Thru Hull Exhaust on Force 220
 

Does anyone out there have thru hull exhuast on a mid 80's Baja Force
220?
I have a the 260hp 350 with the alpha and the Y pipe. I would love to
see a picture of any thru haul exhaust. I have all kinds of goodies
for this motor and the exhaust is holding me up on the upgrades.
Thanks

My Baja is still in storage for the winter so I can't show you any pics of
our set up.

@#%$#^! Weather this year!!

You can pick up a used set of 4"Corsa diverters on ebay pretty cheap.
I much prefer the electric ones vs the air actuated.
Tips are cheap too....get internal flappers AND add external ones too.
You will also need some 4" exhaust hose and 12 - 4 1/2" clamps, and of
course some relays (solenoids have a HUGE draw, don't wire thru switch!) ,
wiring and a switch.
It's any easy project to do.
The scariest part is boring the holes in the transom.
The dimensions are easy to find free online, or email me and I'll give you
the Alpha dimensions.
Measure 500 times, drill a 1/4" hole to make certain, and bore away.
Adds LITTLE if any HP on a stock 350, you might pick up 50 RPMS .....but
sounds great!
If you plan on doing any real engine mods it's a step in the right
direction.

Good luck!

Don't have a baja but I added thru hull. Figure out the entire route
exactly and then drill small starter holes where you expect the centers to
go thru the transom. You can always fill a little hole, the 4" one is a bit
tougher. I sealed the exposed transom with epoxy after cutting the holes.
One other note the steering cylinder on the later alphas has more clearance
above it that the earlier ones. Also make sure you want to. It will be
much much louder. Forget about conversations while running. I used corsa
silent choice and even when the thrus are closed a good deal of the sound
still gets thru. I have a 300+ 350 and opening the thru hulls adds a about
2 mph to the top end. I'm doing about 60. You have to keep in mind the
thru prop is really not very restrictive for a 350 displacement engine.
