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.
