I have ordered a pro 19 p prop and going to stick it on this weekend ,Vented I cannot find easily have a new belt coming as well. The boat has recorded 27 hrs on it.so it is as close to factory as can be . Thanks for the help more on Friday.......
fingers crossed.You may want to check what the belt drives.The old Ford Escorts belt would squeal if the pump was failing.
Obviously nothing to do with an outboard just have to wonder at 27 hrs. why is it squealing.Just stretched?
Well guys, bought the prop Yamaha 19p pro and got 53gps MPH definatly the prop made the difference!!
does anyone recommend ethanol free gasoline on 4 strokes?
"Prop calculator says 6500 rpm. to get 53 mph. ??"
No need to recheck - you are absolutely correct as you helped us with a similar application 2 years ago.
The gear ratio is 2.15:1 and at 6,100 rpm's and a very small slip on our boat we saw about 48 mph max.
That was on a very light RIB on a perfect day.
