Here is my last post on this issue. I went to boat and checked prop specs, I have two props a 2 blade
and an installed 3 blade
both with 16LH10 stamped on them. I used a propcal .xl program and with my 1.86:1 gear
box I get for a 2 blade
16x11, for a 3 blade
15x11 so prop size is correct. I cannot go with the run 1 hour fill run another hour at different RPM
as this will take too long, and, I do not have good access to day tank fill each time and how "full is full" hence the smaller Quantity of fuel
. I did the GPH calculation and came up with 0.28 at 1600 and 0.55 at 2000 and at recomended max of 2400 (manual specs 85LBS at 2400) I suspect this is max tourque output, I calcluate 0.94gph these look good but will check in spring.
Thanks for all your interest in this issue.
