any advice/experience of the 7.5m prosports would be very much appreciated and also of the 299 hpdi yam engines- reliability/noise/ecxonomy etc.

thanks ribnet as ever!

sorry! I meant the 200hp hpdi !!

I have seen more and more of these around lately (prosport) and they seem to be very popular.

As for the Yam engine I have been told by someone who has one that they are very good.

Sorry cant give you actual experience but hope this helps.

I have a Yam 200 HPDI on Blue Ice. Have only run it for about 50 hrs between buying the boat and putting my back out but knew the boat and engine in its previous ownership. V impressed as it is a smooth and quiet unit. Fuel economy seems to be reasonable at the litre per mile level at cruising speed (30-35kts). It is significantly quieter than the Optimax I used to run. They are more expensive though.

HTH,
Alan.

PS. Cant give any advice about Prosport RIBS as never seen one in the flesh.

I use a 200HPDI almost on a daily basis for training courses. It is fitted to a 7.2m Ribeye and returns approx 6.6gph @ 25knots as shown on the fuel computer.
Quite happy ticking over for most of the day as well without any smoke etc. Gives instant power responce when needed in rough weather. Very Quiet motor compaired to some other makes I have used. Yamaha Dealer Servicing also reasonable for this size motor.
Overall V Happy

The Yam is a great engine!

I believe the hull is based on a BWM which are well known for seaworthiness.

I own three engines

a Mariner Optimax 150, A Honda 130 and a Yamaha BETOL 70

whilst the Optimax is my favourite engine (because it has the most grunt and is on the fastest boat) the Yamaha is undoubtedly built to the highest standards. I would have no problem recommending any of these makes but my preference for the next engine will be an HPDI.


There is a diffrence between Optimax technology and HPDI and FICHT, but essentially they all purport to do the same thing. ( cat is now entering pigeon loft) which is to use technology to minimise Fuel burn, most of this techology is based around increasing the injector pressure ( I think) From my experience of the Opti this seems to work as the Opti is quite economic. I believe that the Yamah's are more so

Stick to two strokes cos you can't beat the smell or the noise and more importantly the snap of Power.

All my boats are used regularly and I find the Yamaha to be the most reliable
