Stock Prop

[spdracr39]

Does anyone know what the stock prop is on the boat in my signature? The one thats on it works well and I want a new one for a spare but it is not marked
I know it might not be the stock one but I'm looking for a baseline.

Re: Stock Prop

There really isn't a stock prop they are usually listed as best speed best load/skiing
etc.Did you look under the prop nut for some numbers?Also is it stainless or aluminum. Al. is not magnetic.
If you can get us the prop numbers and your present max rpm and speed.
If no numbers on prop a prop shop can measure it for you.

Re: Stock Prop

Do I need a special wrench to take the prop off? The boat dry weighs I think 3300 lbs with three adults, full of fuel, and gear I figure we were at 4500 lbs.
WOT was 4600 rpms and 48 mph GPS. My current prop is 3 blade aluminum I was thinking of getting a stainless replacement ( just cause they are pretty ). We don't ski or board just cruise. I am happy with the top speed of around 50. If I go stainless should it be the same pitch, diameter, and number of blades? I suppose my main goal is good fuel mileage without sacrificing top speed.

Ayuh,... Only if you consider an 1, 1/16" wrench Special....

That'll work....

Re: Stock Prop

It sure appears your setup is pretty good.Your rated max rpm is on a label on the motor.It appears there are 3 versions of the 5.0 2 are 4800 one is 5,000.
If yours is 5,000 you could drop an inch or so and gain some hole shot.
A stainless prop will cost double or triple of your al prop.In the event of damage to the ss it will cost more to repair.When changing material
results are harder to predict.SS usually will result in across the board improvement
but could vary from a few tenths to a few mph.As far as fuel use generally hard to tell any difference without a flow meter.your best cruise could be anywhere from
just on plane to several 100 rpm more.
