Prop Advice Needed ?
Hello all,
My hole shot is terrible with more than just me in the boat. My setup is a 2004 Trophy 2052 with merc 4.3l carbed / thunderbolt igniton, alpha 1 gen2 running 1.62 gears with trim tabs. The boat is heavy at approximetly 5000lbs and under powered for the altitude about 6200ft. I'm currently running a 14.5 ptich 4 blade which is just about as low of pitch as I can find in a 4 blade for my application. At WOT with this set up I"m turning about 4300 rpm which is a bit low , and reaching a top speed of about 31-32 mph.I'd like to be right up against the rev limiter at approx 4850 so when I am loaded I'm running closer to spec. With the a full tank of fuel two large dogs and one small wife It took me a country mile to plane out last weekend and really worked the motor out. I'm going to be testing some different props this week, my fear is that with a three blade in the correct pitch say a 13 or 14 ( which is what the merc prop selector returns as possibilities ) is that I'll get the rpms but with a ton of prop slip. I'm really starting to think I may need to throw some high altitude gears at this thing to get me back into more commmon prop sizes. Has anybody had a similar expeirance, if so what was yor solution? Any thoughts our comments would be appreciated!
Thanks, Mike
