Motor: Tohatsu 30 4-stroke
Load: 330 lb of people + 5 gal fuel + gear (no TM) + size 24 rear mounted battery
Stock aluminum prop 9.9 x 13
* Top Speed 26-27
* Excessive blowout/cavitation on smallest of turn, trim, reverse, wholeshot. Almost unusable.
* Frequent slips, cruising straight, on plane at any speed
* Weak holeshot
Powertech SS 3 blade SRA3R11P
* Top Speed 27-28
* Good bite forward and reverse
* Cavitation greatly improved, blowout issues 95% resolved
* Holeshot greatly improved
* Trimability now exists
* Compared to stock prop boat has the feel/response like I gained 10-15HP
Wish I had a tach to provide RPM data. The performance difference of a prop with some rake and cup is night and day.
