So what you put in it? Reeds, performance heads, lighter flywheel, etc. We want gear head details  ;D

Outback outboards does my machine work

this what he did motor started as a 1995 2.5 200efi

he put 2 new sleeves

cut the exhaust like a 300 drag ( ill post some pics)

raised the intake ports

opened the rod slots

John Marls top pined my pistons

I lighted and Balanced my rods and had them shot pinged

I took 50thounds off my front half

I removed all the flashing's from the inside of my front half and intake then glass beaded the inside

my reed blocks are the 5 petal rubber coat blocks that come from a sport jet motor (very hard to find )

my reeds are from CCM Chris Carson Marine there the drag reeds

my computer is a Brucatos PCU (programmable control unit )

my heads are 33cc angle cut they push 148psi cranking compression done by Outback

if you look you can see i have a 1inch spacer between the intake and front half

The flywheel was done by Outback also it is about 4 pound (Turns up fast )

I have a 1pice Exhaust plate with a short bell tuner and the plate is dry stacked

I run the off shore midsection with the exhaust coming out above the water

the lower unit is a 200 case with a bobs nose cone low water pickup torque tamer welded to the skeg and the nose has the 2deg drop for the Allison haul

this motor can turn much more the 8000 RPMs but i have the limiter set at 8 grand

i run 2 props on this boat 1 is a 28 hoss and the other is a 30 Allison cut chopper

when you nail the gas it trows you back in the seat and pulls like a train until you lift your foot this the strongest boat i have ever set in and its 21ft long bass boat. I had a 20cc Bullet with a 260 merc and this Allison is stronger 8-) i hope i coverd every thing for you guys

How's it for trolling ;D

not bad

That's more like it, I am sure you could put that motor on a lead sled Ranger and be amazed.  The light flywheel makes a HUGE difference on the hole shot.   

What advantage does the offshore mid section give you, is it a exhaust back pressure issue?
