We do have some heated sibling rivalry discussions though

Can't do it in the US either. Now it's like $0.53.Blue you are wrong about the USPS and I have no dog in the fight. As bad as they maybe they are the gold standard in the world. No where else in this planet can you get a letter delivered 3000 miles for < 50 cents.
No, I'm not joking. I buy lots of stuff online and the USPS is significantly cheaper for most packages. I'm not talking about letters.You have to be joking???
Okay I am done with this thread
I've noticed that seems to be pretty normal around here. Threads going off the rails....A fuel price thread arguing about the cost of mailing a letter...
Its snowing and the boats are on the hard. Threads sway because there's nothing else to talk about.I've noticed that seems to be pretty normal around here. Threads going off the rails....
Actually, I don't trailer. That is why I have to pay the going rate on the lake, can't shop on the road. My whole point was if gas gets to $10/gal that might get my attention. Anything less and it isn't really a thought at all. $5/gallon has typically been the point where there is a noticeable drop off in boating traffic on our lake. So I like to take advantage of the reduced traffic.High,
Don’t worry about it. It’s a big country, as you say, where you live you must trailer cause slips expensive, up here on the Chesapeake they are relatively cheap. I would never trailer, you must, gas prices matter to you, don’t apologize, they don’t matter to my style boating. Different worlds, all good.
Why 89? I do the same with 87 and skip the snake oil, all good
Been in the game for a very long time and never noticed any of thatLittle bit lower combustion chamber temps , more importantly the ECM doesn't pull timing as much with 89 when it's sucking on 140° engine room air.
Using the 360 Marine at 1 oz per 20 gallons for regular use in 1 oz per 5 gallons for storage seem to do a lot of good for my outboards and pwc's over the years.
Notable difference in the rubber components in the carburetors after a 200 hour period
Interesting info. I'm no expert by any means, but I always thought (read) that higher octane burned hotter.
Surely, octane and knock are related. Proven by experience in cars AND boats.me neither, but as a guy who is a dyno tuner explained it to me the higher octane is more resistant to knocking and keeps temps a little cooler under severe load due to the flame front moving more slowly through the mixture upon ignition.
also, the higher the intake air temperature the more likely you are to have detonation (knocking). Even if an ecm is tuned for 87 it will pull timing if the knock sensor sees detonation. That hot bilge air isn’t the greatest for maximum performance
how much difference does it make? Probably not much but I’ve always stuck with the next octane over minimum for marine stuff since it’s pulling sustained heavy load. Maybe a waste, maybe not
