Islander;

It seems like we have the same probs, i have been talking to other people using the 300hpdi and they have the same probs.
Yamaha told me that it`s the hulls construction that makes cavitation around the gearhouse.
Osprey have been installing 250 that been running without any probs and the 300 is the same engine.
Yamaha Sweden told me that they never heard of any probs with twin setup 300hpdi and they could`nt understand why it happened to mine.
I called a couple of friends that have the same setup (not on Osprey`s) and what, same probs 2 weeks before me "Yamaha never heard of the probs before, they say it`s the hull that makes the cavitation around the gearhouse and that`s why your engine does`nt get the colling"
Yeah yeah, a lot of bullshit, why don`t say we have probs with engine and we will try to fix it.

PS: They have been trying to solve the problem and been very helpfull but still "I want my engines to run"
Now my boat is standing at Yamaha for the third time in 5 months (engines been running around 380 hours in 3 months) 2 months on shore at Yamaha.
Sorry for my spelling, hope you understand what i mean.

Hi Manos
I have run the Yamaha F225 on a Ballistic 7.8 for 12 months and it was a very good motor with fuel economy. I also know companies running these motors and they are really pleased with them. The only reason I did not go for them was we purchased 3 x 10.5 metre ribs and we felt they would not have the grunt we required when fully laden with corporate clients. We are running 17 inch pitch props on the 250/300 hpdi's . This is needed when carrying 12 persons in the ribs but also allows the motor to run in the correct rev range without the motor straining under load.
I personally liked the F225 Yamaha and I recommend it as a good option for people looking for a motor in that HP range.

Why, i use 23 pitch pro series on the 300HPDI`s, i loose around 4 knots fully loaded (14 people) on full rev 5,600 (63knot compare to 59knots) and without engines running to hard i have 45 knots at 4,500 revs.

Hi Petrov
Yamaha are giving you BULLSHIT big time. I really do know that they are having massive problems with the 250 HPDI motors and the dealers and HPDI engineers have got their hands in the air. I spoke to an HPDI engineer very recently who said himself they are a nightmare and he would not have one himself knowing the major grief they are having with them. Yamaha, come out of the closet and admit the major problems and start giving your customers some proper support before you recieve some very bad press !!!

Hi Islander

You are very correct about the FICHTS (I gave you a greeny by the way so that we are all green ).
Any way the Yamaha enginearing here in Greece has been great to us. No complaints what so ever.
The 115s 2-strokes we have on the hired RIBs have been great too no problems what so ever and have very low consumption too so our clinets are happy.
The SCORPION will be used for recreational purposes rather than to charter out. Too nice boat to hire out.
My engineer told me that the 150F are very good no problems so far and he recommended (provied that they fit on the transom) to put a twin set. But as I said I'm very skeptical about the 4-strokes marine engines.
Any way will have to see.

PS It seems that Ballistics 7.8 will be our next choice for hired RIBs. What do you think about the boats? I haven't been on one yet but I'm gpoing to visit their factory in SAfrica to see for my self. Any objective info highly apreciated.

Islander;

I know they are giving me bullshit, that`s what i am saying in my last post, the only thing that is very strange is that the 250 are running great but not the 300 on the same boat

Not at all, just that we have`tn been having any probs with them wich is very strange because it`s alomst sam engine as the 300.
We have been talking to Yamaha about this and they can`t explain it.
Yamaha say`s wrong oil you have to use the Yamalube oil wich is the only oil that will work for the HPDI (it`s a new oil that is transparent) do you spell like that, and i heard that Yamaha has big probs with their oil and that the recomend the quicksilver optimax oil for the engines.
What the hell should i as a good client to Yamaha believe when i hear different stories from Yamaha dealers.
I have today 2 X 300 on my transom, that`s almost like 2 Volvo V40.
We accept that a boat engine brakes but not that a car engine brakes, why do we as a boat dealers/owners etc etc except this.
If the car brakes down we get fucking crazy but when the boat engine brakes we just accept that a boat engine always brakeas as they do.
Brrrrrrrrrrrrrrrrrrrrrrrrrrr, i get mad, sorry my language when i say fu....

Hi Manos
Our 7.8 Ballistic produced at Ballistic Marine, Hayling Island was superb and I sold it to Ionian Yacht Charters in Greece. The SA builds were abismal, they have or had no quality control either. I know someone locally who bought a 7.8 MAKO Ballistic from SA and on investigating that the fuel tank had split after several months, it was found that the whole hull had de-laminated and the boat was US.
I do not not know what the final outcome is but this is very disturbing would you not say.
I believe Nick Parish at Ballistic Marine, Hayling Island is still producing the 7.8 for customers and I would recommend the production of a rib from him as I know they do produce a quality product.
PS. We have had 6 Ballistics in the past. The Uk boat being the very best.

One other thing Manos since you ask.
The 7.8 Ballistic was probably the best rib we ever had,. It's sea keeping abilities are second to none. It's a smooth and safe ride and the reverse scallop chines produce amazing handling. I have used these boats with twin 225hp motors and they are amazing.If I wanted one rib for my own personal use and pleasure I would go for this craft.
Speak to Nick Parish in the UK at Ballistic Marine. I am sure he would do you a good deal and you could be assured of a quality craft.
