It's a flag. It's required when travelling on road (trailer). I just didn't take it off when I got home and flushed outboard.

The 2 stroke was using 13-1/2 X 15 Pitch S/S. The four stroke has a 13-1/4 X 17 Pitch S/S

Thanks for your comment

Thanks for your comment. I do soooooo much more tolling now I have the 4S

What does it hates trolling mean? What does it do?

Hi, the prop is 13-1/2 X 17". Probably could be a tad less pitch with max RPM being 5800

@@ShortFlic thanks mate. Have just repowered from 140v4 yamaha to the f130. Still yet to water test but trying the 16" for max rpm.

Diesel? or Petrol 4 stroke. My brother had a 30ETEC which did 6km per litre of fuel (at 30km/hour). This equates to 5 litres per hour. That's the best I've come across in petrol..

Thanks for your comments. Yeah, I think the F130 was something Asia Pacific? or Australia / NZ thing. Maybe we are the Ginny pigs :). Both are great motors

Yeah, I found some seriously technical documents online but it makes sense with heavy Stainless props verses and 4 stroke power cycles. I purposely avoid that rpm. I would suggest any extra vibration or load cycles is not good for engine longevity..

My motor was 130BETOX 169kg.

🤮

Thanks for your comment, appreciate the Yammie / Merc rivalry. Merc don't do a 130hp...yet. 150hp too heavy too

Thanks for your comment. Probably something to do with boats and outboards being sooooo much cheaper in the States :) . Boat is rated to a 150hp but an extra 50kg is a lot to consider going from 130 to 150 including a six cyclinder (verses four) and quite high centre of gravity. The balance is perfect

Yeah agree. Punchy. The four has opened up a bit, now doing 120hours. It has a nice mid-range whine (like the old mercruiser sterndrives). Miss the 2 stroke, not the fuel bill or smoke.

Thanks for your question - sorry for the late reply. The boat hull is 860kgs

Yeah, those 60 degree cylinder angle (low head design) were manufactured by many outboard makers with commercial fisherman in mind, especially netting with low obstruction over back of boat

After starting to do my own, it really isn't a massive issue or cost, even running full 5W - 30 Synthetic oil. Cost from dealer is $750. Cost at home is $120...Bit like a small 4 cylinder car

Hi, Thanks for your question. I installed a Lowrance Electronic Fuel Flow Sensor (SKU: 000-11517-001). This connects to Lowrance HDS7

Yeah, could do with a minor prop change although its done 100 hours now and its opened up a bit. Can get about 5900rpm

Hi, thanks for your comment. Not sure what you mean about error? At WOT the 2 stroke is only doing 0.82km/l (820mtrs) and the four stroke at about same revs is doing 1.47km/l. Based on my recollection, when the 2 stroke is doing 1.21km/l , the revs would be about 5,000rpm (probably 62km/hr). The four at this rpm would be doing about 2.4km/l and maybe 55km/hr. Hope this make sense

Thanks for your comment. I asked the Yamaha Service guy about this (as I've just completed my 100 hours). He said the four is happy to sit in the top end rpms. In the past 2 strokes with few moving parts were definitely considered more reliable however fours have come a long way. Near flat out at 5500rpm is nothing for a 1.6L four cylinder vehicle engine....

Absolute nonsense.

Cummins oil injected dry sump OP 2 stroke

2 stroke motors just dont die and yes I love the smell of 2 stroke 🤣🤣🤣

Top seed is about 42km/h

As opposed to valves And timing chains? Four stroke still have bearing that blow Up too

I'm sure some new outboards have variable valve timing to improve low end torque and high end power. Having said that, more moving parts...

@@vlogcity1111 Most four stroke engines have a one piece crankshaft and use slipper white metal bearings which are oil pressure fed. The reliability of slipper bearing is very high, they always last the life of the engine. With tens of millions of modern four stroke engines in service slipper bearing failure is less likely than the odds to winning a national lottery.

@@AquaMarine1000 I agree with the mechanical aspect. There’s a reason you didn’t address valves because that’s a huge weak point. Most high quality precision bearings will last the life of an engine, valves however can go pop at anytime without notice. Usually a con rod or crankshaft bearing will give you a noise when it starts to go, whereas valves can shatter or melt without and pre warning. Yes that can happen on a two stroke but not as frequently.

@@vlogcity1111 Some two strokes like the Detroit diesel do have exhaust valves. No engine is unbreakable especially if it is not maintained or operated beyond it design parameters. Two stroke engine production has now been relegated to history. Cheers
