New boat?

I am thinking of selling my 6.5m Ribtec early next year with the idea to get somthing a little more conservative . The only problem is I don't know which RIB to get. I am fairly certain on a 1.7tdi engine and I don't want to go much bigger than 7m.

I have looked at Humbers 6.3m Ocean pro which has good performance figures: with 8/10 divers on board 35 Knots (its main use will be diving), light load 40 Knots each with 23" props. And burning apparently 2 an hour diesel!!

Prosport appear to be good but not as good on the performance (if Humbers figures can be believed).

I don't want to fly around the place like a nutter but 30-35 Knots with divers on board would be preffered. Any other ideas on RIBs that would do the trick. I have a budget of around k20. I may also consider a boat with an Opti .

Also does having the engine box in the boat take up alot of space? or can I use the cover for bottle storage?

9m is a bit large to tow around the place

I don't believe those figures quoted for the Humber. I reckon that the top speed is more likely to be no more than 35 knots, and much less with ten divers on board!

Are you happy with your RIB apart from the fuel bill? Have you thought about just re-engining itwith something a bit less thirsty? A 150 Optimax would give you good performance and use a whole load less petrol than your old 200.

You'd still be spending a lot more on fuel than with a diesel, but it's probably worth working out the sums . . .

tue, have a word with Pro Sport and try to get like for like figures for comparison. Are the Humber figures in lab conditions or real useage conditions? For marketing purposes they'll have selected the best sea state and optimum loading for the tests, as I'm sure they all do.

I have considered it. We have a 150 Ficht at work but I don't like them much and I'd need to sell my 200 first to get get some cash in for the Opti.

Know anyone who wants a 1999 200hp Mariner with about 50hrs on it

Apparently they are done using owners reports in conjuction with Mercruiser.

So they looked at the owners reports, looked at the manufacturers reports and made up some figures completly different that looked good

1.7 ltr Merc

We are getting 35 kts with full fuel and 3 persons on board thats with a 23 pitch prop pulling 4200rpm,

we could probably swing a 25 pitch to increase the top end but I have to agree 40 kts is a long way off???

Drop me an email if you want some more info also i will send you some pics

Welcome to the Mercruiser 1.7L TDI fan club

I see that this engine is begining to be very popular and so it should.

We have a new member Tero Johansson from Finland and his profile says he has a Revenger 7 mtr with the Mercruiser 1.7 L TDI

Tero, welcome to the Forum I hope you enjoy it.
What can you tell us of the performance of your Revenger with this engine ie, top speed, fuel consumption, ect

Andre

PS. Jason's latest figures are now more realistic
