Petrol V Diesel

Roy Smith · 30 May 2006, 23:46

Hi all
My brother is in the market for a rib, he is a diesel man and the question he as put to me is.
With all the tec there is why dont rib makers put Volvo D4 or mybe a
BMW 535 D twin turbo, which on paper should give near 2 stroke pull from a diesel in there Ribs. To be honest i have thought about it my self.
Any Comments.

The new range of Yamaha Diesel are in fact re-badge BMW motors, and are available in both 4 and 6 cylinder variants. The smaller 2000cc 4 cylinder one looks ideal for a rib. Had a test drive of a BMW with this engine last week and was impressed.

And yes fully agree that when / if they bring out the twin turbo 3000cc version it would not be slow

Where have you see these? Yamaha were exhibiting their Toyota based 3.7 litre 4-cylinder and 4.2 litre 6-cylinder engines at Ribex in May. http://www.yamaha-motor.co.uk/produc...t_segments.jsp

I think you mean the Yanmars. It will be interesting to see how these BMW engines perform but unfortunatly they will still be mated to the Mercruiser leg

It was either in motorboat monthly or in motorboat and yachting (ok so I can dream) will dig it out once I get home. But it was quite a big article on how Yamaha where using the BMW motors.

Did check the Yam web site and did not see any mention of the new range, just as you said the current Toyota based line up.

Roy shortly after the 10th June I will have a new demo rib , The Parker 750RS with the Mercruiser 320HP linked to B1 drive. When in LM after that date you and your brother can enjoy a test run

It's Yanmar and not Yamaha.

Hi Andre
Im new to the forum, but have made some experiences with the Merc in a
9,5m Tornado. Its a great engine, but we have had some difficulties.

You should check the engine mounts and reinforce them if you can,
our broke and we have put in a reinforcement.
Email me and i will send you some pics.
The holder for the heatexchanger broke, causing a damaged engine.
Will have to reinforce it to.

Otherwise the boat and engine goes well, doing 49 knots on top.

Here i norway we dont pay tax on the diesel so its quite economic.
Doing ribevents with RIB ROY from the forum, (7,5m Tornado with 250 Suzuki) we saw that it uses roughly the same amount of fuel on the same event.

Roy, we only fit Mercruiser diesel engines and a lot recently of the 320. Mostly 9 mtr ribs for Seasafari and to Scandinavia.
I have not heard of these problems but have asked the question and advised of your comments.
pls send me the pictures on info@parkerribs.com

Hi Andre
Will send some pictures to you in the evening.
How does your 9 meters perform with the diesels?
Roy

Cookee · 01 June 2006, 09:22

Roy - Once you've decided which is the best engine, then do the maths and work out how many hours you'l have to do to get your money back on a deisel, and then take a gamble on how long we'll have red deisel for!

we have 2 lines of 9 mtr ribs. The Baltic is really for twin installation but have fitted single Mercruiser 320 and max speed with single diesel is only 36 knots with 12 + 2 persons on board
The RS line is for single diesel installation and has a much deeper V hull
see photo (the rib is branded C-RIB 30 cos that is the name used in the Scandinavian market) during the tests on a lake in Poland the speed was 45 knots (Bravo 1 drive) with 5 persons and full fuel ie 440 ltr

Cookee:
The maths is realy simple her in Norway.
Diesel costs about 6,50 kr. pr liter an Gas costs 13,50 kr. pr liter.
With an average of 45 liters an hour or so i dont have to ride to many hours to pay the diferense between the diesel engine and an outboard.

Andre:
My boat does about 42 knots with 8 persons and 250 liter diesel.
Its very good in rough seas. but a bit lacy when its flat.
It performs very good in turns with no sliding.

You must be mistaken sir! Tornado say they've never sold a 9.5 metre!

This must be true, or they would have paid the agreed royalties to their designer.

searafting.no · 01 June 2006, 17:20

there is a valiant 7,5 m patrol here in Norway that is used as a charter boat, that have broken the engine mounts on the merc 4.2 l 2 or maybe 3 times only the first year in use.
