So, I just finished a 1970 Las Vegas stardust. It's a 20' bow rider tri hull. It has a 120 mercruiser. Not sure if it's a 2.5 or a 3.0 (my guess from reading on here is 2.5...I'm probably wrong).
At WOT with 2 adults and 3 kids with a days worth of drinks and food in a cooler, it will turn 3500-3900 rpms at between 30 and 35 mph (barely 35). I can't read the numbers on the current prop to be able to give any numbers off of it.
My questions are:
1) is this the right RPM range?
2) is a new SS prop going to be worth the cost?
3) what prop family (mercruiser vengeance, fury,laser,ect) should I be looking for, and what pitch/diameter should I start testing at?
