200 Yammy 2 Stroke

Mon, 2013-08-05 12:30

 Dont know if this helps or not but....

I have a 200 that is also a v6. it has plenty of power to push  my 6.5m walkaround fibreglass. It also drags skiiers and tubes out very easily.

Like all two strokes it does use about twice as much fuel as a fourstroke. Again it depends how I use it. If I stick on about 4200 RPM I am doing about 28 knots but if I wind it out to 5800rpm I am doing about 38 knots. Only 10 knots differfence in speed but heaps of difference in fuel burn, the extra revs will burn at least three times as much.

I am currently playing with different pitch props to get the best of all worlds.

i have a 175 HPDI 2 stroke

Mon, 2013-08-05 12:42

i have a 175 HPDI 2 stroke Yammy that i dont think uses up to much fuel, but i havent tried out any other motor.

just an example, i went out for a full days fishing friday, moving around from spot to spot did approx 70km + in the day i used about half a tank which would be about 75 lites of fuel.

not sure how that compares to a 4 stroke.

 We did 110km last Friday and I burnt 123L with a 225hp Honda 4stroke on a 7.5m glass boat.

I use about 21-23L form Hillarys to Thomson Bay

I have a 175 Saltwater Series

Mon, 2013-08-05 20:36

I have a 175 Saltwater Series II on a 6.55 fibreglass.
Plenty of power but yes, as everyone has mentioned, they can be thirsty when opening them up.

I have a 250L fuel tank and if I pushed my luck I'd get three return trips to rotto. So on average about 80L round trip.

My problem is that I love the opportunity to wind it up (who doesnt like the sound of a 2-stroke at WOT) :)

Super reliable, easy on the oil and very cheap to service. Love mine.

Well I always leave from

Tue, 2013-08-06 21:42

Well I always leave from Matilda Bay, go down river to Fremantle and out direct to Rotto. That's about 20nM each way according to my calcs.

All the feedback I have ever heard on these outboards has been that theyre rock solid. That's really all that counts for me.

If you don’t like a loud motor you have to spend the $$$ and go four strokes
