Decided to sell my Sidewinder engine.
1987 150 XR2 (2.0L)
Selling because I blew up the lower unit and don't plan on repairing. Have another engine I will be putting on it so this needs to go.
The powerhead:
85 hours on it since rebuild in 2010 (honed/rings/bearings/gaskets)
Oil injection removed.
Compression 120 on all six.
Always mixed 45:1 with premium+ only and fresh fuel or 91shell if sitting for a couple weeks.
Properly broken in for full 10 hours
Runs great and starts really easy.
Never taken past 6000rpm since rebuild
Have 2 cowlings - blacked out hood with louvers and original xr2 one
The mid:
Properly drilled mid that won't crack - same as the merc bass mid
Removed exhast liner (can)
"Sounds like a 260"
My neighbours hate it but that only makes me love it more
Powerhead - $1700
with drilled mid - $2200
Old video but its a youtube classic: http://www.youtube.com/watch?v=DleIcwsJpD0
