Motors Done finally

[eggsuckindog]

so you are still using the same 2.5L block as before? how much power should it be making now?? what brand pistons did you use? i may have to do this to my new 3L.

Yes the same 2.5 block, the 200 XRi was best I have heard a cheater motor for the bass boat crowd, as it came in 20" and is supposed to produce 220/230. A liitle bit of port timing and some fuel mapping in the ECU can find 20 or 30 pretty easy, I know it doesn't like running under 3400 RPM, you can hear it perk up and as Doodle Bug says they like to be fed. Actually that becomes tough sometimes in saltwater as its usually rougher but it appears this prop will smooth that out some but you still hear it wants 3400 and that can be that porting and fuel mapping.

Simialr to the Etec's the 250HO and 300 - both make simialr HP but the HO is for light hulls and would not be nearly as smooth as a 300 on a larger boat, its the power band thats dialed in the motor.

We bought everything from Pro Marine in Bradenton, they are cast pistons not forged - those are about $40 apiece more and according to most not really needed. I would check on shipping costs for the block, I really think between the the 2 of them I could get you a decent deal - getting the PH off is your issue and mine was not easy - took heat and stuff so it can be tricky so be careful who you would chose - but there is a 40% markup on parts so most times its 3500 for a rebuild.

Had it today and froze our ass'es off but got 3 hrs on it - super strong, the new Stilleto prop gave me 3 mph at 3400 25-28. Lifted the bow and the whole boat higher on the chines and it rode completely different. I came back across theb bay with 15kt following wind at 30 and Susan was laying on the bow box to get out of the wind and nothing bounced - amazing in comparison. So Stilletto props also work good, will give more numbers as I get it higher in RPM - today @ 3400 = 28.4 - 3600= 30+ 3800 was 32+ but wasn't there long, 5700 should be fun.
You just can't imagine what a difference a prop can make - HP does it too by the way which is why I advocate it, lets the hull work like it should.
