Ayuh Mate and thanx for the welcome and reply. I am supplying a photo for review. I have the boat on the trailer for some spring cleaning. I did run the boat last weekend and was wot @ 4500rpm and 58 mph with just me and a 1/8 tank of gas. That's GPS MPH by cell phone not the boat gauge. I have read a few other of your responses and see you have knowledge on the subject where I dont. I have seen other Pachangas running 63-65 mph off stock big blocks. This prop needs straightened out for a replacement if needed.
What prop pitch and diameter would you prefer to run 5-6 mph faster keeping the RPM around 45-4600? Any ideas? Stainless prop preferred. Thanks again
Ayuh,.... It'll take from a couple hundred to a several hundred more horsepower to do that,....
Just the fact that yer motor is held to 4500 rpms, says that's it's horsepower limit,....
'n with the Alpha drive, yer motor is already at the limit of horsepower the drive can take,....
Ya might try findin' other owners of boats like yer's, 'n see what they're runnin' for horsepower, 'n drives,...
Ya might try a 19" pitch to see if increasin' the rpms can increase yer speeds,....
Ya might try a cleaver style, 'n see if it'll free up the hull better than the chopper style ya got,....
A Clean bottom, 'n lightenin' the load will probably give ya the most new speed,...
Straightenin' or "Blue-printing" the bottom could also be worth lookin' at,...
Sorry I ain't more help, but yer expectations seem abit high,.....
