I think anyone who bothers to research and try props will make a decent compromise and get far superior performance to one who uses the first suggestion for their boat. I don't think the Eco is magic based on what I have read. IMO
If the price is no different then certainly try it. Benchmarking it against similar props on the same boat would be useful.
Also lakes and oceans aren't the same. 1 day in 10 I can use a F100 at WOT for any distance at all without getting airborne in buzzards bay (the Altlantic).
A heavier motor is a faster trip to the bottom, though. 
Edit: that merc isn't bad at 390 lb for 200 hp, though!
But I can see how a high altitude lake might be different. But if it's that smooth, I wonder about a Seacraft being the right hull for the application? |
Stretcher ... I could have been more specific. I spend part of my time on the lake here. The other Part on the Columbia River (Averages 30mph Winds Every Day with 2' to 4' Wind Chop) and another part on the Pacific Ocean.
I opted for the 20' because of Trailerability and the Legendary Ride on Rough Stuff.
I know we cant have everything but on this Side of the Country We have to do things a little different than you permanent Coasties.
SEACRAFT = PERFECT Hull for my Application. The 200 Merc weighs 20 lbs more than the Johnnyrude V-4 at 368 lbs. Looking for the Best All Around Prop and then will continue to test out for the Perfect Set Up.
Thanks for the Input.

I am going to swap out the 225 out for this 200 as soon as it is back in one piece and do some prop testing soon. I have a 23 foot proline the 225 is going on. I will run threw some different props and I did pick up an Enertia off ebay so there may be some info on that soon also. The 200 I have just got picked up at Tommy Dunn's shop so it may be faster than the 225 and lighter indeed. For those who don't know tommy he holds some records in the outboard drag racing seen. One of the best merc outboard builders on the east coast if not country. He builds these little 2.5's to over 350 hp. My motor is nothing major like most of his builds or like the pair going on the 27, but lightly modded at the least. The 2.5 merc is a good motha, one of my favorites. Good luck with yours, post up some numbers when you get it going.

Frizz, Now i am Jealous... That 200 You have is going to be Bad to the Bone for sure. If u get a chance to drop that Enertia on please post. No matter what i try i can't get my engine high enough. I am installing a 4" set back jack plate today. I am in the bottom Hole Now and still at least 1" too Deep on the AV Plate.
Thanks to you i went with the 200 and i am Glad i did. It still screams now with the AV spraying water like a Fire Hose. I will have some more data over this week. I think i saw somewhere that Bigshrimpin tried the enertia but i could not find that post but it was on a Master Angler.
The balance CG with the 200 is Perfect. Self Bailing on the 74' Tsunami. I have moved both Batteries to the Front and moved the 50 Gallon Gas tank up 8". I am waiting now to find out if i can Drop an 80 Gallon Tank In and still move it forward.
Looking for a Powertech 17p now. and will re-run the mirage and high 5 when i get the jack plate on today.
Keep me posted on that new 2.5 Dragon you got.
