Hi, I have a 6,10m Center Console with Twin Honda BF75 EFI:s.
I am currently running Solas Rubex 3x13x19 at approx. 5800 rpm, 38 knots and the antiventilation plates is about 15-20 mm over the bottom line.
I raised the engines 1 more hole ( 20 mm ) before putting the boat away for the winter and was planning to testride next spring to find out what props/propsize to run.
Now I have the opportunity to buy Michigan Apollo propellers really cheap ( at least for in Sweden) and I dont know what size to buy?
I think I will gain about 200 rpm for raising the engines 1 hole and loose about 200 rpm when running a cupped steel propeller.
If my calculations are right I will stay with 3x13x19 size propellers.
I Think the 3x13x21 props will be too much or?
What does the propgurus have to say about it, any ideas?
Thanks,
Sven B aka Pikeman
