I have a GP marine stinger ss which needs a prop. Can anyone recomend an upgrade or even give me the spec on the stock prop. This boat is no longer available and parts are next to impossible to get.

Isn't that the one with two in-line 600 motors?

Please put some pics here to confirm.

If it is, you'll get away with a 38-42mm prop, depending on the pitch.

Yes it is the boat with the inline elec. my son broke the prop last year and I don't have the manual, so I'm trying to find out lft or rt prop, size? and is their a better faster choice.

Is the prop a threaded one?
Or does it slide on the shaft and is held with a drive dog (notch in the prop)?

What's the propshaft diameter?

Does the prop sit behind the boat (= surface drive, take a Hydro-prop), or under it (submerged drive, take a submerged prop)?

For both systems there are a lot of props available, if you can get them, go for the Graupner props, cheap and stiff.
