I would also like to know. I have an 03 PIII with 200 EFI. At the moment I have a 4-blade Trophy Plus 25P. Im not happy with the holeshot.

[revtro]

Ill try to get it in the water in the next day or two and get the data you are recommending to get. Hopefully thatll help lead to an answer. Thanks!

Heres what I have. 25p Trophy Plus. 200 MercEFI During the hole shot it topped out at 4220rpm. At 55mph it runs about 5200rpm and at 60 it runs about 5500rpm. The fastest Ive had the boat is 69mph on the GPS. I couldnt get it up to that speed the other day because of lake conditions, but with the numbers I have here, Id imagine topping out around 6,000rpm.So heres what I did that day:I changed the vent plugs from the large ones (which came on it from the dealer) to medium ones and guess what? It jumped right up on plane! In fact, it made such a dramatic difference, that Im wondering if one of those plastic rings that goes at the bottom of the prop between it and the shaft housing to prevent venting would help even more. I dont know what those are called or where to even look for one. A friend of mine had it on his Ranger. Any idea what thats called?

[revtro]

Great. Ill order one and give it a try. So for a 25p TrophyPlus on a Pantera 3 w/200 EFI, are those good numbers?

[revtro]

Yeah, all I can figure is that I was getting too much slip and therefore not enough tork to get it up on plane. Ive heard that can happen. Either way, when I went to smaller plugs, it got right on plane for me. I was surprised. Ill take it.

3 blade or 4 blade? Trade?

[revtro]

Im not in a huge hurry. I have a 3 blade from a friend that Im borrowing short term. I dont know anything about the High Five. But I think I probably want to stick with a 4 blade. Do you think Im right that a 4 blade will help a little with the top end rpms? Im still trying to figure this all out. Thanks!!!

BCB I need your opinion. As I stated above I tried an older Merc 23p 3 blade prop and was at 5800 rpm at 60mph. Previously I did 64 no problem and even hit 69 with a light load using the 25p Trophy. But the hole shot was horrible. In fact, I think it was such a load on the motor it was eventually gonna damage the engine. As you said “too much wheels” for that rig.Is a 4 blade 23p prop the answer for me? Im wondering if a 24p would give me a good hole shot but I cant see only 1 degree of pitch correcting the problems Ive been having with the 25p. The hole shot and midrange with the 23p 3 blade was awesome. Im thinking a slightly larger prop such as the Tempest or moving to a 4 blade Trophy may bring those top rpms down a little. Im having trouble getting anyone to let me try a prop first, so I want to make the most informed decision possible. Thanks again for your help. PS. Does anybody on this board run a PIII with a 200 EFI? If so, what prop is working for you? Help!~ please.

Ok, read the FAQ. I still have some questions. When I leave those valves that drain into the bilge open, they act as an overflow. When the livewells get too full, the water comes out those valves and into the bilge. So, then I closed them. Now when I fill the livewells and forget to turn the “freshwater in” off they overfill. They are not acting like they have overflows because the water fills all the way up to the top and overflows at the seam at the top of the livewell into the boat, bilge, etc. So now this makes me wonder if the livewell overflow is clogged?? However, it has done this since day 1, so I kind of doubt it. I’ll try to run water with a hose into the overflow and see where it drains if at all. Is there a plumbing diagram anywhere to help me with all this?

[revtro]

That’s what I’m doing. I’m using the Freshwater In pump to fill the livewells. But if I forget that I turned them on, the livewells overflow into the boat and bilge. Are you saying that the overflow can’t keep up with the Freshwater In pump?

[revtro]

Grr. I seem to forget to turn the freshwater in off every time. I get to fishing and forget that I’m filling. I wish the overflow could keep up when this happens. Oh well. I guess I need to tie a string to my finger or something.

[revtro]

Yeah, mine are so quiet that you can’t know they’re on unless you see the light on the switch. Easy to forget once you start fishing.

Amendment: I need to stick with a 24p. A friend of mine just hooked me up with a 23, but its too high rpms for my rig.

[revtro]

Amended again! I just bought a 24p, so I am just selling the 25p Trophy Plus for $275. Email me at tomouweleen@yahoo.com if interested. Thanks!Prop is in great shape and I have pics.

[revtro]

Prop is sold.
