Hi Lee,

You could also consider glueing a pair of Opti 150's on the back of your Prosport. They are a very good and cost effective engine with confusingly good economy......anda lot of whoomph!

As your sea is fairly nasty it makes sense to have the contingency a dual setup could bring .

regards
Stuart

I found they had put the petrol up 3ppl to 43pl!!!

Outrageous !!!

If only ... !

Another thought, Lee: Do you know if the Channel Islands are likely to be sucked into the diesel price hikes that might be coming to the "mainland" in 2006?

If not and the boat is large enough, I guess it would be worth considering.

I had the good fortune to join Richard B on "Blue Ice" last weekend, when "Spirit of Portsmouth" returned. It was interesting to see how the 8.5 mtr boats handled the "chop" created by 30 or more RIBs cruising up the Solent. The 7.5s seemed to do pretty well too!

If an 8.5'ish boat is viable, I think it should allow you to put a more substantial diesel on the boat. Although this would obviously add to the overall weight, relative to a large petrol outboard, I imagine that you would get good performance from a 300HP+ and the weight would be well distributed, low down in the boat.

No doubt there are many people on RIBnet who could verify my comments, based on experience of their own boats.

Good luck with your choice!

Regards,

Chris.

300 HPDI

Just for info;

You can`t find any 300 HPDI with long shaft, only XL and UL shafts, wich means that you will need a bracket or install the engine very very high.
I think the 300 HPDI will be better as a doubble installation on a bigger rib than 7,8m.
An recomandation is to look at the 250 VMAX HPDI wich gives 274 hp and have a nicer design.
Good luck.
Regards
Petrov

Set Up

Lee

A nice boat set up if you dont want to go to over the top would be a 7.5 or 8.1 Mtr scorpion rib with the Yamaha 165 Turbo diesel, this would be very cheap to run and give you a reasonable turn of speed, of course if you wanted a bit more just drop the 245 Yam in.

ideally second hand is my idea, but you trying finding a decent, large diesel!! There are like rocking horse's dung!!!

And the budget was about 20k, which means most manufactures are offering 6.5 with diesel's about that price

Hi Janis,

I think what you say about the 300 HPDI is correct, but now the 300 HPDI Vmax is out and appears to be only available in a long-shaft (20") version. See the "Hotsheet" that can be selected from the link below

Exciting stuff !!!

Best wishes,

Chris.
