Anybody got an awesome price on a 60 hp yet? I have got a 2007 yammie 60/4 stroke and paid $7500 for it.
Hi Dean. No it was normal 60hp. I worked out that the 60hp had a heavier gearcase which reduced top speed in normal boats. One of my customers put me on to a guy at bayside marine. They were very helpful but unfortunately now gone. The Aussie dollar has dipped and climbed back alot since I bought mine.
3.7 klm / litre but at what speed i reckon a tanker would go close to overtaking you.
i brought the new 50 hp honda when it came out fuel injected with blast.a fart would create more thrust than it would ever produce . other than that i love it though a poor load carrier . personally going back from four cyclinders to three can only mean less fuel burnt when the piston is closet to tdc so as a work force i would say yammy still by a edge. both are still straight block engines i presume correct me if i am wrong.
22 knots is fine, if you can sit on that in most conditions it's all you need offshore ! I reckon there might be only 3 or 4 days a year that i wish i had more speed and i reckon there is about 10 trips a year when my crew are glad i dont
I pretty much live on 23-24 knots( 4700-4800rpm) what ever's going on with the sea and i do slow down abit on dark nights as there are just to many whales around atm!

Ps those oil tankers can get along, most seem to move at between 15 and 19 knots Berge Ichiban Tanking about large sailing vehicles we should definitely notice Berge Ichiban. The oil tanker has overall length of 322.95 meters and beam of 60.00 meters. The depth of the board if 29.55 meters and the draft of the VLCC is 18.65 meters, while the ship is fully loaded. The deadweight of Berge Ichiban is 298,552 metric tons and the gross tonnage is 159,397 gross tons. The very large crude carrier has main engine MAN B&W 7S80MC (Mark VI) with total power of 25,490 kW at 79 rpm. The service speed of the ship is 16.00 knots, while the maximum one is 17.1 knots. Ships from the class of Berge Ichiban usually have lower speed and they are clumsier, but this crude oil carrier was designed with high speed with low fuel consumption. The cargo ship was built on February 2000 in the ship-yard Hitachi Zosen (now known as Universal Shipbuilding Corporation. The cargo ship was built for Bergesen D. Y. ASA, which is one of the largest ship-owners of the world. The ship is double hull cargo vessel created according to latest requirements of MARPOL73/78 and IMO. The ship is created with increased protection for marine pollutions, in case of grounding...

Alcohol doesn't agree with me, but i sure do enjoy the argument!!!
I do like the 25409 kw at 79 rpm!!!

Dicko,
Can you PM me where I can buy these aftermarket ECU's I have a sh!t load of suzi,merc and yamy 4 stroke owner wishing to buy one
Honda is basically pushing the envelope on Air fuel ratio and ignition timing in conjunction with air intake designs to maximize torque and acceleration when called for. There are strict setup guidelines to enable this to happen (ozbee this could be an issue for yours) Due to CARB and EPA regulations blast can only come into effect when WOT is asked for (hence if cable adjustment is not setup to acheive wot blast will not operate) as thye air fuel ratio is pushed towards 11:1 it pushes the enviromental conditions.. at all other times when not at WOT the engine runs on lean burn technology.
Hope that helps those than need it

It's not a secret. There are dozens of aftermarket ECU's around.
Why are they wishing to buy new ECU's ?
The old saying of racing improves the breed rings true. The aftermarket companies & factories develop this sort of gear for racing then years later the flow on effects come down to the consumer.
Outboards aren't the place to be trying out "new" ideas. (well, some do), but the japanese are pretty conservative. If anything, the technonolgy in most japanese 4 stroke outboards, (Like EFI & Honda's V-tech) was developed 10 and 20 yrs ago in car & bike racing. What works they keep, what doesn't they throw out.
4 stroke outboards are just derivatives of car & bike engines they've designed & learnt from over the years, just tipped on their end and a leg bolted to them. They haven't reinvented the wheel... or propellor....so to speak.
For the most part, no one wants to piss around with their outboard for fear of upsetting the reliability, and fair enough. Though if one really wanted to, with a bit of thought with regard to compatibility of sensors etc, any adjustable aftermarket ECU could be made to work on just about any EFI outboard. (Remembering they're just a normal 4 stroke motor like any car or bike).
Some companies even offer an ecu designed to plug in as a direct replacement for the factory ecu, using all the original factory sensors .....which thankfully takes most of the brain work out of it. These are mainly for common vehicle applications, wrx's. GTR's, Evo's etc. The GMH & Ford stuff seems easier to use an aftermarket program & rewrite the existing ecu.
I can't see outboards being on the simple 'plug in' list for a while. You'd have to adapt one yourself. But you never know. If there's a market for them, they'll preconfigure them to suit. They may also be an option in yrs to come when the factory stuff is out of warranty and too difficult/costly to repair or replace, or even when people want to modify their 4 strokes to get an edge in boat or ski racing.
If you have people now wanting to replace their factory ECU's, it would be worth tinkering with one of these. All come with the relevant software.
Motec, is one of the major players in the racing world, like most it's infinitely adjustable.

I see they've now got a plug & play kit for the yamaha PWC's, with seadoo & kawasaki to follow besides the regular vehicles
Haltech offer one that besides all the other parameters, you can adjust hondas V-tech valve timing as well
http://http://www.haltech.com/index....=105&Itemid=20
This one from Vipec is a dedicated marine unit
http://www.vi-pec.com/page_files/marineECU.html
It also has knock control to adjust timing & AFR's, similar to what Honda is promoting.
Of course this is all about relative economy. Whatever newtech outboard motor fuel consumption figures are quoted it doesn't alter the fact that this form of transport (small planing boats) has appalling fuel efficiency (and emission production) for load carried over distance traveled.
Even the best of figures would leave those outside boating circles scratching their heads thinking how anyone could get excited about 2 or 3km/litre - 50 or 33l/100km. Although to us the advances made in outboard technology has potentially more than halved fuel consumption and bills, I don't think that outboards on planing boats should ever be called 'economical' even if they do have BLAST with an 11:1 air fuel ratio!
Cheers
yes i see your point , but who has time to waste with having a job through the week ,and trying to get where ur going at 6 knots via a small diesel shaft driven tub that sucks 2ltrs per 10 kms travelled??? not me im afraid...and id be guessing, most of the working population...
I too look forward to the day that outboard technology can compare to cars at 8ltrs per 100kms.......hmmmmm.... that sounds sweet
