20MPG in a boat - Wow! Pretty happy with props I am testing as my daily runners. The 16,000 lb 42 footer acts like a 30 footer with them - gets on...
Thanks CDog - getting there. Replacing Trim Pump today which will make big difference I think in terms of finding best economy cruise speed and...
Took a few 10 mile runs on snotty seas this weekend (3-4 footers) - got 30mph nice cruise at 3900-4000 rpm at 17.5gph per motor (.857...
I can run on one motor but only have power steering on one motor at the moment. I have pump on each but only have one hooked up....could look into...
3.1/motor so 6.2gph or 1 mile/gal
picked up some high rake 16.5x17 3 blade rolla props. Boat now gets on plane easily, can cruise at 3800 at 24mph (one adult, 200g fuel, light...
Appreciate the inputs. Because the surface drives can be lowered and are about 3 feet long, the props can run in fairly clean water behind the...
Will do some trial and error soon - have a set of 16x26 3 blade clevers. Boat wont plan with them but interested to see what it does to 800, 1000,...
appreciate the suggestions.
Vessel has Arneson ASD8 surface drives. Shafts are 19-spline 1.25 inch. The availability of props in the size range I need with 19-splines are few...
Thanks Guys
800 rpm = 5.29 slack tide on ICWW 1000rpm = 7.00 mph 3.2gph per motor 2000rpm =9.01mph Does this help with analysis?
Actually it is. My friend has the same boat with but CAT Diesels (ie much heavier than my gassers) and his weighs in at 17,000. His has been...
YES The motors are Mercury 496 EFIs and I have Vesselview which measures real-time fuel consumption in Gallons/hour. At 1,000 rpm with both motors...
Yes
The drives have about a 20-degree adjustment up and down. Sitting, the props can be as close as a foot from the serface.....so fully emerged. On...
Great comments - thanks! Motors are Mercury 496 EFI inboards - they are supposed to consume 1.3 gph at 800 rpm (each) or 2.6 gph@1,000 rm each -...
agree with the above - seems too light weight to handle HP
Does an adaptor exist to mount traditional "keyed" props on a 19-spline 1.25 shaft? Google let me down so thinking "no" Anyone know better?
As I get older I find I rarely go fast in my go-fast cruiser. Some will say "sell it and buy a trawler" which is possible but I like my boat....
