What's the best 4 stroke 200hp ?

PeterL · 02 November 2003, 10:18

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.

Optimax, oh sorry I thought you said what's the best 200 hp engine

Jono Garton · 02 November 2003, 11:43

the new 200hp v6 four stroke suzuki!!!

optimax's are ok if you want to own shares in Quicksilver Oil

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

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

thewavehumper · 02 November 2003, 13:52

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

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

Jono Garton · 02 November 2003, 17:21

try buying a 10 gall drum or buying some of wave humpers oil

thewavehumper · 02 November 2003, 18:25

Thanks Jahno, that's a jolly good idea. Richard B keep out of this!

I can do 20 litres for 80 kwid as I bought a 45 gallon drum and it cost me 799 poonds

Thanks very much for asking that question, I've just come back from having a real good time out in the Solent, it was quite bumpy and dark out there and very invigorating. to be honest I dn't have the bottle/stupidity to get up to 6000 revs but I'll do that in the daylight next week.

at 4000 revs fuel burn was 28.3 LPH ( about 35mph)
at 5000 revs fuel burn was 45.5 lph (about 50 mph)

I#ll get it up to 50 knots in the daylight and come back to you, Jackeen dya fancy coming out on the test run!

As I was out in the rougher stuff, with the wind howling, the waves crashing and the sharks a circling, I was very pleased that I could gauge the engine revs from the varying pitch of the beutiful sound eminating from my outboard. You can't do this witha n engine youcan't hear. When it's choppy you don't want to be looking at your instruments to see what your engines up to

Doesn't that put us back to square one on the Opti v 2-stroke thread

Good point about listening to the engine tho' - as this is a bit topical:

Stu i don't want to piss on your fire mate but i only paid £19 for a 5li can, of which i put two into my tank 'tother day old boy.

Now which one of us has got our knickers in a twist?

thewavehumper · 02 November 2003, 22:05

hi Daniel

I think you'd be the one with the twisted underwear, probably that's not all it is after yesterday

They don't do 5 litre cans, I think you will find they are 4 litres (1 US gallon as opposed to an imperial gallon). Even so for a 4 litre that's a good deal. It's 22.75 round these here parts. I was expecting a better price for such a large quantity and if it was available I'd have preferred 20 gallons

It doesn't matter if I dont sell any on as it's still there when I want it, but it would help me offset the large outlay. It is nice though having it to hand as opposed to waiting for a chandlers to
open on a Sunday morning.

Cheers
Stuart

Just checked my bill. The £38 is quite insignigficant on the whole scale of things but is the price nevertheless.

It is possiable this is a special price given the amount of £'s i've just spent with the people.

You are right about the 4li thing though, that'll explain why the smartcraft gague said i had 8.1li of oil when i filled it up, and i thought it needed callibrating
