Why are you wanting a new prop? More speed, better hole shot, ect,

I have a tracker V175 Combo with a 90 Optimax motor. (2012 boat, 2011 motor)

The boat came with an aluminum black max prop (19p) and while ok, it would blow out fairly easily on turns and while ok, was not great coming up on plane. With my boat would hit about 38mph at 5200RPM.

I have replaced it with a 17p Spitfire (4-blade) prop it now hits 35-36mph at 5600rpm, but comes on plane much faster and holds really well in turns.

I typically cruise at 4000 RPM (around 20-22mph) and am very happy with the change. (the spitfire also works great for towing tubes when needed). It was not an expensive change over and was well worth it in my situation.

(BTW - I had a hydrofoil on for both props)
