What's the best 4 stroke 200hp ?

Diesel and 7 m, I can't make the figures add up, so what advise can all you petrol heads give me.
Looking to put approx 200 hp onto a 7 m, must be a 4 stroke. Is 200 too much............!

What consumption could I expect / hour.

Look forward to some banta to confuse me even more.

The cost of 2 stroke oil is a small price to pay for the exquiste performance of the Optimax engines.

Yamaha engines have an enviable reputation . from looking at the engines from nearly all of the manufacturers then Yamaha seem to be the best assembled/engineered

Suzuki are offering some attractive prices and margins to their dealers to break into the UK market, so the dealers are pushing them quite hard, they are a new range of engines so you may experience soom teething problems

Optimax

Thanks for the info.
What sort of consumption do these engines give .( I won't use the word economy).

wow, you serious.

from my own experience it is refreshingly economic, but I do like to see how far the throttle can travel. On my boat a 6.5 Scorpion I get around 35 LPH at around 50mph (opti 150 ) the oil burn is certainly higher than 60:1

I drive a Ribcraft 7.8 on charter and that returns around a litre per mile at 45mph with 4+ people up( this has a 200 Opti).

it's nice and choppy today so I am going out for a blast up to the Needles, I'll measure the performance and let you know when I come back.

re diesel/4/2 stroke and costs how many miles/hours per year do you expect to be using the boat for.

If i may be so bold as to qoute JAHNO from a thread he wrote yesterday, I believe his comments kind of add creedence to my views as he is out there working his boats all the time

' we have a 90hp merc 4 stroke on a 560 - that is spot on.

You need at least a 130 hp for a family cruising fun boat.
GraemeCooper has a 130 hp honda on a 620 which is a nice cruising boat, i have a 150hp optimax on the 620 now which is as economical as the 90hp and produce plenty of power when you need it.

The 620 handles a lot better with the wheight at the back, but the 560 is better with the wheight up front.

The suzuki 140 would be my ideal choice for family cruising, or possibly the 135 optimax. '

PeterL, I see you live in Pembrokeshire.... if you want to see and try to hear my 140 Suzuki I'm sure we can meet up if you want.

I'm frustrated since we couldn't launch today because there was nearly 1metre of waves crashing onto Neyland beach, which would have wrecked something during launch.... I was almost looking forward to inspecting the 4.5 metre swell at St Annes too

-Alex

I noticed to-day that the chandlrey attached to the Dry Boat Storage on the Camber Dock, Portsmouth was charging 25 per litre for Optimax oil and 17 per litre for Quicksilver 2T oil. I seem to remember paying 14 for 5 litres of QS oil.

I know the Optimax oil is expensive but 25/L
