twin Yammies

Hey Gang,
Just had to tell how it is going up here in the frozen north of Canada.
Our 28ft aluminum hull rib has twin 150 hp Yamaha 4 cycle O/Bs and just plain
scoots.
It will top out at 5700RPM and 42.5 knots at 30 gallons per hour
I run it at 5,000 and do 34knots at 17 gallons per hour.
When we first got the boat I thought the fuel economy gauge was calibrated in Litres per hour and was thinking that 20 litres per hour was pretty nice and
pretty amazing how they could squeeze that much horsepower from that much fuel.
I'm OK with the gallons per hour since we are going so fast.

We are at 51* 20N and 128*05W near Bella Bella British Columbia Canada
catching some mighty big Chinook salmon (63lbs.)and big halibuts(99lbs.)
a great summer job

best wishes
hank

Good question about imperial or us gallons -I'll have to check into that

both engines run off one tank and through the one fuel flow sender

props are in the water but that is about the only part that is

"see" you all in September

Dare I ask what the hell are "scoots"???

People often don't realise just how far North Britain is - even Swansea which is pretty southerly in the UK is further North than you are. We don't get the same weather though - just plenty of glae force winds and rain rain rain!!!

Sounds like a great boat - why not post some pics???

Thank god for the Gulf stream otherwise we'd be struggling with plenty of snow, no public transport and a road network in chaos every winter. Or perhaps we'd evolve to learn to cope with these things!!!

Two out of three ain't bad. Some snow would be nice though!

Canada uses imperial gallons i.e. 4.45 litres not them horrible US gallons. Mind you, what Hank's fuel flow equipment is calibrated in is the point of interest. 30 galls per hour (imperial) is 133 litres per hour ! I'm assuming that has to be for two engines so 65-66 lph for an engine at flat out seems in the right ballpark. I'm guessing these are 'old tech' 2 strokes not HPDI's?

As for being in the Great White 'North', my bit of it is actually on the same latitude as Paris (e.g. south of London). Its the Atlantic Ocean that insulates us from extremes of temperature and gives us a ready supply of moisture (rain, fog and snow).
