Custom 3 blade props. New carbs, crate 502's, after market exhaust and intakes. Nick that has my old boat changed carbs, intakes and heads. After that he went to blower motors running very low boost. The 28's do not like 4 blade props.

Oh, another thing I found that was super weird, is the boat had a gen V and gen VI 502 in it. I am sure that affected the way it ran because the gen V had tappet valve cam and the gen 6 was a roller motor with aftermarket heads. They match now….They are both roller motors with the aftermarket heads. That is the word I got from the engine builder. Again, I don’t remember what the name of the company was, but the marina putting the motors in gave me his contact info. The heads are supposed to be an upgrade from stock, but I honestly don’t think the heads will do much for the motors with the stock intake and cam.

I run 4 blades on mine and they do better then the 3 blades. After talking to Mark I am thinking about 5 blades. Mine wasn't rigged at the factory either. Mel Riggs did the rigging on mine. I think it may depend on weight and the bottom. Also drive depth. Just saying.

I bought mine from Texoma. Did some upgrades had it for 7 years or so then sold it to Nick. It is the one with the arrows. Nick did more upgrades heads, exhaust, cam, carbs and was running mid 80's. This year he did the blowers and redid the engines again. The three blades that came with the boat when Tex had it had did have some work done to them.

The boat with the arrows i owned when it had its original 454 mags..I ran it around on the deaware river mostly. That was around 2002. sold it i think in 04. If i reacll it ran aroung 67 with that power. It is a nice boat. My opinions is its one of the good ones.
