline on the sofa with the laptop! Whereabouts do you cruise? We are Solent-based.

We keep our RIB at Cobbs Quay which is in Poole harbour. Hoping to keep the Scorpion there when we get it.

Do you happen to know what sort of litres per hour you use on your boat ? as the worst case scenario for the that have been quoted are frightening and a real world would be useful.

250 HPDI - 75 lph
300 HPDI - 105 lph

Roughly 35 - 45 litres per hour, but we don't usually measure it per hour. We usually divide the fuel consumed by the distance covered which generally works out at about 1.1 litres per nm. HTH.

I have twin 300HPDI on my boat and my friend has a singel on a Seaharrier Max 7,4m.
We have been driving around 100 hours with them and they are running like a Rolex.
No problems at all except on low revs, the engine dos`nt like it, the plugs gets really dirty fast so after 20 min you have to drive a couple of minutes on high revs to clean the plugs.
Can definetly recomend the engines, i use Yamahas pro series, 23 pitch and my friend a Quicksilver revolution 4, 23 pitch.

Petrov thanks for the feed back. Good tip about the plugs – just the sort of thing that is not mention in the brochures !

Can you tell me if you have ever had a big Mercury Optimax (200+) as I would really be interested in the comparison.

Now you're just showing off!!

P.S. Only joking - cos I'm jealous.

pmorgan · 11 May 2004, 20:40

Yep thanks Louise. That sound more like. I must admit we usually recon on about 1l per mile with our existing boat.

Seen on your website that you have been to Alderney and the Saint Marlo – that’s one of the main reason for our up grade is to cross the channel, can’t wait !

We had 5 Mercury Optimax 225hp all of them crasched for us (know fixed) been having a lot of probs with them we changed to Suz 250 on the boats that had the merc and on the new boat in fleet we use the 300HPDI, why we wanted the HPDI was because we had a 200HPDI that runned for 500 hours without any problems at all.
We choosed the Suz because of a good price and the boats that has them are running around 800 hours per summer so it`s good for economy.
The Suz has been running around 80 hours today without any probs.
